Abstract

The performance of weathering decay of uncoated and Ni, Cu and Cd coated steel alloy 4130 in 3.5 wt. % NaCl solution was anticipated. The Ni-coated sample showed greater corrosion inhibition effect than both Cu-coated and Cd-coated depending on the obtained results of open circuit potential, polarization curves, cyclic voltammetry, and impedance spectroscopy. The surface of uncovered and covered electrodes are described by subjecting to scanning electron microscopy prior and afterward engagement in a salt solution. The best corrosion resistance and surface morphology achieved in Ni-coated steel alloy. The inhibition efficiencies of tested samples were 90.7, 89.1 and 56.9 for the Ni-coated, Cu-coated, and Cd-coated respectively.
