Welding has no problem in terms of bonding strength and corrosion resistance, but partially heats to high temperature and locally melts, exceeding the transformation point of Ti, causing a coarsening of the crystal structure. In order to increase the size of the decorative part, the decorative part cannot be used in appearance. Further, in the case of projection welding, which is a type of welding, if the structure of the members to be joined is complicated, it is difficult to uniformly concentrate the current on the projection portion, and welding may be difficult.

Table 1 shows the relationship between the melting point and the wettability to Ti of each composition (% by weight) of a PdNiP (Ti) -based ternary or quaternary alloy as one composition of the present invention. When the proportion of P is less than 6% by weight (sample A) or more than 17% by weight (sample J), the melting point tends to increase, and the transformation point of Ti, which is the object of the present invention (882 ° C.) ) The following joining becomes impossible. Further, in Sample B having a small Ni content of 3% by weight, the wettability to Ti tends to be insufficient, and in Sample H having a content of 34% by weight or more, an increase in the melting point has also been confirmed, which is undesirable. Here, data on the corrosion resistance and the joining strength of the brazing material are not described, but the corrosion resistance and the strength were all sufficient values.

ことから、なお望ましいロウ材となることがわかった。Therefore, in the case of a PdNiP-based ternary alloy, which is one composition of the brazing filler metal of the present invention, when P is in the range of 6% by weight to 17% by weight, bonding, corrosion resistance and bonding strength below the transformation point of Ti are not improved. It was found that it could be a brazing filler metal that could satisfy all. Further, in the above composition, if Ni is contained at a ratio of 4% by weight to 32% by weight, the brittleness of the brazing material is eliminated, and the wettability to Ti is improved. I understand.
【００２０】以下に、上記組成がロウ材として望ましい
理由を理論的に裏付ける。図１にＰｄ−Ｐ２元系の状態

する。図１に示すようにＰｄとＰはＰｄが９４重量％、
Ｐが６重量％の時に共晶組成となり、融点が大幅に低下
する。この共晶点を第１共晶点とする。Hereinafter, the reason why the above composition is desirable as a brazing filler metal is theoretically supported. FIG. 1 shows a phase diagram of a Pd-P binary system, and the intended purpose of the brazing material composition of the present invention will be described. As shown in FIG. 1, Pd and P are 94% by weight of Pd,
When P is 6% by weight, a eutectic composition is obtained, and the melting point is significantly reduced. This eutectic point is referred to as a first eutectic point.
【００２１】また同様に、Ｐｄが８８重量％、Ｐが１２

The eutectic is formed even when the content is in the range of weight%, and the melting point is significantly reduced. This eutectic point is referred to as a second eutectic point.

ても適当な量の範囲が存在することが予想できる。One brazing material of the present invention utilizes the above-mentioned first eutectic point, and adds Ni, which dissolves completely with Pd, to this composition. Although the addition of Ni has the effect of improving the wettability to the metal member material to be joined or removing the brittleness of the brazing material,
At this time, the added Ni becomes a form to be substituted for Pd, and if the amount is too large, it is deviated from the eutectic composition, so that the melting point is increased or it is difficult to form a uniform solid solution. That is, in the case of PdNiP,
Can be said to be a composition utilizing the first eutectic point in the composition range containing 6 to 10% by weight, and it can be expected that Ni also has an appropriate range.

量％が適当であった。Further, another brazing material of the present invention utilizes the above-mentioned second eutectic point, and adds Ni, which dissolves completely with Pd, to P
Similarly, in the composition range in which P is contained by 10 to 17% by weight, the composition using the second eutectic point can be said to be a composition using Ni. In addition, Ni may have a suitable range. Can be expected. Therefore, when the above compositions are combined, P is 6 to 17% by weight in the PdNiP system.
Within the included composition range, it can be said that the composition becomes a homogeneous alloy with a low melting point using the first eutectic point and the second eutectic point, and can be brazed below the transformation point of Ti.
Further, in the composition, the ratio of Ni is preferably 4% by weight.
If the content is in the range of 30 to 32% by weight, a uniform alloy with a low melting point, no brittleness and a good wettability can be obtained.
Further, a composition obtained by adding a small amount of Ti to the ternary composition (sample K in Table 1) is a good brazing material composition because the wettability to Ti is further improved. An appropriate amount of Ti added was 1 to 5% by weight.

