摘要: 本文综述了有关热腐蚀机理的研究成果,着重叙述目前仍被公认的盐溶机理模型的研究进展,包括Rapp-Goto准则和金属氧化物在熔融Na_2SO_4中溶解度的实验测试。并以实验事实为依据阐述了盐溶机理模型的局限性,提出热腐蚀是依电化学机制发展的观点,依此举例说明金属和合金的热腐蚀历程。

Abstract：The results of research on hot corrosion mechanisms are reviewed ,with emphasis on the progress in studies on fluxing mechanism which is still widely accepted today. The progress includes Rapp-Goto criterion and the establishment of solubilities of metal oxides in fused Na_2SO_4. In the meanwhile, the limitation of fluxing mechanism is discussed on the basis of experimental evidences. A tentative proposal is brought forth in this paper that the development of hot corrosion follows electrochemical mechanism. A attempt is made to illustrate with examples hot corrosion processes in terms of electrochemical mechanism.
