CrN coating

CrN coating
CrN coating

This is the standard for chrome coating and has excellent adhesion resistance, corrosion resistance, and slidability. The component elements are stable and may be used as a base for other coatings to prevent corrosion.

CrN coatingのレーダーチャート

Hardness is inferior from TiN, but it has excellent heat resistance and slidability.

Corrosion resistance

The internal stress is lower than titanium, and stable coating with fewer pinholes. It is used in die-cast pins, resin molds, and rubber molds so on.
