Abstract
The present invention relates to a process for producing a diffusion layer for protecting temperature-stressed components, in particular of turbomachines, against oxidation and corrosion. The process comprises application of at least one slip to a component surface on which the diffusion layer is to be produced, and drying and/or hardening of the at least one slip by a heat treatment at a first temperature and diffusion heat treatment at a second temperature. The slip comprises Al-containing powder, Si-containing powder and a binder and also a Cr-containing powder which does not comprise any hexavalent chromium. In addition, the invention provides a corresponding slip.
