Liquid Phase Surface Treatment of Ti-6Al-4V Titanium Alloy Pre-Sprayed with TiC/Ni Using Pulsed Nd-YAG Laser

Abstract:

In the present work Ti-6Al-4V titanium wrought alloy was initially sprayed with TiC-15 wt% Ni powder, before being liquid phase surface treated by pulse Nd-YAG laser. Microstructure, chemical composition and phase analysis and hardness of the treated layers were studied by using field emission scanning electron microscope (FE-SEM), energy dispersive spectrometer (EDS), X-ray diffraction analysis (XRD) and micro-hardness test respectively. The result showed that the treated layers had ultrafined dendritic structure containing nanosize TiC particles and their hardness were as high as 982 HV_0.03 respect to 350 HV_0.03 for the base material.
