Effect of Epoxy-Egg Shell Nanoparticle Composite Coating on the Microstructure and Mechanical Properties of Mild Steel

Oisakede M.O, Sadjere E.G


Nanoparticles due to their large surface areas have been shown to be excellent materials as they are good absorbents of coating pigments. In this research, an attempt has been made to develop a novel epoxy-egg shell ash nanoparticle (ESAnp) composite coating on mild steel. Sol-gel method was used to produce the nanoparticles. A 1, 2, 3, 4 and 4wt% ESAnp were added to epoxy.  The coating was done using spraying method.  The microstructure, coat thickness, hardness values and adhesion strength were determined. Improvement of hardness values and adhesion strength of the mild steel were obtained 4wt% ESAnp at 43.48 % and 190.4%.  The results obtained from this work showed that epoxy-4wt% ESAnp has best properties for adhesion strength and hardness values.

Keywords: Mild steel, Epoxy, Nanoparticles, Egg shell ash, Hardness values, Adhesion strength.
