调制比对MoS_2-Ti/Cu-Ni-In多层膜微动磨损性能影响
|
摘要
为了改善钛合金表面的抗微动磨损性能,采用非平衡磁控溅射技术在钛合金(TC4)表面沉积了不同调制比(2∶1、1∶1、1∶2)的MoS_2-Ti/Cu-Ni-In多层固体润滑膜(调制周期均为2μm)。利用扫描电镜、划痕仪、XRD、维氏显微硬度计、微动摩擦磨损试验机、3D表面轮廓仪对多层膜的形貌、结合力、物相、硬度、抗微动磨损性能、磨痕形貌进行分析测试。结果表明,所制备的MoS_2-Ti/Cu-Ni-In多层膜交替结构清晰,结构致密,在12000个微动循环周期后,测得MoS_2-Ti/Cu-Ni-In多层膜在调制比为工艺2∶1、1∶1时,多层膜的室温平均微动系数分别为0.071、0.065,其最终磨损总量分别为0.087mm~3、0.045mm~3,多层膜具有良好的抗微动磨损效果。
In order to improve the fretting wear resistance of titanium alloy surface,MoS_2-Ti/Cu-Ni-In multilayer solid lubrication films(modulation period is 2μm)with different modulation ratios(2∶1,1∶1,1∶2)were deposited on the surface of titanium alloy by non balanced magnetron sputtering technique.The morphology,binding force,phase,hardness,fretting wear behavior and wear scar of the multilayer films were analyzed by scanning electron microscope,scratch tester,XRD,vickers micro hardness tester,fretting wear testing machine and 3D surface profile instrument.The results shows that,MoS_2-Ti/Cu-Ni-In multilayer films alternating structure is clear and the structure of multilayer films is compact.After the 12000 fretting cycles,the MoS_2-Ti/Cu-Ni-In multilayer films with the modulation ratio of 2∶1 and 1∶1 were measured.The average fretting coefficient of the multilayer films at room temperature is 0.071 and 0.065,the wear amount was 0.087 mm~3 and 0.045 mm~3.The multilayer films has excellent anti-fretting wear effect.
