| Abstract | ||||
| The cavitation erosion of carburized and untreated low alloy steel (AISI 5117) has been investigated during the incubation period. Scanning electron microscope images of eroded surface were obtained, forming a data base for further analysis. It has been shown that carburizing can effectively improve the cavitation erosion resistance of AISI 5117 low alloy steel and prolong the incubation period. The fractal dimension and Fourier intercept values can be used to characterize the cavitation damage. The fractal dimension and Fourier intercept value for the untreated surfaces were higher than that of the carburized surfaces. | ||||
