Wear Resistance of Detonation Coatings from Mechanochemically Synthesized Ti–Al–B Powders

Abstract

The paper examines the wear resistance of composite detonation coatings with different structures based on Ti–Al–B, Ti–Al–B–O, and Ti–Al–B–N systems. It is established that the coating consisting of an intermetallic matrix and solid-phase inclusions as titanium borides and oxides has the highest indicators. The coating whose microstructure is based on a random two-phase mixture of relatively soft intermetallic and nitride phases and whose hard component is represented only by borides has the lowest wear resistance.
