A protection coating is vacuum plasma sprayed onto a substrate by forming an adhesion layer, and intermediate layer and a cover layer. The adhesion layer is made from a material whose chemical composition and thermal expansion coefficient essentially correspond to those of the substrate. The intermediate layer is made up of a mixture of the materials of the adhesion layer and the cover layer and is essentially a transition area gradually passing from 100% adhesion material to 100% cover layer. The latter is made of a refractory material in the form of an oxide, boride, carbide and nitride. |
