並列タイトル等Construction of Database on Cavitation Erosion and Analyses of Carbon Steel Data
一般注記Cavitation erosion data has been accumulated in our laboratory since 1970 for about 30 years. The database was constructed in the electrical data of the Excel file. The data file is able to offer the quick search in terms of test material, test method and test condition among 859 data. The carbon steel data were analyzed, excluding stainless steels that exhibit the high work hardening. The average of erosion rate under the standardized condition (ASTM G32, stationary specimen method, standoff distance 1 mm) was determined for different carbon steels. Since the coefficient of variation was obtained in the range from O.l to O.3, the standard deviation can be easily estimated for these steel. The erosion resistance was defined as a reciprocal of erosion rate, and it was normalized with the erosion resistance of SUS 304 steel. The normalized erosion resistance is equal to 2.1 E-06×HV^<2.4> (HV; Vickers hardness), and the correlation coefficient is 0.92. It was concluded that the erosion resistance could be estimated precisely by the material hardness for carbon steels.
