A Mechanistic Model for Prediction of Ductile Erosion

Abstract

Mechanisms operative in dust erosion of ductile materials were determined with the aid of scanning electron microscope studies. Dimensional analysis was employed in the development of a mathematical model for predicting erosion of ductile materials. The basis of the model was the predominant identified erosion mechanism, target melting. The model was verified in an erosion testing program. Target materials in the testing program were three stainless steels, two aluminum alloys, a beryllium-copper alloy, and a titanium alloy. Erosive agents were three dusts comprised of hard, angular particles and one dust with spherical particles. Maximum particle velocities were 130 or 250 meters per second.
