Gas turbine component and method for manufacturing the gas turbine component made of composite material with ceramic matrix.

摘要

There is a method (100) for producing a gas turbine component (110) of composite material with a ceramic matrix and a gas turbine component (110) of composite material provided with a ceramic matrix. The method includes modifying a surface (111) of the gas turbine component (110) of composite material with a ceramic matrix of producing a modified surface of (113) with a surface roughness of less than 6 micrometers. The modification is selected from the group of techniques consisting of the application of non-reinforced matrix layers on the surface, the vapor deposition of silicon on the surface, the honing of the surface, applying solder paste to the surface, and combinations thereof. The component (110) includes a modified surface (113) having a surface roughness of less than 6 micrometers. The modification is selected from the group consisting of a surface of the gas turbine component (110) made of composite material coated with a ceramic matrix unreinforced matrix layers, is by vapor deposition on the surface-applied silicon, a honed surface, a coated onto the surface of solder paste and combinations thereof.
