A COMPARISON OF THE RECIPROCATING AND CONTINUOUS 2-BODY ABRASIVE WEARBEHAVIOR OF SOLUTION-TREATED AND AGE-HARDENED 2014-AL-ALLOY

In this study, reciprocating and continuous abrasive wear tests have b een performed on solution-treated 2014 Al alloys under similar conditi ons of load, speed, nominal area of contact and sliding distance in or der to compare the two-body abrasive wear behavior for two sliding mod es. It has been established that the pattern of wear is similar for th e continuous and reciprocating wear. On the other hand, the values of the average roughness of the worn surfaces for the reciprocating wear were higher than those for the continuous wear. This is because the va lues of the wear loss and the abrasive wear coefficient for continuous wear were higher than those for the reciprocating wear. The differenc es in wear behavior of the test material for the continuous and recipr ocating abrasive wear can be explained in terms of the sliding-distanc e differences between the continuous and reciprocating motions at the same test conditions and the differing amount of abrasion in the two p rocesses by the loose wear debris.
