Complex processing technology
Caused by colliding special fine particles such as HSS & ceramic on the surface, the hardness of the outermost surface will improve approx. 1.5 times compared to the original hardness. The dimensions of the base material will not change due to the small size of the particles.
The outermost layer's hardness to a depth of about 10µm increases by up to approx. 1.5 times that of the original layer. Caused by hardening the deposited surface of the coating, it is possible to improve adhesion, and only the surface is cured, so the toughness characteristics of the base material are maintained. In WPC processing, shot blasting forms a recess on the surface and the gloss is lost. PVD treatment is performed in our company after returning to the original glossy surface by lapping.
Stripping (coating film removal) of CVD processing and PVD process are provided by SEAVAC.
In particular, PVD processing is performed at temperatures below 500℃,
reducing thermal effects to the base metal, and also reducing the film cost by film removal reprocessing before the base material is severely damaged.
