In this study, reciprocating and continuous abrasive wear tests have been performed on solution-treated 2014 Al alloys under similar conditions of load, speed, nominal area of contact and sliding distance in order to compare the two-body abrasive wear behavior for two sliding modes. It has been established that the pattern of wear is similar for the 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 values of the wear loss and the abrasive wear coefficient for continuous wear were higher than those for the reciprocating wear. The differences in wear behavior of the test material for the continuous and reciprocating abrasive wear can be explained in terms of the sliding-distance differences between the continuous and reciprocating motions at the same test conditions and the differing amount of abrasion in the two processes by the loose wear debris.
