The influence of speed on the wear of sintered iron-based materials

A pin-on-disc-type wear test rig was used to study the influence of speed on the wear of sintered iron, sintered Fe-5Cu and sintered Fe-5Cu-5C materials over a range of speeds of 0.5 -16 m s-1 at a constant load of 40 N. With increasing speed the wear rate decreases to a minimum and then increases. Over the entire range of speeds two types of wear are observed: these are mild wear below a speed of 8 m s-1 and severe wear above a speed of 8 m s-1. The results are discussed in terms of friction records, wear particle size and composition, wear track study and topographic and metallographic studies of worn specimens. © 1981.
