Patent

CA 2600198

The invention relates to a component, in particular a gas turbine component, comprising a base body (11) which is made of a base material and of a wear-and- tear protective coating (12) which is applied to the surface of the base body (11), in particular, a coating which protects against corrosion and/or oxidation and/or erosion. According to the invention, a blocking layer (16) is positioned between the base body (11) and the wear-and tear coating (12) in order to protect the base body (11) during a chemical or electrochemical removal of a coating of the component (10).

L'invention concerne un élément, en particulier un élément pour une turbine à gaz, comprenant un corps de base (11) en matière première de base et un revêtement (12) protégeant contre l'usure, disposé sur la surface du corps de base (11), en particulier un revêtement protecteur contre la corrosion et/ou l'oxydation et/ou l'érosion. Selon l'invention, une couche de blocage (16) est positionnée entre le corps de base (11) et le revêtement (12) de protection contre l'usure, ce qui permet de protéger le corps de base (11) lors du retrait d'une couche chimique ou électrochimique du composant (10).
