摘　　要：研究了激光微织构处理后材料表面覆盖TiAlSiN涂层在脂润滑条件下的摩擦磨损性能。使用声光调Q二极管Nd:YAG激光器在TC11钛合金表面进行织构化处理。使用磁控溅射设备在织构后表面加镀覆TiAlSiN涂层。通过Rtec通用摩擦磨损试验机考察涂层织构在脂润滑条件下的摩擦磨损性能。通过加工不同密度研究织构形貌参数对摩擦性能的影响。研究结果表明:在室温滑动摩擦条件下TiAlSiN涂层能够保护基体减小磨损,表面织构能够进一步减小摩擦系数。在织构密度为30%时摩擦系数最小。Studied the tribology performance of TiAlSiN coated and laser textured surface under grease lubrication.TC11 surface was textured by Nd:YAG laser.The tribology performance of samples was measured by Rtec tribometer after using magnetron sputtering to process TiAlSiN coating.The study find that textured TiAlSiN coating can protect TC11 substrate from surface wear and reduce friction coefficient.Samples get minimum friction coefficient under 30%texturing density.
