采用多弧离子镀技术在表面经过渗氮处理的Zr4合金基体上制备TiAlSiN涂层。利用扫描电镜对涂层进行表面和截面的微观形貌观察;利用自动划痕仪对涂层的力学性能进行检测;利用高温热处理炉对涂层进行800 ℃高温抗氧化和1200 ℃高温淬火试验;利用X射线衍射仪对涂层进行物相分析。结果表明: Zr4合金渗氮处理后,涂层与渗氮层之间膜层分明,且涂层厚度均匀,涂层表面有少许大颗粒物质存在;膜基结合力约为28 N;涂层短时间内高温抗氧化性能较好;当渗氮剂量达到一定值后,会有ZrN物相生成。

TiAlSiN coating was deposited on nitrided Zr4 alloy surface by multi-arc ion plating. Surface and cross-section micromorphology of the coating were observed by scanning electron microscope. Mechanical properties of the coating were tested by an automatic scratch tester. High temperature oxidation resistance test at 800 ℃ and quenching test at 1200 ℃ of the coating were carried out by high temperature heat treatment furnace. And phases of the coating were analyzed by X-ray diffractometer. The results show that after Zr4 alloy nitrided, the fil...
