Abstract

PURPOSE:To subject external parts for timepieces on which Ti is ion-plated to a surface treatment to improve the adhesion strength, corrosion resistance, durability, etc. of the surface film thereof by depositing a Ti compd. or Ti alloy as the surface film by ion plating on said external parts. CONSTITUTION:Cu is plated on the surface of, for example, a watch case made of brass and after Ni is plated thereon, Cr is plated thereon. Ti is ion-plated to <=1mu on the surface of the resulted brass-chrome plated case and TiN is immediately ion-plated thereon as a surface film to <=1mu thickness. The watch case subjected to the surface treatment in the above-mentioned way has a golden color on the surface and has the high quality feel equivalent to the feel of a case subjected to gold plating. The surface of such watch case is extremely hard and the wear resistance is much higher than the wear resistance of not only the gold- plated watch case but also the watch case on which a chrome plating film is formed. The watch case has also the substantial corrosion resistance and has the substantial adhesion strength of TiN.

Currently, stainless steel, brass, zinc, aluminum, titanium, etc. are used as materials for the exterior parts of watches (watch cases, dials, crowns, buttons, watch bands, etc.). , titanium, etc. are materials with poor corrosion resistance, and because they oxidize, discolor, or corrode, exterior parts for watches made of these materials are used with gold or chrome plating applied to the surface. ing.

However, gold-plated watch exterior parts are expensive due to the high cost of plating materials;
Since the old gold plating film is soft and has poor abrasion resistance, it is easily scratched, and the plating film is worn away and the plating peels off, resulting in poor durability.

Although chrome-plated watch exterior parts do not have the luxury feel of gold-plated parts, they have the advantage of being obtained at a low price due to the low cost of plating materials, and the wear resistance of the plating film ( However, it cannot be said that the wear resistance is sufficient, and the corrosion resistance of the plating film is also not sufficient, so it may wear out after long-term use. It is inevitable that the plating will peel off due to scratches, abrasion or corrosion of the plating film, and therefore cannot be said to have sufficient durability.

On the other hand, among the exterior parts for watches, watch cases are generally manufactured by casting, which is then cut into shapes and finished by polishing the surface. For the sake of design, it is preferable for the corners and the corners around the case of a square case to have a shape with clear and sharp ridgelines, so stainless steel cases etc. have their corners cut with diamonds to have sharp ridgelines. It is processed and polished to finish. However, in cases where the surface is plated with gold or chrome, such as watch cases made of materials such as brass, lead, aluminum, or titanium, the wear resistance of the plating film is not sufficient (force), so the corners of If the edges are made sharp, the plating film in this area will be more easily damaged, and the plating film will become more abrasive, causing the plating to peel off quickly. It was believed that there was no choice but to extend the life of the plating as much as possible.

The present invention was made in view of the above-mentioned circumstances, and its purpose is to improve the abrasion resistance of the surface of exterior parts for watches far more than those using gold plating or chrome plating as the surface film. In addition to increasing the height, the corrosion resistance is also sufficiently high to make the component surface sufficiently strong against scratches and peeling.
Another object of the present invention is to provide a method for surface treatment of exterior parts for watches, which can greatly improve durability by sufficiently increasing the adhesion strength of the surface film.

That is, the method for surface treatment of exterior parts for a watch according to the present invention includes:
This is a method in which titanium is ion-blated on the surface of the exterior parts of watches, and then a titanium-based compound or titanium-based alloy is ion-blated on top of that as a surface film. It has extremely high hardness and excellent corrosion resistance, so according to the present invention, the abrasion resistance of the surface of watch exterior parts is much higher than that of gold-plated or chrome-plated surfaces. It is also possible to make the load resistance sufficiently high, making the component surface sufficiently strong against scratches and peeling, and greatly improving durability. However, since the titanium-based compounds and titanium-based alloys do not have very good adhesion to FI materials, for example, even if the surface is chromium-plated or made of soft material, the surface may not adhere properly. If a titanium-based compound or titanium-based alloy is ion-blated directly onto parts that have become hard due to oxidation, the adhesion will be unreliable, but with the present invention, the adhesion is extremely strong even to hard objects. It has high softness and is the same kind of titanium as titanium-based compounds and titanium-based alloys, and is ion-blated on the surface of the part, and then a titanium-based compound or titanium-based alloy is ion-blated on top of it. It is also possible to improve the adhesion of the alloy.

