Abstract
In the present investigation, the erosion wear of SS 410 stainless steel grade was evaluated under impact angles (300 - 900) and impact velocities (60-100 m/s) of erodent using a air jet erosion tester. Fly ash with particle sizes ranging from 75-100 microns was used as the erodent. Mass loss of each sample was measured to provide a reliable estimation of how much material was lost under the conditions. The highest erosion value occurs at 300 impact angle and 100 m/s impact velocity for SS 410. The characterization of the eroded samples was carried out through scanning electron microscopy (SEM) analysis of surface morphology. Pits, craters, and plastic deformation mechanisms were predominant at high impact angles (90°) compared to micro-cutting, ploughing, and lips at low impact angles (30°).
