Improving tribological properties of Ti-Zr alloys under starved lubrication by combining thermal oxidation and laser surface texturing

In efforts to improve the tribological properties of the Ti-Zr alloy, thermal oxidization (TO) and laser surface texturing (LST) were performed on the surfaces of the alloy. Four kinds of samples, i.e., TO combined LST (TOLST), TO without LST (TO-only), LST without TO (LST-only) and annealed-only (Contrast) samples were prepared. The tribological properties of the samples were investigated by carrying out sliding wear tests under starved lubrication using a ball-on-disc tribometer. The results show that TO treatment significantly improves the tribological properties of the surfaces due to the formation of the ZrTiO4 layer which has a higher hardness and better wettability with PAO4 oil. More interestingly, the synergistic effect of TO-layer and LST can further improve the tribological properties since the dimple-textures can exist for a long time and offer effective lubrication for the contract areas.
