The wear behaviour of wear resistant alloy steels has been studied using a crossed-cylinder wear test. The wear results have been related to current theories of friction and wear established in the published literature. Wear tests have been carried out on a wide range of alloy steels sintered in vacuum to full density; in particular the following have been studied in depth: M2, M42, T15, ASP30, D2 and EN24. These alloy steels were made by the process of powder metallurgy where alloy steel powders of the co=ect =mposi tion are pressed and sintered into wear resistant engineering ccmponents . A wear test method involving a crossed cylinder abrasion test has been developed to measure the wear rates of materials with hardnesses ranging from 100-1000 VHN. The test variables studied were: time (or distance travelled), load,abrasive grit size, sliding speed and hardness of test specimens ...
