Characterisation of a metal matrix composite produced with laser particle injection

This paper concentrates on the laser particle injection process. TiC, TiN end SiC particles were injected into Ti-6Al-4V, which resulted in the formation of a metal matrix composite with modest dissolution of the added particles. The laser tracks with SIC exhibited a diversity of microstructures with high hardness. Slight changes in the conditions of injection process, substantially influenced the microstructure of the modified layer. Abrasive wear experiments were performed to examine the modified layer.
