Abstract

The Cu-P and Cu-P-SiC composite coatings on carbon steel substrates were deposited via electroless plating. The anti-corrosion properties of Cu-P and Cu-P-SiC coatings were studied in 3.5% NaCl solution. The anti-corrosion properties of Cu-P and Cu-P-SiC coatings were investigated in 3.5% NaCl solution by the weight loss, potentiodynamic polarisation and electrochemical impedance spectroscopy (EIS) techniques. It has been found that the shift in the corrosion potential (E corr) towards the noble direction, decrease in the corrosion current density (I corr), increase in the charge transfer resistance (R ct) and decrease in the double layer capacitance (C dl) values indicated an improvement in corrosion resistance with the incorporation of SiC particles in the Cu-P matrix. The effects of varying the SiC concentration on the corrosion resistance of carbon steel were investigated and it was found that the best anti-corrosion property of Cu-P-SiC is at 5 g L¯¹ SiC in the bath formulation.
