Mechanical and tribological behavior analysis of metal powder reinforced filled 7075 aluminum alloy composites for Gear material application

The research work shows the results obtained from the geometric and mechanical properties of Al7075 alloy compounds reinforced with copper metal powder (0-2% by weight) for gear materials produced by high vacuum casting. The wear test is carried out in a multi-sample tester in a lubricated state. The composite model produced will be used as a newly developed material for the manufacture of gears in the automotive industry. The introduction of the charge of copper particles can cause significant changes in the behavior of these materials. Bending force (329-499 MPa), tensile force (232-396 MPa) and impact force (20-70 kJ / m2) of grain-reinforced alloy composites improve mechanical properties by increasing copper metallic powder. 0% to 2%.0% of each volume. Experimental results showed that the composite material consisting of copper metal powder particles showed the lowest wear index compared to the base alloy, and the wear resistance of the composite material improved it.
