ABSTRACT: Process engineering has been seen as one of
the vital tools for improving surface coating phenomena for advance
application. In an attempt to improve the mechanical, physical and chemical
performance of the steel structure for ex-tended application,
Zn-CeO2/ZnCeO2-Al2SiO5 thin film composite was fabri-cated on mild steel using
direct electrolytic route. Process variation of Al2SiO5 particulate ranges from
5 to 15 g per litre. The embedded coating was charac-terized using Scanning
electron microscope (SEM). The chemical effect of the developed alloy was
characterized through linear potentiodynamic polarization experiment and the
performances of samples were examined in simulated 3.5% sodium chloride. The
microhardness verification study proves that there is sig-nificant improvement
in hardness trend. The tribological assessment indicated that there is less
plastic deformation as a result of the counter body. In all,
Zn-CeO2/Zn-CeO2-Al2SiO5 exhibits good stability, with agglomeration and great
built up of crystal at the interface.
