摘　　要：采用真空电弧镀在TC11钛合金上沉积ZrN涂层,固体颗粒冲蚀实验研究不同冲蚀颗粒、冲蚀速度、冲蚀角度对涂层抗冲蚀性能的影响,并用SEM观察表面及断面形貌。结果表明,在相同冲蚀条件下,ZrN涂层冲蚀率随冲蚀颗粒硬度、冲击角度及冲蚀颗粒速度的增加而增加,冲蚀角度为90°时,ZrN涂层冲蚀速率最大,ZrN涂层提高了TC11钛合金的抗冲蚀性能。ZrN coating was deposited on TC11 substrate by multi-arc plating, erosion resistance of ZrN coating was evaluated by solidparticle erosion testing using differential particles at differential impact angle and impact velocity, the surface and cross-sectional microscopy were examined in a scanning electron microscopy （ SEM ）. It was found that the erosion rate of ZrN coating was increasing with particles hardness, impact angle and impact velocity under the same impact condition, ZrN coating had the maximum erosion at 90° impact angle, ZrN coating demonstrated markedly improvement in erosion resistance performance of TC11 titanium alloy.
