A Tribological Study on the Effect of Reinforcing SiC and Al2O3 in Al7075: Applications for Spur Gears

In today’s world, efficiency and margin of safety are prime considerations for any applications. To address such parameters in aerospace or high-tech consumer products, there still limitations terms capabilities from a material perspective. Aluminium 7075 is predominantly used as combination these applications, but it has many drawbacks early wear/friction, low fatigue life cycle, high weight ratios, deformation stresses. overcome key issues, reinforcements have been to date. However, the results not so convincing with respect tribological aforementioned issues persist. current work, novel hybrid composite comprising substrate reinforcement silicon carbide aluminium oxide at varying combinations 3 9% steps 3% constant percentage 5% were added, respectively. The exhaustive work focuses on extracting mechanical, physical properties composite. Furthermore, microcharacterisation study was carried out using FE-SEM EDX. continuation this simulation, performed ANSYS Workbench identify suitable gear application real-time loading conditions. observed show tensile strength 366 MPa 6%SiC, hardness 93 VHN wear rate 0.00025 mm3/Nm 9%SiC combination.
