Influence of Anticorrosive Coatings Integrated with Novel Core–Shell Pigment on the Corrosion Protection of Pipelines in CO 2 Environment

Interior corrosion of pipelines is a major and costly problem encountered in the oil and gas industry. Regarding this problem, coating systems based on waterborne and solvent-based binders integrated with novel core–shell pigment are formulated to maintain excellent mechanical and corrosion resistance. The novel pigment was synthesized using core–shell technique by precipitating layer of zinc and cobalt oxides on the surface of aluminum foil waste. Mechanical testing and electrochemical studies of coatings demonstrated that the integration of polyurethane and acrylic emulsion with the core–shell pigment can enhance the mechanical and corrosion resistivity. The results obtained in this work can be onset to the future use of treated wastes to enhance coating systems for corrosion protection purposes.
