Effects of Doping of Composite Ti–TiC Coatings with Transition and Valve Metals on Their Structure and Mechanical Properties

详细

This study presents the results of an examination of the mechanical properties and structure of wear-resistant composite Ti–TiC-based coatings, which were formed on commercially pure titanium by electric-arc processing in an aqueous electrolyte, with transition and valve metals (Al, Ni, Cr, and Si) introduced into their composition. This study demonstrated that the change in mechanical properties can be attributed to the formation of the martensitic phase at the titanium–TiC interface, which is induced by hardening phenomena associated with electric-arc processing.
