高温合金的高温腐蚀是一种很复杂的高温环境(气、液、固相)与合金(固相)界面上发生的物理—化学—机械的交互作用现象。在不同环境中镍、钴、铁基合金中的合金化元素呈现出不同效果,由于机理尚未搞清,因此不同试验结果间的很大差异不易解释。国外正积极从事研究,试图得到一个解释高温腐蚀的统一“模型”。 The high temperature corrosion of superalloys is a complex physical-chemical-mechanical interaction occurring in the high temperature environment (gas, liquid, solid phase) and alloy (solid phase) interface. Alloying elements in nickel, cobalt, and iron-based alloys exhibit different effects in different environments. Because the mechanism has not yet been clarified, the large differences between the different test results are not easily explained. Foreign countries are actively engaged in research, trying to get a unified model to explain the high temperature corrosion.
