铝基复合材料的磨损机理图有助于预测和理解材料中不同的磨损机制。它还确定了一种磨损机制向另一种磨损机制转变的临界载荷和滑动速度。在本研究中，磨损系数在10−4-10−5范围内，介于轻度磨损和严重磨损之间。还观察到了四种磨损形式，即超轻微磨损、轻度磨损或氧化磨损、剥层磨损和严重磨损。并从普遍的磨损机理出发，对这些因素进行了讨论。
Wear mechanism map for aluminium matrix composite helps in predicting and understanding different wear mechanisms in a material. It also identifies the critical load and sliding speed for transition of one wear mechanism to other. In the present investigation, the wear coefficient is in the range of 10−4–10−5which is at the boundary region between mild to severe wear. It is also observed from that there are four wear regimes; they are ultra mild wear, mild wear or oxidative wear, delamination wear and severe wear. All these facts are discussed on the basis of prevailing wear mechanism.
