Y15钢表面沉积TiN、TiCN和AlTiCrN涂层的摩擦磨损性能
|
摘要
为提高Y15易切削钢的耐磨性能,对Y15钢试样表面进行离子氮化处理,并分别采用TiN、TiCN、AlTiCrN进行镀膜处理。在SRVⅣ磨损试验机上考察制备的3种试样的摩擦磨损性能,并与盐浴渗氮处理试样进行比较。结果表明:3种离子渗氮+涂层处理试样中,离子渗氮+AlTiCrN涂层的耐磨性最好,其次是离子渗氮+TiCN涂层和离子渗氮+TiN涂层;盐浴渗氮试样的磨损机制主要为黏着磨损,离子渗氮+TiN涂层试样的磨损机制以黏着磨损和磨粒磨损为主,其他2种试样的磨损机制主要为轻微犁沟和黏着磨损。
In order to improve the wear resistance of free cutting steel Y15,the surface of steel Y15 was treated with ion nitriding and the coatings( TiN,TiCN,AlTiCrN coating) by multi-arc ion plating technique. The tribological properties of the samples prepared was studied on a SRVⅣoscillating friction and wear tester,and were compared with those of salt bath nitriding samples. The results show that the sample with ion nitriding + AlTiCrN coating has the best wear resistance,then following by that with nitriding + TiCN coating and nitriding + TiN coating. The main wear mechanisms are adhesive wear for the sample treated with salt bath nitriding,adhesion wear and abrasive wear for the sample treated with ion nitriding +TiN coating,and slight furrow and adhesion wear for the samples treated with ion nitriding + TiCN coating and nitriding +AlTiCrN coating,respectively.