で接合したサンプルを作製し表２に示す。(Second Embodiment) Similar to the first embodiment, the PtNiP-based alloy also has a desirable composition range as the brazing material of the present invention. The phase diagram of the Pt-P binary system is shown in FIG. Another brazing material of the present invention is the P brazing material shown in FIG.
The eutectic point of tP is used, and an appropriate amount of Ni, which is in solid solution with Pt, is added to 96% by weight of Pt, which is the eutectic composition of Pt and P. Although detailed experimental data are not shown here, in the PtNiP ternary composition, in the composition range where P is contained in the range of 3 to 7% by weight, the alloy becomes a low melting point and uniform alloy utilizing a eutectic point, and is suitable as a brazing material.
It was found that the composition could be brazed below the transformation point of Ti. Also, as with PdNiP, there is an optimum composition for the Ni content, and the Ni content is 2% by weight to 31%.
When the composition is wt.%, A homogeneous alloy with a low melting point is obtained.
It was found that the wettability and fragility to i can be improved. (Third Embodiment) As a third embodiment, a metal member joined by using the brazing material of the present invention will be described with reference to FIGS. As shown in FIG. 3, one metal member 7a of the present invention includes a first metal member 1a, a stainless steel plate, and a second metal member 1a.
This is a metal member formed by interposing the brazing material 3 (Pd 70 Ni 15 P 15 ) between stainless steel plates as the metal member 1b. As shown in FIG. 4, the other metal member 7b of the present invention has a brazing material 3 (Pt 80 N) between the Ti as the first metal member 1c and the Ti as the second metal member 1d.
i 15 P 5 ) and a first diffusion layer 2 a and a second diffusion layer 2
Are bonded together with the diffusion layer 2b interposed therebetween. The two diffusion layers are formed by forming a thin film made of Pt in advance by ion plating on the joining surface of the first and second metal members Ti, so that the metal members Ti and the metal Pt formed on the joining surface of the member is formed by causing mutual diffusion. That is, the diffusion layer was a diffusion layer of Pt and Ti. The metal thin film is used not only for increasing the bonding strength by forming a diffusion layer but also for improving the wettability of the brazing material. Particularly when the shape of the surfaces to be joined is complicated, if the brazing is performed only with the brazing material without forming the metal thin film, the joining strength may be insufficient. In such a case, it is desirable to form the thin film. Although Pt is shown as the material of the metal thin film, other materials may be selected from Cu, Ni, Au, Pd, Ag, and metal thin films of these alloys. (Fourth Embodiment) Next, a manufacturing method for joining metal members using the brazing material of the present invention will be described. First, a method for producing the brazing material of the present invention will be described. Pd in Ar atmosphere
Each element was weighed so as to have a composition of 82 Ni 10 P 8 , and a metal was melted by an induction melting method in an Ar atmosphere to prepare an alloy. Thereafter, it was processed into a ribbon shape having a thickness of 60 μm and used as a brazing material. Also, Ti was used as the first and second metal members, and an AuCu alloy metal thin film of 2 μm was formed on both surfaces of each bonding surface by ion plating. Subsequently, Pd 82 which is the brazing material 3 of the present invention is provided between the joining surfaces of the first metal member and the second metal member on which the metal thin films are formed.
Ni 10 P 8 was sandwiched, and they were fixed with a predetermined jig. Then, after inserting them into a vacuum furnace and evacuating them, at 800 ° C. below the transformation point of these metal members,
Heated for hours. At this time, AuCu, which is a metal thin film, improves the wettability of the brazing material and causes mutual diffusion with Ti, which is the first and second metal members, by heating at the time of brazing, so that T
A diffusion layer, which is an intermetallic compound of i and Cu, and Ti and Au, was formed, and a metal member having sufficient bonding strength was formed. (Fifth Embodiment) Next, an embodiment in which the brazing material of the present invention is applied to an actual industrial product will be described. FIG.
FIG. 3 is a perspective view of a Ti ring made by using the brazing material of the present invention, and although it is apparent from the appearance that the ring is an integral part, actually, a joint portion using the brazing material of the present invention in a part thereof. have. This ring was manufactured by the following steps. The Ti plate material was rounded by hot forging, and processed into a ring shape having a notch at one location. After that, the outer surface of the ring was finished to a mirror surface by buffing, and the cutout had a composition of 89% by weight of Pt, 6% by weight of Ni, and 4% by weight of Pt.
The brazing filler metal having the composition described above was inserted and fixed. Then, after setting in a vacuum furnace and evacuating to a degree of vacuum of 6 × 10 −6 Torr, 70
