摘要
磁控溅射与电弧离子镀复合技术结合了2种镀膜方法的优点,制备的涂层性能优良,采用此法在SUS304表面制备了TiAlSiN-TiAlAgN-Ti(Mo)N/MoS2纳米复合涂层。采用SEM、EDS、XRD、显微硬度计、高温磨损试验机等研究了纳米复合涂层的微观结构、硬度、在室温(RT)、200℃、400℃、600℃恒温以及RT^600℃、600~200℃变温条件下的摩擦磨损性能。结果表明:TiAlSiN-TiAlAgN-Ti(Mo)N/MoS2纳米复合涂层表面较粗糙,有较多熔滴,显微硬度为22.56 GPa;由于MoS2、Ag以及Al2O3、SiO2分别在室温、中温(300~400℃)及高温下具有一定的润滑效果及协调润滑作用,涂层在恒温和变温环境下均具有良好的耐磨性能。
Magnetron sputtering and cathode arc composite technology combined the advantages of the two methods,which could prepare excellent coatings.TiAlSiN-TiAlAgN-Ti(Mo)N/MoS2 nanocomposite coatings were prepared on SUS304 surface by this composite technology.The microstructure,hardness,friction and wear properties of TiAlSiN-TiAlAgN-Ti(Mo)N/MoS2 nanocomposite coatings at different constant temperature including room temperature(RT),200℃,400℃and 600℃and at variable temperatures of RT-600℃and 600-200℃were studied by means of SEM,EDS,XRD,microhardness tester and high temperature wear tester.Results showed that the surface of TiAlSiN-TiAlAgN-Ti(Mo)N/MoS2 nanocomposite coatings was rough with more droplets,and the microhardness was 22.56 GPa.Because MoS2,Ag,Al2O3 and SiO2 possessed a certain lubrication effect and coordination lubrication effect at room temperature,medium temperature(300-400℃)and high temperature respectively,the as-obtained coatings had good wear resistance at constant and variable temperatures.
