Tribological properties and microstructures of Al2O3-TiC-TiB2 reinforced composites

Ti-3Al-2V alloy is an important aviation material but shows poor resistance to slid wear. Laser cladding of the Fe3Al-B4C pre-placed powders on a Ti-3Al-2V substrate can form the TiC-TiB2 reinforced composites, which improved the wear resistance of the substrate. In this study, it was noted that the...
