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