Patent ID: 8920881

Claim:
A method of producing a coated component, comprising steps: a) providing a component substrate having a substrate surface; b) applying at least two layers including at least one metallic layer and at least one ceramic layer on at least a portion of said substrate surface, one above the other, to form a protective coating being a wear-protection coating, a corrosion-protection coating or an erosion-protection coating, wherein said at least one ceramic layer respectively has a hardness greater than a hardness of said at least one metallic layer respectively, and wherein an outer surface of said protective coating facing away from said substrate is formed by at least one said ceramic layer; and c) after said step b), performing ball blasting or shot peening on said outer surface of said protective coating on said substrate surface of said component substrate, whereby energy is applied to said protective coating by said ball blasting or shot peening, and dissipating said energy in said at least one metallic layer sufficiently so as not to cause damage of said outer surface formed by at least one said ceramic layer.
