Abstract
The mechanical and tribological properties of spur gears are important because they can affect the efficiency and wear life of these gears. Thus, this study's primary goal is to use functionally graded material (FGM) to enhance the properties of Al2024 aluminium alloy spur gears. The mechanical and tribological properties of aluminium alloy Al2024 with graded Al2O3 reinforcement particles spur gears synthesized by the vertical centrifugal casting (VCC) process were investigated experimentally. Different weight percentages were used for the reinforcement particles, including 0, 2, 5, and 10 wt.% of Al2O3. Microstructural and mechanical properties were determined by SEM, EDS, and hardness tests. The Al2024/Al2O3 FGM spur gears were subjected also to dry sliding wear conditions. It was seen that hardness, strength, and wear resistance values increased by adding Al2O3 reinforcement particles to the Al2024 base material. In addition, the wear rate of FGM gears decreased by increasing the Al2O3 reinforcement particles in Al2024 alloy.
