Frictional wear resistance of the composite layers based on intermetallic phases of the Ti-Al system produced on the two phase Ti6Al2Cr2Mo titanium alloy

Alloys of the intermetallic phases from the Ti-Al system belong to the group of new materials with unique physical, chemical and mechanical properties. Unfortunately, their liability to brittle fracture and their poor plasticity greatly restrict their practical application range. To obviate these drawbacks, these materials are produced in the form of layers on the surface of metallic materials. The paper presents the results of examinations of the structure and frictional wear resistance of the TiAl intermetallic surface layers with a near-surface diffusion Al203 and AIN zone produced on the binary Ti6Al2Cr2Mo titanium alloy using a hybrid process (also known as the multiplex process) that combines the magnetron sputtering of an Al coating with the glow discharge assisted oxidation process.
