COMPARATIVE STUDIES OF DROP IMPINGEMENT EROSION AND CAVITATION EROSION.
Abstract
It has been theorized that the fundamental mechanism of cavitation erosion was essentially the same as that of impingement erosion. The tests conducted in the study were intended to provide additional cavitation and impingement data to support this theory. The tests were conducted on three materials supplied for round-robin cavitation test program. Complete cavitation tests and limited impingement tests on the three materials are described together with test data on two other metals. Further descriptive material on details for impingement testing is also included. Only a limited comparison of cavitation and impingement erosion was possible with the data available. This suggests that accelerated laboratory erosion tests may, in fact, over-accelerate the erosion to such an extent that it is not possible to tie the observed erosion to the prototype problem.
