Paper Abstract

In this work formation of highly wear resistant metal matrix composites (MMC) surface layers on the titanium-based Ti- 6Al-4V alloy by means of laser dispersing of SiC powder is investigated. In the process, the substrate surface is locally melted to the depths up to about several hundreds μm by the slightly defocused high power laser beam. Simultaneously, SiC powder particles of irregular shape and average size of about 80 μm are injected into the molten material and single traces are produced. The optimal process parameter windows for the laser dispersing of SiC particles in Ti-6Al-4V substrate are searched for high power cw CO2 and disk lasers. The results for both laser sources are compared and the applicability of the CO2 laser in the treatment of Ti alloy is confirmed.
