A Magnetic Properties and Corrosion Resistance of Fe-Si Alloy Coating Prepared on Mild Steel
Keywords:Nano-Si, mild steel, magnetic properties, Corrosion resistance
AbstractThe present work deals with preparation of Fe3Si coatings on mild steel and evaluation of its magnetic property and corrosion behavior. Magnetic property of coatings was measured using a vibrating sample magnetometer, the result shows that the saturation magnetization reached to the maximum value (214.1 emug-1) and the coercivity fell to the lowest (23.11 Oe) in 1000oC. Corrosion behaviour of the coatings was studied using polarization in 3.5%NaCl solution. It was found that the corrosion current density (icorr) decreased with increasing of heat treatment temperature up to 1000oC, indicating an improvement in corrosion resistance.
