Abstract: In order to improve the friction and wear performance of TiZr-based alloy Ti-20Zr-6.5Al-4V (referred to as T20Z), plasma arc cladding technology was used to generate in-situ nitride reinforced titanium alloy composite coatings on the surface of T20Z alloy through synchronous powder feeding at different nitrogen flow rates (300, 350, 400, 450 L/h). The microstructure, phase composition, hardness, and friction and wear properties of the coatings were analyzed and characterized by metallographic microscopy, X-ray diffractometer (XRD), Vickers hardness tester, UMT-2 multifunctional tribometer, three-dimension profilometer, and scanning electron microscope (SEM). The results show that the nitride reinforced titanium alloy composite coatings with excellent metallurgical bonding with the substrate can be obtained by nitrogen flow rate cladding at 300—450 L/h, where the substrate phase is α phase, and the reinforcing phases are TiN0.3 and TiN. As the nitrogen flow rate increases, the TiN0.3 phase increase continuously, and the hardness of the coatings gradually increases. When the nitrogen flow rate reaches 450 L/h, the TiN diffraction peak begins to appear, and the hardness has a maximum value of 1 036HV0.2, which is 640HV0.2 higher than the substrate. Compared with the untreated samples, the wear resistance of the coatings has been improved, and with the increase of nitrogen flow rate, their wear resistance shows a trend of first increasing and then decreasing. The most obvious change is when the load is 10 N and the nitrogen flow rate is 400 L/h, with an increase of 46.08% in wear resistance. The wear mechanism of the coatings gradually changes from severe abrasive wear of the untreated samples to mild abrasive wear and local adhesive wear.
