Abstract:
In these days, due to appreciation of a high yen rate, the Japanese industries, particularly export industries encounter severe conditions such as downsizing in plant and
equipment investment, thus, low cost and high efficiency are further required.
Since there is a few natural resources in Japan, it is necessary to develop products each of which is produced from a cheap material, can be useful for long period, has
small size and weight, and has high quality and additive value. This necessity is related to the proposition for conservation of natural resources.
The WPC Treatment is one of the working methods meeting with the necessity. The WPC Treatment is heat treatment for surface of a metal product characterized in that shot of
40 to 200µ having the hardness being equal to or higher than that of the product is injected against the surface of the metal product at the injection rate of 100 m/sec or
faster so that the temperature near the surface is increased to A3 transformation point or higher. (See Japanese Patent No. 1594395 owned by Fuji Kihan Co., Ltd. and Fuji
