属合金の製造方法。[Claims] 1) Nickel is produced by electroless or electrolytic plating of nickel on any of noble metal powders such as gold, gold alloy, platinum, palladium, rhodium, silver, platinum alloy, palladium alloy, rhodium alloy, silver alloy, etc. A nickel plating process to form plating powder, and a predetermined amount of base metal powder such as pure titanium, titanium alloy, aluminum, aluminum alloy, nickel alloy, etc. is mixed with the nickel plating powder formed by this nickel plating process. It is characterized by including a press forming process of press forming into a shape, a sintering process of sintering the product that has undergone this press forming process, and a post-processing process of post-processing the product that has undergone this sintering process. A method for manufacturing a composite precious metal alloy. 2) Precious metal powders such as gold, gold alloys, platinum, palladium, rhodium, silver, platinum alloys, palladium alloys, rhodium alloys, silver alloys, and base metal powders such as pure titanium, titanium alloys, aluminum, aluminum alloys, nickel alloys, etc. 2. The method for producing a composite noble metal alloy according to claim 1, wherein the composite noble metal alloy is formed into particles having a size of several microns to several millimeters. 3) A patent claim characterized in that the plating film thickness of the nickel plating powder is from 100 angstroms to several tens of microns, which can prevent metal alloy diffusion of noble metal and base metal even after sintering temperature and form a distinct heterogeneous composite material. A method for producing a composite noble metal alloy according to item 1 or 2. 4) The method for producing a composite precious metal alloy according to any one of claims 1 to 3, wherein the press forming step is performed by cold pressing or hot pressing. 5) In the sintering process, if the nickel plating powder is gold and the base metal is pure titanium or titanium alloy, the sintering temperature is 105
Claim 1 characterized in that the process is carried out at 0°C or lower.
A method for producing a composite noble metal alloy according to any one of items 1 to 4. 6) If the nickel plating powder is gold and the base metal is an aluminum alloy or nickel alloy, the sintering process is carried out at a sintering temperature of 1000°C or less. A method for producing a composite noble metal alloy according to any one of the above. 7) The post-processing process includes a gold plating process in which the surface of the product that has undergone the sintering process is plated with gold, and a surface that is subjected to dry honing, polishing, or etching to expose the nickel plating powder material to the surface. According to any one of claims 1 to 6, the method comprises an exposure treatment step and a coloring step in which the base metal portion is colored by anodic oxidation, thermal oxidation, or chemical conversion treatment after the exposure treatment step. A method for producing the described composite precious metal alloy.
