AbstractNi-B/Ni-P-CeO2 duplex coatings containing inner Ni-B layer were synthesized on mild steel substrate through the electrodeposition process. The structural, surface and electrochemical properties of the duplex coatings in their as synthesized condition were compared with Ni-P, Ni-B and binary Ni-B/Ni-P duplex coatings to demonstrate the improved performance of Ni-B/Ni-P-CeO2 duplex coatings. The structural analysis (XRD) indicates that the developed coatings exhibit amorphous behavior. The SEM and AFM studies indicate that Ni-B/Ni-P-CeO2 duplex coatings have less surface defects and more defined nodular structure compared to Ni-P, Ni-B and NiB/Ni-P duplex coatings. However, these coatings show an increase in surface roughness which may be attributed to the incorporation of CeO2 ceramic particles used as reinforcement. The Ni-B/Ni-P-CeO2 duplex coatings present superior anticorrosion properties compared to Ni-B and duplex Ni-B/Ni-P coatings. Owing to tempting properties, Ni-B/Ni-P-CeO2 duplex coatings may be considered as potential candidate for oil and gas industry.
