| Abstract: | This paper researches the effect of the factors, such as different hitting speeds and different abradant sizes, on erosive wear rate of plasma spraying Al 2O 3 ceramic coating, in the condition of solid grain erosion, and has comparative tests with 20# steel. In different condition, the erosive wear character and mechanism of the coating have been analyzed. It is posed that plasma spraying Al 2O 3 ceramic coating has brittleness character and fits to the erosion condition of minute abradant and low speed. |
