Type K + Y-coat treatment
This is a composite treatment in which a hardening treatment (Type K) is applied to the metal material and Y-coat is applied on top of it.
The synergistic effect of “material hardening + Y-coat” provides an effect greater than that of conventional ion plating coatings.
Cross-section of film
Features
- Greater abrasion and galling resistance, softening resistance, fatigue resistance, etc.
- Dimensional changes are also the same as for Y-coat only.
Precautions
- Materials such as stainless steel, cemented carbide, etc., for which the hardened layer is difficult to diffuse, may not be sufficiently effective.
Abrasion and galling resistance
Y-coat only
Type K + Y -Coat
The hardening of the base metal surface layer makes it difficult for foreign matter and burrs to penetrate. Also, since the deformation of the base metal due to penetration is minimized, the coating film can easily follow and the chipping breakdown of the film is reduced.
