製造法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a metal material that becomes an eyeglass frame, and in particular, a method for manufacturing a metal material that uses titanium or a titanium alloy as a base material, and applies nickel plating with good adhesion to the surface of the base material. The present invention relates to a method for producing a material for eyeglass frames by applying nickel plating to the surface of a titanium or titanium alloy base material and then applying gold alloy plating to the surface.

いう欠点があった。Titanium and titanium alloys themselves are lightweight metals with excellent corrosion resistance, and are being used in various fields. However, because they are chemically very stable metals, they are difficult to shape when shaping products for eyeglass frames. The disadvantage was that it was difficult to braze.

である。However, as an attempt to eliminate this drawback, conventional titanium or titanium alloys are used as a base material, and nickel or fc nickel alloys or gold alloys, which have relatively good corrosion resistance, are coated on the surface using a metallurgical method. Some eyeglass frames made of gold-plated or gold-plated materials are on the market, but the manufacturing cost of coating titanium with nickel or gold alloy using a metallurgical method is very high, and the manufacturing cost is very high. A new drawback is that during the processing stage to shape the product into a frame, the nickel or gold alloy applied to the base titanium base metal partially peels off and disappears. There is nothing to expect from frame manufacturing, and it is far removed from practical use.

However, even with this method, there are 41 problems such as the occurrence of pinholes peculiar to plating and the adhesion between the matrix and the layer to be plated, which is inferior to that of tension materials. there were.

金属を完全に密着させる。■Furthermore, in order to subject the above material to the diffusion cylinder fIi treatment as the sixth treatment, heat annealing and thermal diffusion treatment are performed at a temperature of 600C for 20 minutes in a hydrogen atmosphere filled with hydrogen gas in an electric furnace. . This is to prevent deterioration due to metal oxidation, and this heat treatment, or thermal diffusion treatment, damages the base material titanium, the intermediate metal nickel plating layer, and the surface metal gold alloy plating layer. Mutual movement of material molecules occurs on each contact surface, and as shown in FIG. 2, a heat diffusion layer is formed on each contact surface, using this as a medium to completely adhere each metal.

材としては使用できなかった。As a result of repeated experiments, it has been found that when plating nickel, which is the surface metal or intermediate gold scrap, on a base material of titanium or titanium alloy, it is difficult to plate the base material of copper and copper alloy, iron and iron alloy, which are conventionally known. When using the same method as nickel plating, it is not possible to obtain a nickel plating layer with good adhesion on the base material of titanium or titanium alloy, and it is difficult to obtain a nickel plating layer that adheres well to the base material. The nickel plating layer peeled off from the base material and could not be used as a material for eyeglass frames.

If it is less than μ, the corrosion resistance of the gold alloy plating layer, which is the surface metal formed thereon, deteriorates, and very favorable results were not obtained in terms of corrosion resistance. When gold alloy plating is applied directly to the titanium base material without forming a nickel plating layer as an intermediate metal, the adhesion of the gold alloy plating layer to the base material becomes poor.

However, considering the deterioration of the base material, temperatures exceeding 800'C are unfavorable, while temperatures below 150'C result in poor il annealing and thermal diffusion effects. 150-800
The test shall be carried out within a range of up to ℃. In addition, the same effect was observed in diffusion annealing under vacuum or inert gas, and in this respect, the same effect was obtained when the base material was titanium and the surface metal of titanium alloy 1 and the intermediate metal were nickel and a nickel alloy.
