Tribobond™ 30 CrN

High temperature resistant coating with excellent toughness

Tribobond™ 30 CrN has a good combination of properties; high hardness, excellent toughness, high wear and impact fatigue resistance. Tribobond™ 30 resists temperatures of up to 700 ºC making it a good candidate for high temperature applications. It features a lower residual stress than many other coatings allowing the deposition of thicker layers.

Tribobond™ 30 CrN is often used as an environmentally friendly replacement for electroplated hard chromium. It can be deposited directly onto the machined components and does not require grinding back to size.

Tribobond™ 30 CrN protects against sliding and impact fatigue, oxidation, fretting and adhesive wear. It has a low friction coefficient against steel and good abrasive wear resistance.
