Abstract

An iron-cobalt alloy ceramic coating grows on the surface of Q235 carton steel in situ by the micro-arc oxidation technology; and the phase composition, elementary composition, surface morphology, surface roughness and thickness of the ceramic coating are analyzed by X-ray diffractometer, energy disperse spectroscopy, scanning electron microscopes, handheld roughness meter and coating thickness gauge. The results show that the morphology of ceramic coating is irregular porous structures at the surface and the elements of electrolyte and Q235 carbon steel matrix exist in the ceramic coating as amorphous phase. And then, the degradation of the rhodamine B (RhB) by the ceramic coating in a H2O2 Fenton system was investigated. The degradation rate of the rhodamine B solution can reach 99%; and meanwhile, the degradation rate is not reduced along the increased using times.
