Process for coating hollow internally cooled gas turbine blades with adhesive-, zirconium oxide ceramic- and Cr diffusion layers useful in gas turbine engine technology has adhesive layer applied by plasma or high rate spraying method

摘要

Process for coating hollow internally cooled gas turbine blades (1) where the blade base material (3) on the outer blade side has an external coating (5) consisting of an adhesive layer (6) based on MCrAlY and a heat insulating Zr oxide ceramic layer (9), and a Cr diffusion layer (7) on the inner side of the blades. An independent claim is included for a gas turbine blade as described above.
