Abstract This study was aimed at improving the stability and protection capacity of carboxymethyl cellulose (CMC) by combining copper, iron and nickel nanoparticles (Cu NP, Fe Np and Ni NP) produced in situ through the deposition of various metal oxide nanoparticles into a CMC matrix. The fabricated CMC as well as CMC/Fe NP, CMC/Cu NP and CMC/Ni NP nanocomposites were characterized by field emissionscanning electron microscope (FE-SEM), Fourier transform-infrared spectroscopy (FT-IR), energy-dispersive X-ray spectroscopy, transmission electron microscope, selected area diffraction pattern and X-ray diffraction techniques. The investigations of electrochemical methods, such as electrochemical impedance spectroscopy and potentiodynamic
polarization (PDP), reinforced by surface morphology studies (FE-SEM, and FT-IR) were organized to explore the prepared materials’ protection abilities on a carbon steel electrode in 2 N of HCl. The highest protection power for the CMC as well as CMC/Fe NP, CMC/Cu NP and CMC/Ni NP composites at 400 mg L-1 were 76.6, 94.9, 96.2 and 98.4%, respectively. FE-SEM/EDX and FT-IR examinations confirmed that the prepared nanocomposites could successfully block an aggressive attack with Cl- via chemical adsorption on the steel, in accordance with the adsorption model of Langmuir. PDP data indicated that the nanocomposites could deliver superior corrosion protection and exhibited mixed-type inhibitors.

Introduction Steel alloys are extensively utilized in different industry applications due to its low cost and excellent mechanical properties, durability, hardness, ductility and corrosion resistance (Lopez et al. 2004). The major problem associated with steel alloys is that they are prone to corrosion when they come into contact with hostile environments, such as acids (hydrochloric acid [HCl] and sulphuric acid), which are used in many oilfield operations, such as acid descaling, acid cleaning, acid pickling and the acidizing of an oil well (Azzam et al. 2015; Heydari and Javidi 2012; OrtegaToledo et al. 2011). One of the most economical approaches for monitoring the steel alloy corrosion that o
