摘要：
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(-5) which 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. (C) 2012 Elsevier Ltd. All rights reserved.
