对金属材料的热腐蚀机理及危害进行了探讨。在对不同热腐蚀评价方法对比分析的基础上，以某发动机涡轮工作叶片和导向叶片及其所用材料为研究对象，采用燃气热腐蚀试验方法，开展涡轮零部件及材料抗热腐蚀能力评价方法的研究。结果表明，该方法是最为接近海洋环境下涡轮零部件实际工作状态的实验室评价方法，适合于评价涡轮零部件及材料的抗热腐蚀性能，能为改进涡轮零部件的防腐设计和防腐加工工艺提供较为客观、准确的试验评价依据。
In the present investigation, the mechanism and hazard of hot corrosion for metal materials were reviewed. Based on analyzing laboratory testing techniques of hot corrosion, turbine blades and vanes of some gas turbine engine were introduced to study the evaluating method for hot corrosion resistance capability of turbine components and materials with burner-rig test. It was shown that burner-rig test was competent for evaluating hot corrosion resistance of gas turbine components and materials. It should be the most efficient method on evaluating marine environment hot corrosion resistance of gas turbine components and materials in laboratory so far, and the objective authorities of anti-corrosion designing and processing could be provided by this kind of test method.
