Magnesium RZ5/10 wt.% TiB2 in-situ composite was synthesized using self-propagating high temperature synthesis route and its tribological behaviour was investigated for the application in the aerospace industries. The wear behaviour of both RZ5 alloy and RZ5/10 wt.% TiB2 composites were studied using pin-on-disc wear testing apparatus. The wear characteristic was analysed under different loading conditions of 10, 20 and 30 N, and sliding distance of 1000, 2000 and 3000 m. Significant improvement in the wear resistance was observed by the addition of TiB2 reinforcement in the magnesium RZ5 alloy matrix. It was concluded that increasing the applied load wear loss increases with a corresponding decrease in the coefficient of friction. Moreover, with an increase in the sliding distance, both wear loss and coefficient of friction increases. The mechanism of wear and debris formation for both RZ5 alloy and composites at different loading conditions were examined using FESEM.
