Wear Behaviour of AM 050 Alloy Processed by Severe Plastic Deformation

摘要：

An Al-1050 alloy was processed by ECAP and HPT, respectively. Dry sliding wear tests were conducted on the as-received and SPD-processed samples under various sliding conditions. A comparison of wear rate indicated that SPD processing decreased the wear resistance. Two main wear mechanisms were observed. The initial wear stage was dominated by severe platelet wear mechanism and later wear was dominated by an oxidation wear mechanism. The results show the severe wear stage of SPDprocessed Al-1050 is much longer than that of the asreceived Al-1050, which is attributed to the loss of work hardening capacity after SPD processing.
