Abstract: A method for welding two components is disclosed. In an embodiment, the method includes the following process steps. The two components are positioned such that the joining surfaces are opposite each other, at a short distance from each other. A high-frequency electrical current is conducted through the two components, heating the components at least in the region of the joining surfaces. The two components are pressed against each other such that the two joining surfaces are welded together.

Abstract: An aircraft engine comprising a compressor and at least one turbine is disclosed. The compressor and the turbine are each provided with vanes, each of which has a blade that forms a suction side and a pressure side, where at least one first of the blades is coated with a protective layer in order to reduce the erosion or wear. The layer is applied such that at least two areas are formed that adjoin each other at a boundary line. The first area has a protective layer that has a substantially constant first thickness and the second area is free of the protective layer or has the protective layer with a substantially constant second thickness, the second thickness differing from the first thickness. The boundary line has at least two points, of which the connecting line differs from the course of the boundary line between the two points.
