Abstract

abstract

Airfoils of gas turbines and jet engines frequently deteriorate by erosion or corrosion: Protection can be offered by special coatings that are resistant to either erosion or corrosion. However, the conventional corrosion resistant compressor coatings have very poor erosion resistance. Therefore there is a tendency to apply compressor coatings that offer protection against both erosion and corrosion.

The erosion resistance of (improved) conventional aluminium-based compressor coatings and of new TiN, Ti2B and WC coatings was determined at 150° C as a function of the angle of attack. The Ti2B coating had especially promising erosion resistance.
