工性が悪いという大きな欠点を有していた。Conventionally, 5US316L material has been used for exterior parts due to its corrosion resistance, workability, and cost. 5U
S51 (5L material is mainly used as body and band material, but it cannot necessarily be said that it has sufficient corrosion resistance against corrosion in the gaps between the body and back cover, the body and edges, and between the pieces of the band. In addition, when plating is applied, the surface is activated, so there is no passive film, which makes it more susceptible to corrosion than the base metal, and corrosion occurs due to the potential difference through the plating pinholes, and corrosion occurs between band pieces, etc. The gap had the disadvantage of being exposed to the worst corrosion conditions because the plating did not adhere to it.To compensate for this disadvantage, highly corrosion-resistant materials such as Hastelloy and Inconel were used. It is a well-known fact that these materials are 5 to 10 times more expensive than ordinary stainless steel, and are
The drilling of minute holes in the mechanical band piece shown in the figure, the side gun holes shown in Fig. 2, and the machining of spring true holes 1, etc., have short tool life, slow processing speed, and poor finish. It had a major drawback of extremely poor machinability.
本発明者は、かかる欠点を除去すべく、種々検討した結

ｉ図である。In order to eliminate these drawbacks, the inventor of the present invention has conducted various studies and found that it is easy to process, the cost is the same as or lower than that of conventional stainless steel materials, and that it is superior to Hastelloy and Inconel in terms of corrosion resistance. It was possible to obtain an exterior part with equivalent corrosion resistance. The following will be explained based on examples.

The base material 5 is arbitrarily selected depending on cost, strength, and processing method, and after being processed into a rough shape, it is immersed in a molten metal of a highly corrosion-resistant material such as Hastelloy or Inconel, and is spread onto the surface layer, and then molded with a mold. , final shape. With this method, the base material 85 and the highly corrosion-resistant material 6 on the surface layer are firmly bonded together through diffusion bonding, so they will not peel off even during the subsequent molding process, and the base material 5 A state is obtained in which the surface is covered with the highly corrosion-resistant material 7. In terms of processing costs, it is extremely easy to process up to a rough shape, and only needs to be processed once after being coated with the highly corrosion-resistant material 6, which is difficult to process, so there is less wear and tear on the mold. Compared to the case where this method is used, processing can be performed with a few minutes of processing man-hours. As described above, according to the present invention, an inexpensive material with good workability is used as the base material,
Easy to obtain exterior parts with good corrosion resistance
