Abstract:
A crossed cylinder wear tester was used to measure the unlubricated wear rates of range of widely different sintered alloy steels: M42, T15, ASP30, D2, EN24. These alloy steels were made by a new process of powder metallurgy, where alloy steel powders are pressed and sintered into cutting tool parts. The results were applied to Archard's wear hypothesis and wear coefficient were determined. The test variables: abrasive grit size, load and speed of wear were analysed alongwith the material hardness and heat treatment conditions. It was found that Archard's wear hypothesis could be applied to the results and that this test gave an assessment of the wear resistance of these sintered alloy steels that was related to their performance in industrial service.
