Abstract

Laser surface alloying with both Si and SiC powder pre- coatings is utilized to improve the wear resistance of the Ti- 6Al-4V alloy. Rapidly solidified 'in-situ' composite coatings reinforced by TiC and Ti₅Si₃ phases are produced on substrate of the titanium alloy. Microstructure of the laser surface alloyed composite coatings is characterized and the wear resistance is evaluated under two-body abrasive wear condition. Results show that both the hardness and the wear resistance of the titanium alloy are considerably enhanced after laser surface alloying with Si and SiC powder pre- coatings.
