Provided is a coating system for a substrate, the system including a first, second and third layer. In the system, the first layer is designed as an adhesion promoter layer, the second layer is a ductile metal layer with a columnar structure and the uppermost, third layer is a ceramic oxide layer with a high hardness value. The substrate is ideally an element of a compressor component of a stationary gas turbine. Also disclosed is a method for producing the coating system.

Contour-following protective layer for compressor components of gas turbines

A turbomachine component having a main body and a multilayer coating, which is applied directly to the main body is provided. The multilayer coating is at least 5 &#x3bc;m and at most 35 &#x3bc;m thick and has a plurality of layers applied directly one on top of the other, wherein the layer applied directly to the main body is an adhesion promoting layer, which comprises chromium nitride, and at least one of the remaining layers comprises a hard material.

Turbomachine component having a functional coating

A method for applying a wear protection layer to a continuous flow machine component which has a base material comprising titanium is provided. The method includes the following steps: mixing a solder which comprises an alloy comprising titanium and particles which are distributed in the alloy and have a reaction agent; applying the solder to predetermined points of the continuous flow machine component; introducing a heat volume into the solder and the continuous flow machine component so that the alloy becomes liquid and the reaction agent changes through diffusion processes with the solder and undergoes a chemical reaction with the alloy, forming a hard aggregate; and cooling the solder so that the alloy becomes solid.

Method for applying a wear-resistant layer to a turbomachine component

The invention relates to a component having a coating system, which comprises at least one bonding coat applied directly onto the component and at least one thermal barrier coat formed on the bonding coat, the bonding coat comprising from 22 to 36 wt. % Cr, from 15 to 30 wt. % Ni, at most 55 ppm Al, and Fe as a basis.

Component having a coating system

There are described components of a steam turbine, comprising a thermally insulating layer and a metallic anti-erosion layer on said thermally insulating layer. The anti-erosion layer is provided with the same material as the metallic connecting layer.
