| Abstract | ||
| This work focuses on the effect of electro-deposition of nickel on corrosion behavior of mild steel substrate with ultra fine Al2O3 and SiC using the electroplating technology. The experimental results exhibited the substrate microstructure was sensitive to both current density and temperature. Grain growth were increased with increasing each of current density and temperature and thereafter decreased. Optimal values were 0.2A/cm2 and 45C°, respectively. Concentration of each Al2O3 and SiC were essential to electro-deposition, it was found 4gm/l after traditional weight loss technique was performed, it was found that corrosion rate of Ni and Ni- Al2O3 was deceased with exposure time in 3.5% NaCl solution whereas Ni-SiC exhibited higher corrosion rate. the addition Al2O3 was inhibited corrosion in acid solution. | ||
