摘要
通过多弧离子镀与磁控溅射结合工艺在20Cr13表面分别制备CrN、TiN、TiAlCrN3种PVD涂层,研究3种涂层的摩擦磨损性能。结果表明,各类涂层均能提升基材性能,其中TiAlCrN涂层试样硬度较高(67 845 N/mm~2),CrN涂层试样薄膜结合力较高(30 N)、表面质量较优,TiN涂层试样对比另外两种涂层试样性能较差。TiAlCrN涂层试样摩擦因数较高(0.619),其硬度高、结合力好、耐磨损能力较强。在摩擦磨损试验中TiAlCrN涂层与CrN涂层表面所形成的耐磨、抛光作用的氧化膜增强了基底耐磨性能。综合考虑,TiAlCrN涂层为转子表面理想耐磨涂层。
In order to study the friction and wear properties of the coating on the rotor material surface,CrN,TiN and TiAlCrN PVD coatings were prepared on the rotor substrate 20Cr13 by the combination of multi-arc ion plating and magnetron sputtering.The test results show that the three coatings can greatly improve the performance of the substrate,among which CrN coating has the best surface quality,the highest film adhesion(30 N),and TiAlCrN coating has the highest hardness(67845 N/mm2).The friction coefficient of the TiAlCrN coating sample is the highest(0.619).Because of the high hardness of the TiAlCrN coating and the high film adhesion,the wear resistance is the strongest.Both the TiAlCrN coating and the CrN coating are in contact with oxygen during the friction and wear test,and the surface has formed an oxide film with certain wear resistance and polishing effects,which can play a certain role in lubrication during the friction process,enhance the wear resistance of the substrate;TiN coating has poor wear resistance due to poor film adhesion.Considering the overall performance,TiAlCrN coating is an ideal coating for strengthening the friction and wear resistance of compressor rotor surface.
