| 摘 要： | 通过挤压轮的失效形式分析,表面裂纹是引起其失效的主要原因。应用PCVD法对挤压轮(H13)进行表面改性处理,在其表面备制了一层T(iCN)涂层。通过扫描电镜观察T(iCN)涂层表面的形貌以及断口组织形貌,用EDS对其化学元素进行能谱分析,测试了T(iCN)涂层表面显微硬度和粗糙度。结果表明T(iCN)涂层中所含Ti元素的质量和原子百分比为最多,涂层界面结合良好,其表面硬度为1004HV,粗糙度为1.23μm,有利于改善其疲劳性能和延长使用寿命。

| Abstract: | Through analyzing failure mode of squeeze-wheel,it is concluded that surface crack is the main cause.Therefore a layer of Ti was deposited on the surface by PCVD method by modifying the surface.Then morphology of Ti coating the surface and fracture were surveyed by SEM,and the spectroscopy of chemical element was analyzed by EDS,as well as the microscopical hardness and roughness of the coating surface were tested.The results showed that both the mass ratio and atomic percentage of Ti in the coating were the largest with better interfaces inside the coating and the surface hardness was 1000HV with roughness being 1.23μm which was contributing to improve the fatigue properties and prolong the serviceable life of the squeeze-wheel. |
