Abstract

A turbomachine component of a stationary turbomachine includes a substrate made of high alloyed 10% to 18% chromium steels or titanium alloys or nickel base alloys or cobalt base alloys with a substrate surface and an erosion and corrosion resistant coating system. The coating system includes a first layer, which is deposited on the substrate surface of the turbomachine component and acts as a corrosion resistant layer and a second layer. The second layer is deposited on the first layer and acts as an erosion resistant layer, wherein the first layer is a Zr single layer and the second layer is a W/WC multilayer.
