| Abstract | ||||
| The present paper deals with the investigation of wear and friction characteristics of 10 vol.% Sic particulate reinforced 2124A1 composite in addition to its unreinforced 2124Al alloy. A pin-onring apparatus has been employed. The effects of the normal load, sliding speed, and sliding time on mass loss and coefficient of friction were examined. The specific wear energy and the activation energy were also estimated in order to gain more understanding of the mechanisms that control wear in these materials. The present results show, for both materials, that mass loss linearly increases with increasing normal load and sliding time. It is also observed that increasing sliding speed leads to a complicated wear manner. The unreinforced alloy has the greater mass loss when compared with the reinforced composite, but when increasing sliding speed, the unreinforced alloy exhibits minimum values of mass loss. In all cases, the coefficient of friction is greater, for the present composite, than that for the unreinforced alloy. Furthermore, wear mechanisms were investigated and discussed in the light of microscopic observations. | ||||
