This paper examines the electro-mechanical responses of electrodeposited Zn-ZnO-MgO composite coating from sulphates bath with emphasis on its hardness and wear characteristics. The ZnO/MgO modified Zn series co-deposition was obtained from ordinary sulphate-based bath consisting of 16g/l MgO and 30g/l ZnO particulate. The particles were dispersed by mechanical agitation at 200rpm. The presence of the MgO and ZnO were confirmed by high magnification optical microscope (OPM). The hardness and wear propagation were examined by diamond based microhardness tester and MTR 300 Abrasive wear tester. The results indicate that the inclusion of the nano-sized particulate leads to excellent tribological behavior and increase hardness behavior. The thermal stability characteristic was also sustained over time.
