  3. 2. Performance of MCrAlX coatings : Oxidation, Hot corrosion and Interdiffusion

    Författare :Pimin Zhang; Ru Lin Peng; Xin-Hai Li; Sten Johansson; Ping Xiao; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : MCrAlY coatings (M=Ni and/or Co) are widely used for the protection of superalloy components against oxidation and hot corrosion in the hot sections of gas turbines. The drive for coating systems to bestow adequate oxidation and corrosion resistance upon the components becomes urgent as an inevitable result of the necessary improvement in engine combustion efficiency and service lifetime.
