This paper compares three thermally sprayed coatings with different carbide types in a NiCr matrix (25% by volume) with regard to their erosion, corrosion, and wear resistance. The three types of carbide are WC, chromium carbide, and TiC. The coatings were sprayed with the Sultzer-Metco Diamond-Jet 2600 equipment. All coatings were produced with the same spray parameters. If the sand particles hit the surface at high angles of impact, the WC coating is better than the other two coatings in terms of erosion/corrosion resistance. Micro-abrasive wear tests also showed the WC coating was superior (slightly better than the TiC coating). The corrosion properties of the coatings were almost the same. Paper includes a German-language abstract.
