Abstract

Experimental pin-on-disc wear tests were carried out previously on three types of commercial A6061 aluminum-based matrix composites (MMCs) reinforced with 10, 15 and 20% alumina particles, respectively, against steel disc, with both the moving-pin technique developed at Nanyang Technological University and the conventional pin-on-disc technique. An integrated wear model was established, with the transient wear volume described by an exponential equation while the steady-state wear by a revised Archard equation. A wear coefficient equation was formulated by using the transient wear data to model the standard wear coefficients of both the transient wear and the steady-state wear successfully. In this study, a new equation was developed from the previous model to predict the net steady-state wear coefficient. With a F A value of 0.999 or 0.9999, the average deviation from the measured values was about 26%. F A was an exponential function used in the transient wear equation. On the other hand, Peterson's equation was also found suitable for modeling the steady-state wear of the three types of aluminium-based matrix composites. However it lacked some of the features the newly proposed equation could provide.
