Estimation of Incubation Period at Cavitation Wear of Steel through Measuring Roughness
Abstract
A new procedure of assessing incubation period in cavitation wear of low-alloyed and low-carbon steels is reported. To simulate cavitation wear an ultrasonic vibratory apparatus is used. The experiments are carried out in fresh water. The weight loss and arithmetical mean deviation of the assessed profile are measured at appropriate intervals during the test. The dependence of arithmetical mean deviation of the assessed profile on cavitation attack duration turned out to be a broken line divided into three sections. The points of inflections indicate the change in mechanisms of asperities formation. The boundary point between the first and the second section of the dependence can be used to indicate the end of an incubation period.
