This research is concerned to realize the transition of different wear modes for unlubricated sliding wear of AA7068 alloy-4% ZrO_2p 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.

本研究旨在实现AA7068合金-4% ZrO _2p复合体系无润滑滑动磨损不同磨损模式的过渡。为此，根据负载与速度图上显示的磨损率和温度特性以及在进行测试时在显着阶段产生的磨损表面，构建磨损机制图。为了识别一种磨损机制到另一种的转变，计算临界速度和负载值。磨损系数范围从 10 ^–4到 10 ^–5，这在轻度到重度磨损线已经实现。超轻度磨损（特别是复合材料）、轻度磨损（氧化）、分层和严重磨损是在整个工作中发现的普遍磨损状态。
