Wear of Cast Irons
This article presents typical wear applications for a variety of cast iron grades in a table. In general, wear is classified according to three major types: adhesive (frictional) wear (sliding and rolling) caused by contact of one metallic surface with another; abrasive wear caused by contact with metallic (shots, swarf) or nonmetallic abrasive materials; and erosive wear. The article discusses general wear characteristics of gray iron, compacted gray iron, and ductile iron. It provides information on the brake lining chemistry effects, graphite morphology effects, normal cast iron wear, local cast iron wear, and external abrasive effects on brake drums and disk brake rotors made of gray cast iron. The article concludes with a discussion on the application of cast iron for grinding balls.
