Abstract
Slurry abrasion wear is a potential problem in engineering components subjected to particulate flow. Hardfacing by welding is one of the economic methods to improve wear life of engineering components. The present work deals with the slurry abrasion behavior of the mild steel and weld deposited alloy steel. The experiments were performed using silica sand slurry with different slurry concentration, load, total revolution & particle size for both mild steel & weld deposited martensitic steel. The results of the investigation suggest that slurry concentration had relatively stronger effect on wear than the normal load for both steels and the weld deposited alloy steel exhibits better slurry abrasion wear resistance than mild steel. The morphological studies of the worn surfaces revealed characteristic differences in the wear pattern under different test conditions and the operating mechanisms of material removal involved ploughing and cutting.
