REDUCTION OF CAVITATION DAMAGE BY SURFACE TREATMENT.
Abstract
A rationale and selected experimental evidence indicate that surface outgassing may contribute significantly to erosive damage in metals exposed to a cavitation environment. The possibility of inhibiting outgassing and consequent cavitation erosion by suitable surface treatments is experimentally examined. Tests of various surface treatments on an ASME type vibratory test apparatus failed to disclose significant benefits except in the case of a work hardening steel treated by shot peening. It is concluded that Poulter's earlier findings on protective films do not hold for metals exposed in a high intensity cavitation test facility. (Author)
