摘要
目的替代电镀硬铬在航空业中的应用,拓展新的耐磨涂层制备工艺。方法通过多弧离子镀工艺在多种基材上制备TiCN膜层,系统研究膜层的耐蚀性能、耐磨性能、结合力等性能。结果4130钢与带离子镀TiCN膜层的4130钢试样组成的电偶对,电偶腐蚀敏感性高(为严重的E级);TC4钛合金与带离子镀TiCN膜层的TC4钛合金试样组成的电偶对,电偶腐蚀敏感性不高(为不严重的B级);TiCN镀层在钛合金、4130钢和30CrMnSiA钢基体上的结合强度分别为30~35 N、15~20 N和15~20 N。结论采用TiCN膜层保护4130钢构件时要重视对TiCN膜层缺陷的控制,采用离子镀TiCN膜层保护TC4钛合金构件不存在显著的电偶腐蚀;多弧离子镀TiCN膜层的耐磨性能较差,不能有效提高TC4钛合金和30CrMnSiA钢的耐磨性能。
In order to replace the application of electroplated hard chromium in the aviation industry,the work aims to develop new wear-resistant coating preparation processes.TiCN coatings were prepared on various substrates through multi arc ion plating technology.The corrosion resistance,wear resistance,adhesion and other properties of the coatings were systematically studied.The thermocouple pair composed of 4130 steel and 4130 steel samples with ion coated TiCN coating had high sensitivity to galvanic corrosion(severe grade E).For the thermocouple pair composed of TC4 titanium alloy and TC4 titanium alloy samples with ion coated TiCN coating,the sensitivity of thermocouple corrosion was not high(grade B,which was not severe).The bonding strength of TiCN coating on titanium alloy,4130 steel,and 30CrMnSiA steel substrates was 30-35 N,15-20 N,and 15-20 N,respectively.When TiCN coating is used to protect 4130steel components,attention should be paid to controlling the defects of TiCN coating and ion plating TiCN coating can be used to protect TC4 titanium alloy components from significant galvanic corrosion.The wear resistance of TiCN coating by multi arc ion plating is poor,so the coating cannot effectively improve the wear resistance of TC4 titanium alloy and 30CrMnSiA steel.
