Abstract

The rotor of an axial-flow compressor with means for sealing the rotor blade tips relative to a casing wall provided with a coating is to be capable of abrasion but at the same time also low in wear. The present invention resolves these contradicting requirements for the coating on the casing in that individual blades, arranged between normally contoured, unshrouded rotor blades, are widened at their tips and reinforced with a radially outer layer, the material of which is matched to that of the coating. This will enable the coating to be subjected to less wear and to offer more resistance to erosion than heretobefore.
