It was made into a single layer or multiple layers to achieve corrosion resistance and high quality.
又、AQメッキにおいては、耐食性が劣るため、メッキ
処理後のクリアーラッカーの塗布が必要である。Furthermore, since AQ plating has poor corrosion resistance, it is necessary to apply a clear lacquer after the plating process.

In addition, since Au and AQ are used, the raw material costs are very high, and even if local plating is performed to reduce raw material costs, the current technology for both process and equipment requires an additional 1i.
It has the disadvantage of being complicated and expensive. Generally speaking, Ag plating has many drawbacks such as very poor corrosion resistance and the need to apply clear lacquer after plating, which is not economical.

せたものである。(Means to solve the problem) In order to add novelty to the design through multi-coloring, ensure higher quality than before, and reduce manufacturing costs, dissimilar metals are applied to the surface of the workpiece (base material). After partially removing dissimilar metals by coating and etching, nitriding (heat treatment) can be used to color the base material and improve adhesion by diffusion between the dissimilar metals. The present invention was completed by discovering that rolling is possible and that the thickness of the coated white metal can be controlled with high precision.
