The wear behaviors of Ti6Al4V and laser-clad TiNiZrO2 composite coatings were studied by considering the effect of different applied loads (5, 15, 25 and 35 N) in dry and wet conditions. The studies were performed on a ball-on-disk tribometer. The micro-hardness of the clad layers was calculated. The surface morphology and the composition of the coatings were characterized by Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy (EDX), respectively. The results show that TiNiZrO2 composite coatings exhibited high micro-hardness, low friction coefficient and high wear resistance compared with Ti6Al4V alloy under similar experimental conditions. The microstructural changes due to ZrO2 additions played a significant role in the wear performance of the laser-clad TiNi alloy.
