In this study, wear behaviour of AlB 2 /Al composite materials produced through in-situ method have been experimentally investigated. Four different composite materials that include 5wt.%, 10wt.%, 20wt.% and 30wt.% AlB 2 reinforcement phase were tested using pin-on-disk arrangement. The effects of the rate of reinforcement on wear and friction behaviours have been investigated. Wear tests are carried out at 1.83, 3.40 and 4.71 m/s sliding speeds under 10, 20 and 40 N applied loads. The test results show that wear rate increases with the increase in applied load and sliding distance. Increasing the rate of reinforcement phase in the matrix has proportionally increased the wear resistance by 3% to 30%. Hence the greatest wear resistance has been observed with the composite materials having 30wt. % AlB 2 reinforcement. Analysis of the worn surfaces of composite samples shows that abrasive and adhesive wear mechanisms are more effective.

In the present study, an AlB2-reinforced functionally graded aluminium matrix composite has been produced by centrifugal casting. Boron 1.2–1.85% by weight has been dissolved in aluminium at 1400℃ by adding boron oxide resulting in AlB2 flakes 2.71–4.20% by weight before being cast centrifugally at 800℃. Results showed that there were two distinct regions without a smooth grading: one is rich of AlB2 and the other is poor of AlB2. The highest AlB2 content has been found to be around 11% in outer zones, whereas the lowest AlB2 content has been observed to be below 0.02% in inner zones. Results also showed that, depending on the increase in the reinforcement phase in outer zones, up to 64% increase in the strength and hardness of the composite has been achieved.
