Title: Properties of titanium based hard coatings deposited by the cathodic arc method II. Mechanical, anticorrosive and wear resistance characteristics

Abstract: Ti based hard coatings (TiN, TiC, Ti(C,N)), single or multilayer structured, were deposited on different types of substrates (plain carbon steel, stainless steel, high-speed steel, cemented carbide) in a cathodic arc device. Vickers microhardness measurements, Calotest procedure, scratch tests, corrosion, milling and drilling tests were used to analyze some mechanical, anticorrosion and wear resistance characteristics of the films. The study of the influence of the main deposition parameters (reactive gas pressure, substrate bias, arc current) on the film properties was carried out in order to optimize the reactive cathodic arc deposition process.

Keywords: hard coatings; cathodic arc; microhardness; adhesion; wear resistance
