dc.description.abstractSurface enhancement of engineering materials is necessary for preventing service failure and corrosion attack in the industries. Deposition was performed to obtain a better surface adherent coating using electroplating technique. Zn-Al film was developed with zinc and aluminum powder particles dissolved in nitric acid and sodium hydroxide respectively, to form solutions containing Zn2+ and Al3+ions. Anomalous co-deposition on mild steel resulted into surface modification attributed to the complex alloys that was developed. The effect of deposition potential was systematically studied using Focused-ion beam scanning electron microscope (FIB-SEM), Atomic force microscope (AFM), X-ray diffraction (XRD) and Fourier transform infra-red (FTIR). Thick, adherent, smooth and uniform Zn-Al coating was deposited with relatively high deposition rate of 1.0 V. Experimental results indicated that the introduction of Al into the coating does significantly alter the chemical and mechanical properties of the mild steel. The microhardness value was increased by 92%; wear rate was decreased by 90% and a significant increase in the corrosion resistance was achieved based on the formation of stable deposited particles of Zn-Al.