It was heated at 0 ° C. for 10 minutes, and then cooled in an Ar atmosphere. As a result, the brazing material is completely filled in the notch portion and joined, and also in this embodiment, since the joining is performed at the transformation point of Ti or less, the crystal structure is not coarsened, and the surrounding mirror surface is not formed. It was held, and only the vicinity of the joint was integrated externally by a simple polishing process. In addition, the strength of the joint was not problematic in use. In this embodiment, the first metal member and the second metal member are Ti, which is the material of the ring, and are the same member. Thus, it can be seen that the present invention can be applied to a case where the first metal member and the second metal member are the same member. (Sixth Embodiment) Next, an example in which the present invention is applied to the joining of the leading can part of a watch case as a watch exterior part will be described with reference to FIG. Conventionally, a watch case is generally manufactured as an integral part, including a leading can part for connecting a band. However, in recent years, there has been a demand for finishing the case main body and the front can part in different surface states due to a demand for an increase in design flexibility. For example, there is a demand that the case body has a mirror surface finish, and the leading end portion has a hairline surface finish. However, conventionally, the case main body and the front can part are manufactured as an integral part, and have continuous surfaces, so that it was difficult to properly bring out the interface between the mirror surface and the hairline surface. Furthermore, in the case of the integrated type, the design by the forging method, which is cost-effective as a manufacturing method, has a great restriction on the shape of the first can part. Furthermore, the hole for inserting the spring bar for attaching the band to the front can part was formed by a drill later, but if the hole is visible from the outside, it is not preferable in appearance, so no hole is made outside the front can part. It was open from the inside. For this reason, in many cases, the opposing leading end portion interferes during processing, and therefore, the conventional spring rod hole is processed not at right angles to the processing surface but at an angle. Therefore, it was necessary to make a hole slightly larger than the spring bar, and there was some backlash. Drilling was also difficult. FIG. 6 is a perspective view of a timepiece component using the joining method of the present invention for joining the leading can portion. The watch case main body 11 and four front cans (12a, 12b, 1
2c and 12d) are joined using the joining method of the present invention. The case body is Ti
It is made of an alloy, and each is formed by forging and ground and polished. The outer surface of the outer part except for the joint surface was processed with a hairline surface. The case body was mirror-finished, including the joint surface. In addition, a hole of the spring rod hole 14 was formed in advance on the leading end part. Thereafter, a 3 μm-thick Cu plating is performed on the joining surface of the leading can part, and then a brazing material having a composition of 82% by weight of Pd, 10% by weight of Ni, and 8% by weight of P is sandwiched between the interfaces and pressed and fixed with a jig. Heating was performed at 700 ° C. for 20 minutes in a temperature of 6 × 10 −6 Torr, and then quenched in an Ar atmosphere. As a result, the brazing material of the present invention is used for the watch case 11 and each of the leading can parts (12a, 12b, 1).
It completely penetrated into the joint between 2c and 12d) and was also integrated in appearance. Also in this example, since the heating was performed at a temperature lower than the transformation point of Ti, the crystal structure was not coarsened, the surface state before joining was maintained, and the interface between different surfaces in the case and the first can was formed clearly. . Further, the joint had sufficient tensile strength. In the present embodiment, the first metal member was Ti as a watch case, and the second metal member was a Ti alloy as a first part. It can be seen that there is no problem even if the first metal member and the second metal member are not the same kind of metal member but different kinds of joints as in the present invention, and there may be a plurality of joints. (Seventh Embodiment) Next, Table 2 shows the results of measurement of the corrosion resistance test and the joint strength test of the metal member of the present invention. A sample in which the first metal member and the second metal member are both made of a Ti plate material and joined using a brazing material having a composition of 8 % by weight of Pd 82 Ni 10 P, which is the brazing material of the present invention; After 10 μm thick Cu plating was performed on both sides of the plate material, 8 % by weight of Pd 82 Ni 10 P as the brazing material of the present invention was used.
The results obtained by producing a sample joined by using a brazing material having the following composition and measuring the tensile strength by a CASS test and a tensile test specified in ISO 3370 as a corrosion resistance test are shown. For comparison, conventionally known Ag-based brazing materials Ag 58 Cu 32 Pd 10 and Ti-based brazing materials Ti 75 Cu 10 Ni 25
Table 2 shows a sample bonded by the above method.

