Abstract

Steel is renowned for its economical manufacturing, exceptional mechanical strength, and hence finds widespread use in drilling equipment, pipelines, shipbuilding, and offshore structures. Corrosion of steel is an expensive issue in many applications, particularly in oilfield and marine settings renowned for high temperatures, pressure, and corrosives. In this paper, multi-walled carbon nanotubes (MWCNTs) coating is investigated to increase corrosion resistance for steel. MWCNTs were introduced to a metal matrix composite, such as Ni–P, using the electroless process. Various characterization techniques such as Field Emission Scanning Electron Microscope (FESEM), X-ray diffraction (XRD), Atomic Force Microscope (AFM), and Vickers Hardness test were performed to determine the physio-chemical and mechanical properties of the coated Steel bar. Additionally, Electrochemical impedance spectroscopy (EIS) and polarization method were used to determine its corrosion resistance behaviour. The corrosion potentials for the bare substrate, Ni–P coated, and CNT doped (Ni–P–CNT) coated are −476, −432, and −350 mV, respectively. The I.E (%) of the CNT doped coating is 26.5% more than the Bare substrate, and the Ni–P doped coated specimen is 14.6% more than the bare substrate. These results showed that the CNT doped coating exhibited higher corrosion resistance than Ni–P doped and Fe 500 substrate.
