Abstract
A wear protection coating, in particular an erosion protection coating for gas turbine components is disclosed. The wear protection coating is applied to a to-be-protected surface of a flow mechanically stressed component. The wear protection coating has an at least double-layer structure, where a first layer is applied to the to-be-protected surface of the component and has a material composition that is adapted to the material composition of the component and where a second layer forms an outer cover coat.

A wear protection coating, in particular an erosion protection coating for gas turbine components, which is applied to a to-be-protected surface of a flow mechanically stressed component, comprising an at least double-layer structure, wherein a first layer is applied to the to-be-protected surface of the component and has a material composition that is adapted to a material composition of the component, and wherein a second layer forms an outer cover coat.
A component, in particular a gas turbine component, with a wear protection coating, in particular with an erosion protection coating, which is applied to a to-be-protected surface of a flow mechanically stressed component, wherein the wear protection coating has an at least double-layer structure, wherein a first layer is applied to the to-be-protected surface of the component and has a material composition that is adapted to a material composition of the component, and wherein a second layer forms an outer cover coat.
A method to manufacture a wear protection coating, in particular an erosion protection coating for gas turbine components, which is applied to a to-be-protected surface of a flow mechanically stressed component, comprising the steps of:
- a) making available the component comprised of a component material composition;
- and
- b) applying the wear protection coating to the to-be-protected surface of the component, wherein the wear protection coating has an at least double-layer structure, wherein a first layer is applied to the to-be-protected surface of the component and has a material composition that is adapted to a material composition of the component, and wherein a second layer forms an outer cover coat.
A gas turbine component, comprising:
- a surface;
- and
- a wear protection coating applied to the surface, wherein the wear protection coating includes a first layer in contact with the surface and having a material composition that is adapted to a material composition of the surface, and a second layer applied to the first layer that forms an outer cover coat on the component.
A method for wear protecting a component of a gas turbine, comprising the steps of:
- applying a wear protection coating to a surface of the component, wherein the wear protection coating includes a first layer in contact with the surface and having a material composition that is adapted to a material composition of the surface, and a second layer applied to the first layer that forms an outer cover coat on the component.
