| Abstract: | The coatings were made by flame spray welding with self-fluxing alloy powder, NiCrSiB and CuNiSiB, in which WC particle was added. The coating's cavitation erosion was investigated with ultrasonic vibration cavitation instrument. The coating's cavitation erosion morphology was observed with SEM. Results show that the cavitation erosion resistance of composite coatings is better than that of base alloy. Cavitation erosion mechanism of the test coatings was also discussed. |
| Keywords: | cavitation erosion spray welding composite surface protection |
