Sliding Resistance Reduced! Improved Abrasion Quality!

Methods of WPC treatment is patented and jointly held by Fuji Manufacturing Co., Ltd. and Fuji Kihan Co., Ltd. (PAT.No.1594395)

Three primary effects of WPC Treatment

Surface Finish Heat Treatment

(Patent of Fuji Manufacturing Co., Ltd and FUJI KIHAN Co.,LTD)
Surface temperature of powder metallurgy alloy increases by fine particles peening, and metal binder in the powder metallurgy alloy will get soft, and each grain will combine solidly. Structure around the surface will be changed to be smooth and high hardness and adhesion of grains will be enhanced. Therefore, it is possible to increase wear resistance and durability of powder metallurgy alloy. Using this technique for cutting tool made of powder metallurgy alloy, we can obtain the cutting tool having the good wear resistance, durability, and increasing mechanical characteristic such as resistance to chipping.
Wear Prevention of Sliding Parts of the Metal Products

(Patent of FUJI KIHAN Co.,LTD)
On sliding parts of metal products, a lubricant is usually used. Under certain conditions, a lubricant dries up and friction occurs. By spraying abrasive, the surface structure becomes surface pressure resistant, creating small indents to make it difficult for lubricant to dry up, and making a near no-contact state, reducing the oil temperature and preventing the friction. When WPC treatment is applied on engine parts and other sliding parts, slide resistance is lower, increasing the power and providing higher fuel efficiency, and shortening the initial engine running-in period. It also prevents burns and scratches.
Diffusion at Normal Temperature Penetration Coating

(Patent of FUJI KIHAN Co.,LTD)
There is a limitation in physical property of a metal material. By spraying metal particles, its component element is diffused over the material surface and the diffused coating, and the surface gets alloyed, to strengthen the material. The treatment is used for pre-treatment of the plating and coating to increase the adhesiveness. By spraying metal particles of low melting point and low hardness, room temperature dry plating is possible.
