为了研究磁控溅射(MS)和多弧离子镀(MAIP)技术制备Cr涂层的高温抗氧化性能,分别在锆合金表面制备厚度约5 μm的Cr涂层.利用氧化动力学曲线对比研究800 ℃条件下涂层的高温抗氧化性能,利用SEM、XRD、 EDS分析涂层表面形貌和相结构.结果表明:磁控溅射和多弧离子镀Cr涂层均能显著提高锆合金的高温抗氧化性能;磁控溅射Cr涂层表面光滑、致密,但涂层表面存在一定数量的孔洞,占涂层表面积0.40%,氧化7 h后涂层表面出现裂纹,单位面积氧化增重6.434 mg/cm~2;与磁控溅射Cr涂层相比,多弧离子镀Cr涂层不再有(211)单一择优取向,Cr涂层厚度均匀,表面平整,膜/基界面分明,孔洞相对较少,占涂层表面积0.21%,氧化7 h...

In order to study the high temperature oxidation resistance of Cr films deposited using magnetron sputtering (MS) and multi-arc ion plating (MAIP) methods, Cr films with a thickness of approximately 5 μm were deposited on the surface of zirconium alloy through different methods. The oxidation kinetics curve was used to compare the high temperature oxidation resistance of the coating at 800℃. Microstructure and phase structure of the films were investigated by SEM, XRD and EDS, respectively. The results show that the high temperature oxidation resistance of zirconium alloys is signific...
