Abstract

Erosion, cavitation, and impingement are mechanically assisted forms of material degradation that often contribute to corrosive wear. This article identifies and describes several tests that are useful for ranking the service potential of candidate materials under such conditions. The tests, designed by ASTM as G32, G73, G75, and G76, define specimen preparation, test conditions, procedures, and data interpretation. The article examines the relative influence of various test parameters on the incubation and intensity of cavitation, including temperature, pressure, flow velocity, and vibration dynamics. It concludes with a discussion on data correlations and the relationship between laboratory results and service expectations.
