Study of Al2O3/SiC particle loading on theudmicrostructural strengthening characteristics ofudZneAl2O3eSiC matrix composite coating

摘要

In this paper, the microstructure, and mechanical performance of ZneAl2O3eSiC film codepositedudon mild steel substrate were produced by electrodeposition method. Theudstructural characteristic of the composite coating was analyzed by scanning electron microscopeud(SEM) equipped with energy dispersive spectrometer (EDS), X-ray diffractionud(XRD) and atomic force microscope (AFM). Mechanical examination was done usinguddurascan hardness tester. The result showed that the influence of individual particleudloading greatly alter the structural properties and hardness behavior. The increase inudhardness is attributed to the perfect homogeneity and characteristics of the particulateudwhich led to the formation of uniform distribution, coherent and interfacial precipitationudwithin the zinc lattice.
