Fig. 2 is a Scanning Electron Microscope (SEM) photograph of the surface of the coating from which it can be seen that the epoxy resin bonds the hydrophobic silica and mica particles together well and forms a denser coating on the surface of the substrate. The surface of the coating has a micro-nano coarse structure, partial nano silicon dioxide in the glue solution is agglomerated by airflow in the spraying process to form approximately spherical micro aggregates, and meanwhile, the surface of the substrate is observed to be completely covered by the coating, so that the wear resistance and the corrosion resistance of the coating are improved.
