Abrasive wear resistance of detonation coatings from mechanochemically alloyed Ti–Al–B powders

The paper examines the abrasive 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 hi...

Description
Summary:The paper examines the abrasive 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 characteristics. 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.
