Tribobond™ 31 Cr2N

Low stress wear resistant coating with smooth surface

Sub-stoichiometric Tribobond 31 Cr2N  features  lower  residual  stress  than  many  other  coatings from the Tribobond portfolio,  including CrN. Since the coating is produced by sputtering it generally features lower roughness than cathodic arc coatings. Crystalline structure of this coating allows for excellent polishing properties. Tribobond 31 Cr2N  also exhibits lower surface energy, making this coating more hydrophobic.

In general, Tribobond 31 Cr2N protects against abrasive and adhesive wear, impact fatigue, oxidation and fretting.
