Abstract

CrMoSiCN coatings were applied to Ti-6Al-4V titanium alloy substrates, and their electrochemical and tribocorrosion performances in seawater were studied systematically. When the coating polarization was conducted without sliding contact, the passive oxide film with MoO3 and Cr2O3 was formed on the surface of CrMoSiCN coatings to prevent the penetration of seawater. During tribocorrosion testing, the friction coefficient decreased but the material loss of coatings increased with increasing Mo content. This indicated that the tribocorrosion behaviors of CrMoSiCN coatings were closely related to their mechanical properties and electrochemical performance. Among all CrMoSiCN coatings, the CrMoSiCN-2 coating possessed the best corrosion resistance.
