Abstract

The work investigated adhesion strength and wear performances of value-added epoxy composite coating of mild steel using a sustainable material (activated orange juice) for functionalization of rice husk ash nanoparticles (RHAnp). The transmission and scanning electron microscope, X-ray diffraction, atomic force microscope, wear test, and adhesion strength were used in the characterization of the developed composite coating. A 70.23 and 78.07% increase in coating thickness and reduction of the surface roughness of the substrate were obtained with the addition of 2 wt% functionalized RHAnp. A total of 68.12% and 72.06% increments in hardness values and adhesion strength were obtained after coating with 2 wt% modified RHAnp. High adhesion strength recorded at epoxy-2 wt% modified RHAnp was attributed to grain sub-structure formed after functionalization and resulted in high dislocation density. A 67.19% improvement in wear resistance at epoxy-2 wt% modified RHAnp over that of the substrate was obtained. Activated orange juice can be used to functionalize RHAnp for enhanced adhesion strength and wear performances of epoxy-coated mild steel.
