Mechanical and Tribological Properties of γ-TiAl-Based Coatings Produced by the Laser Cladding Technology

Abstract:

Coatings from the γ-TiAl-based powder characterized by enhanced microhardness compared to that of titanium substrates were produced by the laser cladding technology. In the current paper wear mechanisms of substrates and coating materials under sliding friction conditions are described in detail. The wear of the substrate material was due to the seizure mechanism related to the mass transport of a considerable volume of the specimen material and a steel indenter. Only shallow notches without any mutual mass transport signs were observed on the coating surface after a sliding friction test.
