3) proportion and the metallographic of ferrite system, above-mentioned proportion is such as 8,8.5,9,9.5,10,11,12,15,16 or 17g/cm
3, but be not limited to this.
As mentioned above, after metal-powder ejection formation (MIM), described balancing weight alloy 70 has the reduction in bulk of slight extent compared to described germule 40, its tolerance of dimension is between ± 0.5%, and owing to using the diameter of particle (0.1 to 45 μm) thinner than prior powder metallurgy, therefore the high-compactness of more than 95% after powder sintering of the present invention, can be obtained, its performance is all obviously better than the tolerance of dimension (± 0.7%) of prior powder metallurgy (diameter of particle about 50 ~ 100 μm) and the performance of density (<92%).Compared to conventional metals processing (as casting, forging or prior powder metallurgy) complicated program and cost, metal-powder ejection formation (MIM) is few because having work program, without cutting or few cutting, can the advantage such as batch volume production, therefore not only significantly can enhance productivity and effectively reduce volume production cost, and be also suitable for the high-accuracy size of a large amount of production, complex-shaped mini golf club head component (as balancing weight), and the material that can overcome prior powder metallurgy handicraft is smoothly uneven, mechanical property is low, the not easily shortcoming of forming thin-walled or complex construction.
Moreover, please refer to shown in Fig. 2 F, present pre-ferred embodiments is after utilizing the obtained described balancing weight alloy 70 of the step (S01) to (S05) of above-mentioned balancing weight alloy manufacturing methods, another alternative implements a step: by described balancing weight alloy 70 solder bond on a rod head noumenon 80, to be jointly assembled into a golf club.In this step, described golf club refers to the iron club of two-piece type (two-piece) especially, described balancing weight alloy 70 preferably solder bond in the bottom of described rod head noumenon 80, to reduce the overall position of centre of gravity of iron club.
Please refer to shown in Fig. 3 and Fig. 4, in this step, described golf club can also be selected from the rod head noumenon 80 ' of Fairway Woods or the rod head noumenon 80 of mixed-blood bar "; now; described balancing weight alloy 70 ', 70 " be preferably combined in described rod head noumenon 80 ', 80 with welding process " and rear bottom or other be suitable for adjusting the position of center of gravity, to reduce the overall position of centre of gravity of Fairway Woods or mixed-blood bar.
Please refer to shown in following table 1, it discloses several different embodiments (MIMD9 ~ D17) of the present invention and utilizes the metal-powder ejection formation (MIM) of above-mentioned steps (S01) to (S05) to be made into the final metal proportion of composing after balancing weight alloy 70, and the proportion of described balancing weight alloy 70 is 9-17g/cm
3.Moreover, the rod head noumenon 80 of above-mentioned balancing weight alloy 70 with an iron system material is welded, then tension test is carried out to it, the tensile strength of the weld between described balancing weight alloy 70 and rod head noumenon 80 can be obtained between 15 to 90ksi.Above-mentioned solder bond mode can be laser (laser) welding, ion welding or argon arc welding; The welding rod that welding uses can be 329,312,630,308 welding rods; And the iron system material of described rod head noumenon 80 can be stainless steel based material (as 17-4,431 etc.) or soft iron class material (as 8620, S25C etc.), but be not limited to this.
Table 1,
As mentioned above, compared to conventional metals processing (as casting, forging or prior powder metallurgy) the shortcomings such as weldability is not enough, first the present invention of Fig. 1 and Fig. 2 A to 2F prepares a metal mixed powder 10, comprise the tungsten powder 11 of 10wt% to 95wt%, and all the other weight percents are chromium-iron powder 12 and the nickel powder 13 of weight ratio 1:1 ~ 5, then above-mentioned metal mixed powder 10 and a cakingagent 14 is made to be mixed into stock again, to go forward side by side row metal powder ejection formation (MIM) manufacture method, hyperbaric balancing weight alloy 70 can be obtained by this, and by using described chromium-iron powder 12 to avoid forming metal oxide on the surface of balancing weight alloy 70, therefore the manufacturing cost of balancing weight can not only be reduced, and also can improve the weldability of balancing weight, and the soldering reliability increased between balancing weight and rod head noumenon.
The present invention is described by above-mentioned related embodiment, but above-described embodiment is only enforcement example of the present invention.Must it is noted that published embodiment limit the scope of the invention.On the contrary, be contained in the spirit of claims and the amendment of scope and impartial setting to be included in scope of the present invention.
