摘要：
The electrodeposition of Ni-Fe-Cr alloys was investigated in a trivalent chromium electrolyte on the surface of mild steel over a range of current density. Scanning Electron Microscopy (SEM), Tafel plot and Electrochemical Impedance Spectroscopy (EIS) measurements were used to compare plated alloy coatings and heat-treated electrodeposited alloy coatings. The heat-treated alloy coatings showed a relatively large impedance values and corrosion inhibiting efficiency. Moreover, the polarisation resistance R-p, was obtained by EIS modeling using equivalent circuits.
