An abrasive coating is formed on the tip of a component of a drive unit for abrading an abradable coating during a stripping operation by thermal spraying a ceramic layer on the component, the ceramic layer being profiled and providing a succession of abrading edges and intermediate spaces between the abrading edges to take up and remove abraded material. The abrading edges can be formed as deposits of ceramic material on the component or, as a ceramic layer applied on a profiled surface etched on the component.

A structural component of metal is protected against titanium fires that can be caused by flying and burning titanium droplets, e.g. in a propulsion unit. The protection against titanium fires of metal structural components is provided by a surface coating made of ceramic fibers embedded in a matrix material of a high temperature lacquer having dispersed therein aluminum powder as a filler material. The high temperature resistant lacquer is formed of silicates as a vehicle in which the aluminum powder is dispersed.

A method for manufacturing an integrally bladed rotor (10), in particular for a gas turbine, including the following method steps: preparing a rotor base member (12) having at least one first weld surface (16) and one blade (14) having a second weld surface (18); positioning the rotor base member (12) and the blade (14) in such a way that a join zone (20) is formed between the first and second weld surface (16, 18); and filling the join zone (20) with metal powder (24) and the laser welding or electron beam welding of the metal powder (24). An integrally bladed rotor (10) has a join zone (20) between the rotor base member (12) and blades (14), the join zone (20) being filled with welded metal powder (24).
摘要:
A thermal barrier layer for metallic components, in particular for gas turbine components which are subject to high temperatures or hot gas, is disclosed. The thermal barrier layer includes an inner contact layer and an outer top layer, where the inner contact layer is applied to a surface of the component via an adhesion-promoting layer that is disposed therebetween, and between the outer top layer and the inner contact layer an intermediate layer is formed.
