Microstructure and wear properties of laser clad TiCo/Ti2CO intermetallic coatings on titanium alloy

摘要

Wear resistant TiCo/Ti2Co dual-phase intermetallic coatings were fabricated on a titanium alloy by laser cladding, Microstructure of the coatings consists of isolated irregular block-like TiCo primary phase in the Ti2Co matrix. The coatings have high hardness and excellent abrasive and adhesive wear resistance under dry sliding wear test conditions. (c) 2004 Elsevier B.V. All rights reserved.