The metal member joined by using the dNiP-based brazing material showed good corrosion resistance, and the joining strength also showed a sufficient value as compared with the conventional brazing material. In particular, the sample in which a diffusion layer was formed by forming a Cu thin film showed high bonding strength. When the cross section of the bonding portion was analyzed, mutual diffusion occurred at the interface between the base material Ti and the Cu plating film formed on the surface. And the formation of an intermetallic compound of Ti and Cu. It is considered that sufficient bonding strength was obtained due to the presence of the diffusion layers confirmed on both sides of the brazing material. Further, in Examples 1 and 2 of the present invention, since bonding at the Ti transformation point or less is possible, Ti
The crystal structure does not become coarse, the surface state before joining is maintained, and there is an advantage over the conventional TiCuNi-based brazing material. It can also be said that it is very excellent in corrosion resistance in comparison with Ag-based brazing filler metals. As described above, in the joining using the brazing material of the present invention, good corrosion resistance, sufficient joining strength, and joining satisfying all joining at or below the transformation point of Ti can be realized. (Other Embodiments) In the above embodiment, an example was described in which PdNiP or PtNiP was added with Ni which completely dissolved in Pd and Pt. However, the present invention is not limited to this. If there is, there is a possibility that it can be replaced. Further, as described above, the brazing material of the present invention can be joined to the brazing portion between the Ti members with the brazing material interposed therebetween. However, if the interface has a complicated shape or wettability is required, the joining surface is It is effective to braze with a metal thin film. Cu, Ni, Au, Pt, P
d, Ag, or an alloy thereof may be used. Further, this metal thin film may be provided on one side of the surface to be brazed, or may be provided on both surfaces. The film formation method may be plating, ion plating, evaporation, sputtering, CVD, or the like. Further, as mentioned in the first embodiment, the brazing material PdNiP or PtNiP of the present invention is added with 1 to 5% by weight of Ti.
May be added to form an activated wax. This T
Although the introduction of i slightly raises the melting point, it has the effect of improving the wettability and the workability of the brazing material. In the present invention, the metal member that is satisfactorily bonded is Ti, but a typical Ti alloy, for example, Ti-6Al-4V has a transformation point of 99.
Even when applied to a Ti alloy, as in the case of 5 ° C., there is no particular limitation on its composition. The present invention is also applicable to a case where brazing is performed using another metal member such as stainless steel. In addition, the brazing material of the present invention is desirably made of a plate, a foil, or a linear shape, but since a brittle composition is also included depending on the composition, in such a case, after being made into a powder, it is used after being compacted and molded. You may. Heating temperature at the time of brazing is 620
To 850 ° C, preferably 650 to 750 ° C, the brazing time is 5 minutes to 1 hour, and the atmosphere in the furnace during brazing is 10
It is preferable to set the degree of vacuum to -4 Torr or less.
