Hot-Corrosion behaviour of mild steel at different Ni-Cr coatings thickness are studied, and also resistance offered by different coating thickness is also investigated. Hardness of mild steel was found to be increased from 202.25 to 341.75 VHN after the application of coatings. Parabolic rate constant (Kp) for high temperature oxidation of bare, 200-250µm, and 250-300µm thick Ni-Cr coated mild steel were calculated to be 1232.47, 3.98677, and 5.05509 (×10-10g2cm-4s-1) respectively.
