摘　　要：压水堆压力容器、管道、蒸汽发生器等结构材料在高温高压水环境中的腐蚀是影响核电站安全的重要因素,金属表面的氧化膜是影响其服役稳定与环境失效的关键,在含锌和钠离子的高温水溶液中制备了镍600合金的表面氧化膜,通过Mott-Schottky法分析了氧化膜的半导体性质,结合氧化膜制备前后镍600合金的质量指标,表明镍600合金在含锌的高温水溶液中表现出更好的耐蚀性。The corrosion of pressure vessels, pipelines, steam generators and other structure materials in pressurized water reactor （PWR） in high temperature and high pressure water is an important factor that affects the safety of nuclear power plants. The oxide films on the metal surface play a key role for the stable service and environmental failure. Oxide films on alloy 600 were prepared in high temperature water containing Zn2＋ and Na＋. Semiconductor properties of the oxide films were analyzed using Mott-Schottky method and mass index before and after the preparation of oxide films. The results indicated that the alloy 600 showed better corrosion resistance in high temperature water solution containing zinc.
