Wear resistant, high-impact, iron alloy member and method of making the same

摘要

An impeller shoe (110) having a front side (112) with a series of half column members (114) and raised upper and lower rims (116, 118) that form the impact surface of the impeller shoe. Half columns (114) and raised rims (116, 118) are formed with carbide material (120) formed therein in order to improve wear resistance at these critical surfaces.
