Laser Surface Melting of Ti₆Al₄V Alloy with Ti-BN-C Mixed Powders

Abstract:

Laser surface melting was carried out on the surface of Ti-6Al-4V alloy with Ti-BN-C mixed powders. In this paper, an influence of the mole ratio of BN/ C on microstructure, chemical composition, element distribution and hardness were separately analyzed by scanning electron microscope (SEM), X-ray diffraction (XRD), electron probe micro-analyzer (EPMA) and Vickers hardness test (HV). The results showed that the melting layer mainly consisted of TiC_xN_1-_x (x=0, 0.3, 0.7), TiB and Ti. The hardness was increased with improving the mole ratio of BN/C ratio.
