摘　　要：高温高压水是轻水核反应堆冷却系统的主要服役环境,反应堆压力容器、管道及蒸汽发生器等构件材料在高温水中的环境损伤是影响核电安全的重要因素.材料在高温水中形成的腐蚀产物膜是影响其服役稳定与环境失效的关键.本文介绍了高温高压水环境中不锈钢和镍基合金腐蚀产物膜的形貌、结构、影响因素及形成机制,并对当前研究中存在的主要问题进行了讨论.The coolant system of light water reactor works under the condition of high-temperature and high-pressure water. Environmental damage of components in light water reactor （LWR） in high-temperature water is an important factor that impacts nuclear safety. The corrosion scale formed in high-temperature water plays a key role for the stable service and environmental failure of materials. In the present work, the morphology, structure, influence factors and formation mechanism of corrosion scales formed on stainless steels and nickal based alloys in high-temperature water were introduced. The main problems existing in current studies were also discussed.
