%X Deterioration of metals and alloys due to corrosion has been observed to be a serious challenge in  coastal or marine environments. Exposure of mild steel to marine environments often results into  dilapidation of physical structure over time. This study addresses the quick response of mild steel  failure using NiZnP modified Al2O3 functional composite by electrolytic process. The deposition was  done with stable pH of 4.5, heated bath temperature of 95°C, stirring rate of 200 rpm and deposition  time of 20 min. The materials chemistry of the developed alloy was examined using open circuit  potential and linear polarization technique. The structural mechanism and crystal phase formation  was characterized using scanning electron microscope (SEM) equipped with energy dispersive  spectrometer (EDS) and X-ray diffraction analyzer. The corrosion results under 3.65% saline  environment reveals improved corrosion rate of NiZnP modified Al2O3. The surface site of the crystal  formation evolves perfectly with hexagonal structure seen along the grain boundaries.
