Abstract
A process for forming a diffusion coating on a substrate is disclosed, including preparing a slurry including a donor metal powder, an activator powder, and a binder, and applying the slurry to the substrate. The slurry is dried on the substrate, forming a slurry layer on the substrate. A covering composition is applied over the slurry layer, and the covering composition is dried, forming at least one covering layer enclosing the slurry layer against the substrate. The slurry layer and the at least one covering layer are heated to form the diffusion coating on the substrate, the diffusion coating including an additive layer and an interdiffusion zone disposed between the substrate and the additive layer.
