Abstract

Magnesium (Mg) alloys offer exceptional strength-to-weight ratios and lightweight properties, making them attractive for aerospace, automotive, and biomedical applications. However, their susceptibility to corrosion poses significant challenges. In the present study Mg is alloyed with 5.5%Zn through stir casting. The prepared alloy was subjected to T6 aging. Corrosion behavior of the as cast and heat-treated alloy was evaluated through gravimetric and electrochemical tests. Weight loss data were collected after immersing the specimen in 0.85wt% NaCl solution at 37℃ to simulate in-vivo conditions. Wear tests were conducted using pin on disc apparatus in dry conditions varying sliding distance velocity and load, Results show that Mg-5.5Zn alloy exhibits improved corrosion resistance and wear resistance compared to cast alloy, with further enhancement after heat treatment.
