Özet:

In this study, ZW21 alloy one of magnesium (Mg) alloys containing Zinc (Zn) and Yttrium (Y) was produced by gravity casting method then its microstructure, hardness, corrosion and wear properties were investigated. The microstructure images of the produced alloys were made by classical metallographic methods such as sanding, polishing and etching. Microstructure images were taken with optical and SEM devices and EDX analyzes were performed. The hardness of the metallographically prepared samples was determined by Brinell hardness tester. To achieve in vitro experiments, potentiodynamic polarization and immersion tests were performed in Hank's solution at (36.5 ± 0.5ºC). In addition, in the corrosive wear tests, a reciprocating wear test device was used to implement the necessary experiments under constant load, at constant speed and distance also with Hank's contact conditions. According to XRD results, the presence of I and W phases was determined. The hardness of the materials was found to be 52.55 HV. It was observed that the corrosion rate slowed down over time and an oxide film layer was formed on the sample surfaces. A significant mass loss was detected in corrosive wear depending on the distance.
