Abstract

The present invention relates to a slip for producing an aluminum diffusion layer which comprises an Al-containing powder and an Si-containing powder and a binder, the slurry further comprising an Al-containing powder the powder particles of which are coated with Si. The invention further relates to a process for producing an aluminum diffusion layer, comprising the following steps: providing a slurry according to any one of the preceding claims, applying the slurry to a component surface on which the aluminum diffusion layer is to be created, drying and/or curing by way of a heat treatment at a first temperature, and diffusion annealing at a second temperature.
