Analysis of wear behaviour on the recycled aluminium mixed scrap modified with Zn using the Taguchi Approach

Abstract

Aluminum scraps are a common kind of recyclable material that are used in the manufacturing of a broad variety of lightweight and high-strength goods all over the globe. In order to further strengthen the toughness of these alloys, reinforcement is also used. This investigation makes use of a variety of aluminium scrap as the primary material, reinforcing it with zinc (Zn) at several concentrations, including 0 percent, 0.25 percent, 0.50 percent, 0.75 percent, 1 percent, and 1.25 percent, respectively. The design of experiments used to improve process parameters is put to use in order to investigate the wear of these composites (Taguchi technique). The investigation on wear was carried out using sliding velocities of 2 and 4 metres per second, a sliding distance that was held constant at 90 millimetres, and a weight that varied from to (10N, 20N). In this particular instance, the sliding distance served as an important part of the total three. According to the findings of the microstructure study, the samples included zinc particles, which showed decreased wear. According to the results of the corrosion test, zinc also serves a role that protects against the effects of corrosion. Aluminum alloy is the material that gets recycled the most all around the world.
