Abstract
This research is concerned to realize the transition of different wear modes for unlubricated sliding wear of AA7068 alloy-4% ZrO2p composite system. For this purpose, the wear mechanism maps are constructed in conformity with the characteristics of wear rate and temperature shown on the load versus speed diagram and wear surfaces generated at salient stages while conducting the test. To identify the transition of one wear mechanism to another, critical speed and load values are computed. The wear coefficient ranges from 10–4 to 10–5, which has been realized at the mild-to-severe wear line. Ultra-mild wear (particularly in composite), mild wear (oxidational), delamination, and severe wear have been the prevalent wear regimes discovered throughout this work.
