Abstract
High temperature blades are the core eomponents of aero engines and gas turbines. However, the Oxidation and corrosion damage of high temperature blades during Service are key issues that affacting their reliable Service. By preparing aluminized coatings on the surfaces of the blades, the Oxidation resistance and corrosion resistance of the blades can be significantly improved. In this paper, the issues relating to the preparation, Service and Performance improvement of aluminized coatings were summarized. Firstly, the current main preparation technologies of aluminized coatings and the formation mechanisms of the coatings were introduced. Secondly, the high temperature Oxidation and corrosion mechanisms of the aluminized coatings were elaborated. Subsequently, the current element modification treatments and the effeets of the modifi-cation chemical elements used to improve the Oxidation resistance and corrosion resistance of the aluminized coatings were summarized. Finally, the development trend of aluminized coatings in the future was prospected. Besides, the technology of preparing large - grain oxide film by pretreatment proposed in this paper would provide a reference for the development of high - Performance aluminized coatings in the future.
