Abstract


The 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 emu•g-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.
