【 摘 要 】

The tribological characteristics of Aluminium metal matrix with different nano BN powder compositions were investigated using pin on disc tribometer. The pure aluminium, Al +1 wt% BN, Al + 3wt% BN, and Al + 5wt% BN compositions are prepared as 36 specimens using Powder metallurgy technique. In each composition 9 specimens undergone testing with three different load conditions and three different sliding velocities applied at constant sliding distance of 1000m. The result shows that when there is increasing the weight percentage of BN nano particles in aluminium metal matrix there is reduction of coefficient of friction by increasing the load and sliding velocities. Similarly the specific wear rate also gets reduced by increasing the load and sliding velocity.