After plating Ni) to a thickness of 3 to 10μ, chromium (C
The surface of the yellow 111m chrome-plated case (chrome plated surface) is coated with titanium (Ti) to a thickness of 1μ or less, and then ion-bladed with titanium (Ti) to a thickness of 1μ or less, and then as a surface film. TiN was ion-plated to a thickness of 1 μm or less. Note that if the case is left in the air for a long time after the titanium ion blating, the surface of the titanium film will oxidize and become hard, so the titanium nitride ion blating should be carried out as soon as possible after the titanium ion blating. It is a good idea to do it.

The surface of the watch case treated in this way has a golden color, and therefore a watch case with the same high-class appearance as a gold-plated case can be obtained at a low cost.

The surface of this watch case is extremely hard, and its wear resistance is much higher than that of gold-plated or chrome-plated surfaces, and it also has excellent corrosion resistance. Moreover, the adhesion strength of titanium nitride was also sufficient. The surface of this watch case is extremely resistant to scratches and peeling, and there was almost no scratching or peeling, even on the sharp ridges of the corners.

In addition, in this example, if titanium carbide (Tic) was ion-blated as a surface film instead of the titanium nitride (the film thickness was less than iμ), the surface of the watch case would become white, and the wear resistance of the case surface would be improved. The corrosion resistance and adhesion strength of the surface film were almost the same as those obtained by ion-blating titanium nitride.

The copper plating used in the production of the above-mentioned brass chrome-plated case is to improve the adhesion of the nickel plating film to the brass case, but in the case of a brass case, nickel plating is applied directly to it. Since the adhesion of the nickel plating film is not so bad, the copper plating may be omitted. In addition, in the above example, the surface of the brass case is plated with nickel as a corrosion-resistant film to prevent corrosion of the case, and on top of that, chrome plating is applied to increase the hardness of the case surface, and then surface treatment is performed by ion blating. However, the same effect as above can be obtained even if the surface treatment is performed directly on the nickel plating by ion blating without performing the chromium plating treatment.

(Example 2) Copper (Cu) was added to the surface of a zinc (Zn) watch case whose corners were sharply processed by diamond cutting.
After plating to a thickness of 10 to 20μ, chromium (Cr
) is plated to a thickness of 1μ or less, titanium (Ti) is ion-bladed to a thickness of 1μ or less on the surface of the case, and titanium nitride (TiN) is coated on top of it as a surface film of 1μ or less. Ion blasting was done at J Fusa.

In this case as well, the color of the case surface is gold, and the wear resistance and corrosion resistance of the case surface and the adhesion strength of the surface film are as described above (
The result was the same as in Example 1). When titanium carbide (TiC) was ion-blated in place of the titanium nitride mentioned above, the color of the case surface became white, and the wear resistance and corrosion resistance of the case surface and the adhesion strength of the surface film were also sufficient. Ta. In addition, even in the case of zinc cases, it is possible to perform surface treatment by ion blating directly on the nickel plating without performing chromium plating.
In that case as well, effects similar to those described above can be obtained.

(Example 3) Titanium (T1) was directly ion-bladed to a thickness of 1μ or less on the surface of a titanium (Ti)i watch case whose corners had been sharpened by diamond cutting.
When we ion-blated hardened titanium (TiN) as a surface film on top of it to a thickness of 1μ or less, the color of the case surface turned golden.We ion-blated titanium carbide (TIC) in place of the titanium nitride. The color of the case surface turned white. Furthermore, the titanium case and the surface films of titanium nitride and titanium carbide are the same type of material, and while solid titanium itself is soft, the surface of the titanium case may become hard due to oxidation. If titanium nitride or titanium carbide is ion-bladed directly on the surface, the adhesion strength may be weakened, so ion-blazing of titanium is essential to improve the strength.

The watch case surface-treated in this way also had very high abrasion resistance and corrosion resistance on the surface, adhesion strength of the surface film, etc., and was able to obtain the same effects as the above (Example 1).

In addition, although the above three examples have been listed here, there are other ways to ion-brate titanium directly to aluminum watch cases and stainless steel watch cases, and in the case of aluminum cases, the aluminum itself is soft, but the surface (In the case of stainless steel cases, the case material itself is hard, so ion blasting of titanium is essential.) The same effect as in the above example can be obtained by ion-blating the watch case.For watch cases made of soft materials such as titanium cases and aluminum cases, the surface of the watch case can be hardened by applying chrome plating etc. After that, surface treatment by ion blating may be performed.

Even if these are used, the same effects as in the above embodiment can be obtained, and the above various titanium compounds (TiN, Tic,
TIO) and titanium alloys (T1Co, T1Cr
) Depending on which one you use, the color of the case surface can be gold, white, wine color or purple. There are two methods of ion-blating Tico and T1Cr: one is to create titanium-based alloys and evaporate them, and the other is to evaporate titanium and cobalt or chromium all at once to coat the case surface with the alloy. There are several ways to generate it.
