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 extended application, Zn-CeO 2 /ZnCeO 2-Al 2 SiO 5 thin film composite was fabricated on mild steel using direct electrolytic route. Process variation of Al 2 SiO 5 particulate ranges from 5 to 15 g per litre. The embedded coating was characterized 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 significant improvement in hardness trend. The tribological assessment indicated that there is less plastic deformation as a result of the counter body. In all, Zn-CeO 2 /Zn-CeO 2-Al 2 SiO 5 exhibits good stability, with agglomeration and great built up of crystal at the interface.
