Study of Abrasive Wear Resistance of Detonation Coatings Made of Mechanically Alloyed Powders Ti-Al-B

摘要

Abrasive wear resistance of detonation composite coatings Ti-Al-B of different structures is studied. It is found that the coating having an intermetallide matrix with solid-phase inclusions of titanium boride and oxides exhibits the best characteristics. The coating with microstructure based on an occasional mixture of comparatively soft intermetallide and nitride phases with the solid component represented only by borides has the lowest abrasive wear resistance.
