对Zr-4合金表面分别进行多弧离子镀TiAlSiN涂层和TiAlN涂层。利用扫描电镜对涂层进行表面微观形貌观察;利用ImageJ对涂层大颗粒分布进行统计和分析;利用X射线衍射仪对涂层进行物相分析;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试样进行800℃高温抗氧化实验。结果表明:TiAlSiN涂层表面的大颗粒数较TiAlN涂层的少。TiAlSiN涂层中除了与TiAlN涂层共同拥有的Ti_2N、Ti_3AlN物相外,还生成了AlN物相和非晶相Si_3N_4。由于Si元素的加入引起残余应力,TiAlSiN涂层的膜基结合力低于TiAlN涂层。TiAlSiN涂层试样的氧化增重远低于TiAlN涂层的氧化增重。

TiAlSiN coating and TiAlN coating were deposited on Zr-4alloy surface by multi-arc ion plating, respectively.Surface micromorphology of the coatings were observed by scanning electron microscope.Statistics and analysis of the large particle distribution of the coatings were carried out by ImageJ.The phase composition of the coatings was analyzed by X-ray diffractometer.The mechanical properties of the coatings were tested by an automatic scratch tester.And the samples were subjected to 800℃high temperature oxidation resistance test in a high t...
