  1. 6. Oxidation behaviour of MCrAlX coatings : effect of surface treatment and an Al-activity based life criterion

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

    Sammanfattning : MCrAlY coatings (M=Ni and/or Co) have been widely used for the protection of superalloy components against oxidation and hot corrosion in the hot sections of gas turbines. The drive to improve engine combustion efficiency while reducing emissions by increasing the operation temperature brings a big challenge for coating design. LÄS MER
