Development of new testing method by centrifugal erosion tester at elevated temperature

To confirm that the new apparatus can obtain similar erosion data to the data obtained by conventional apparatuses, some preliminary experiments have been performed. As a result, it was confirmed that the new centrifugal erosion apparatus can obtain similar erosion rates and velocity exponents to the data obtained by conventional erosion apparatuses. The erosion rates of steels containing various amount of Cr obtained by the new centrifugal erosion apparatus showed similar tendency to the data obtained by Levy and Man [A.V. Levy, Y.-F. Man, Erosion-corrosion mechanisms and rates in Fe-Cr steels, Wear 131 (1989) 51] using a blast type erosion apparatus.
