| 摘要 |
The invention discloses a process for coating a base material (1) which is subject to friction with a protective layer (2) comprising MCrAlY by means of a thermal spraying process. The MCrAlY is fed to an injection nozzle in powder form and is applied to the base material (1). At the same time as the MCrAlY powder, a ceramic material in powder form, such as for example Al2O3, Si3N4, SiC, AlN, Cr3C2, MoSi2 or an equivalent material, is applied to the base material (1), a diffusion heat treatment is carried out and those locations of the applied coating (3) which are subject to friction are cut into a toothed or pointed shape.
