Compressor components of gas turbines are often protected against corrosion by metallic coatings. These thin coatings are prone to erosion, however. Two coatings applied to compressor vanes of a jet engine were erosion tested under simulated service conditions. Some tests on coated coupons were also performed. The tests on the vanes gave the most reliable results. The erosion resistance of the two coatings was more or less equal. In order to facilitate the recognition of erosion damage attention was paid to its appearance.
