The Influence of Temperature on Erosion Resistance of Carbide Coatings Deposited by APS Method

The carbide coatings are widely used for wear and erosion protection of different materials. In present paper the WC/Co coatings were deposited by a single-cathode Sulzer Metco F-4 plasma gun. The microstructure and thickness measurements were conducted. The erosion test was conducted using a Koechler Air Jet Errosion tester at the temperature of up to 500oC. The procedure was similar to ASTM G76 standard. Changes in erosion resistance of coating into different temperature were observed.
