Abstract

Laser surface alloying with TiC powder pre-coatings or laser surface carbonization is utilized to modify the wear resistance of a (gamma) -TiAl intermetallic alloy Ti-48Al- 2Cr-2Nb. An `in-situ' wear resistant composite coating reinforced by rapidly solidified TiC dendrites is made on substrate of the (gamma) -TiAl intermediate alloy. Crack-free TiC/TiAl composite coatings in thickness up to 1.6 mm, can be produced by laser surface alloying with preheating and slow post-treatment cooling. The hardness and wear resistance under dry sliding wear conditions are remarkably increased after the laser surface carbonization treatment of the (gamma) -TiAl intermetallic alloy.
