Abstract:
In this study the influence of alloying elements on cavitation resistance of quenched and tempered carbon steel was investigated. The first test included quenched and tempered carbon steel without alloying elements. The second test included previous mention steel with alloying elements such as chromium and molybdenum. Cavitation erosion tests were performed using an ultrasonic vibratory cavitation test method. Scanning electron microscopy technique was performed to analyze the morphology of the damaged surfaces and to interpret the results of the cavitation tests. The results showed that the presence of alloying elements influence on the reduction of cavitation rate and reduce the degree of cavitation damage after certain time intervals the effect of cavitation.
