目的提高锆合金在高温高压环境中耐动水腐蚀性能。方法利用多弧离子镀技术（MAIP）在Zr-4合金表面分别制备了Al2O3涂层和Cr/Ti AlN复合涂层,利用磁控溅射技术（MS）在Zr-4合金表面制备了Ti N涂层。通过堆外高压釜实验,对比研究了三种不同涂层的耐高温高压动水腐蚀性能,利用自动划痕仪检测膜基结合力,利用XRD分析涂层的物相成分,利用SEM观察涂层腐蚀前后的微观形貌,利用EDS对涂层元素种类与含量进行分析。结果多弧离子镀技术制备的Al2O3涂层和Cr/Ti Al N涂层致密度较高,但表面存在少量大颗粒与微孔洞;磁控溅射技术制备的Ti N涂层均匀平整,表面大颗粒较少。Al2O3涂层、Ti N涂层和Cr/Ti Al N涂层可...

The work aims to improve the resistance to dynamic water corrosion of zirconium alloy in high temperature and high pressure environment. Oxide-coated Al_2O_3 and composite coating Cr/TiAlN were prepared on the surface of Zr-4 alloy by multi-arc ion plating (MAIP). Nitride coating TiN was prepared on the surface of Zr-4 alloy by magnetron sputtering (MS). The high temperature and high pressure hydrodynamic corrosion performance of three different coatings were compared by autoclave experiments. The adhesion of the film base was detected by automatic scratch tester. The phase composition of the ...
