Abstract We herein report the development of carbon-modified porous fillers that function as micro-reservoirs to store lubricating oil as a low-friction and anticorrosive agent in a composite coating. These novel oily particles were added to an epoxy resin (EP)-based coating to study the effect of a lubricating oil on the anti-corrosion and friction performances of the coating. Analysis by electrochemical impedance spectroscopy and sliding wear tests demonstrated that the presence of particles containing the lubricating oil significantly improved the barrier properties and the wear resistance of the EP coating. It was therefore apparent that the carbon surface modification of the Celatom filler improved the compatibility of both the filler towards the resin. Thus, the addition of fillers containing lubricating oil further improved the wear resistance and anti-corrosion properties of the coatings.
