一、问题和分歧最近三十多年来,由于航空、造船、发电等工业的不断发展,对燃气轮机的生产和发展起了推动作用。为了提高燃气轮机的效率而提高工作温度,使燃气轮机叶片和其它接触燃气的部件的腐蚀问题日益突出。这种腐蚀在760～1000℃的范围内特别严重,常称之 I. Problems and Disagreements In recent thirty years, due to the continuous development of aviation, shipbuilding, power generation and other industries, the production and development of gas turbines have played a catalytic role. In order to increase the efficiency of the gas turbine and increase the working temperature, the corrosion problems of the gas turbine blades and other parts in contact with the gas are becoming increasingly prominent. This corrosion is particularly serious in the 760 to 1000 ℃ range, often called
