Slurry erosion of ductile materials under normal impact condition

Abstract

The phenomenon of erosion wear at normal impact of solid–liquid mixture has been studied in a slurry pot tester. The erosion wear tests have been carried out using seven different ductile type materials namely aluminium alloy (AA6063), copper, brass, mild steel, AISI 304L stainless steel, AISI 316L stainless steel, and turbine blade steel using three erodents namely, quartz, alumina and silicon carbide. Experiments are performed at 3 m/s velocity and 10 wt% concentration of 550 μm size particles for combination of different erodent and target materials at normal impact condition. It is observed that the wear at normal impact condition is a strong function of hardness ratio of erodent and target materials. Experiments are also carried out for different solid concentrations, particle sizes and velocities. Based on the experimental data, a correlation is proposed to predict the erosion wear at normal impact condition.
