METHOD FOR APPLYING A HIGH-TEMPERATURE STABLE COATING LAYER ON THE SURFACE OF A COMPONENT AND COMPONENT WITH SUCH A COATING LAYER

摘要

The invention proposes a method for applying a high-temperature stable coating layer (12) on the surface of a component (11), comprising the steps of: a) providing a component (11) with a surface to be coated; b) providing a powder material containing at least a fraction of sub-micron powder particles (18); c) applying said powder material to the surface of the component (11) by means of a spraying technique to build up a coating layer (12), whereby d) said sub-micron powder particles (18) are each at least partially surrounded by an oxide shell (20) and establish with their oxide shells (20) an at least partially interconnected sub-micron oxide network (22) within said coating layer (12).
