摘　　要：随着现代科学技术的快速发展,对金属材料高温服役性能的要求也越来越高,不仅要有良好的机械性能,同时还要具有较高的化学稳定性即抗高温氧化能力。实际上金属的高温氧化是一极其复杂的过程,影响这一过程的因素很多,而高温腐蚀研究又在能源、动力和石油化工等工业发展中具有重要的作用。综述了目前国内外有关Cu基合金高温氧化行为研究的现状,分析了纯金属Cu、二元单相和双相Cu基合金以及三元Cu基合金的高温氧化机制,比较了它们高温氧化行为的差异,探讨了组元间固溶度、相的组成以及添加组元等因素对合金表面形成规则、连续致密且具有保护性外氧化膜的影响机制,这些对于进一步研究合金高温氧化机理,寻找更加完善的防护措施以及发展新型耐高温材料等方面都具有重要的意义。With the rapid developmemt of moden science and technology,the metal materials at high temperatures have not noly required excellent mechanical properties,but also good high temperature chemical stability.Actually,high temperature metal oxidation is a very complex course and there are many factors that can affect this course,while studies on high temperature corrosion play an important role in energy,power and petrochemical fields.This paper summaries current research situation of high temperature chemical stability for Cu-based alloys.High temperature oxidation mechanisms of metal Cu,binary single and duoble phase Cu-based alloys as well as ternary Cu-based alloys are analyzed.The differences of oxidation behavior among them are compared and the effects of the mutual solubility of components,phase composition and adding component on the formation of regular,continuous and protective scales are disscussed.These are very important for further studying high temperature oxidation mechanism of multi-component alloy,looking for protection methods of alloys and developing novel and high temperature resisting materials.
