A Room Temperature Pre-Treatment Process: Ce3+ Doted ZrO2 Nanofilm Coated on the Cold-Rolled Plate Surface

The purpose of this paper is to study the anti-corrosion properties of a novel pre-treatment CeO2/ZrO2 nanometric film coating on the surface of cold-rolled plate at room temperature. A novel coating agents involved elements Zr,Ce and additional surfactants were prepared and used in the field of cold-rolled plate pretreatment. The surface of the coating sample was investigated by using X-ray Photon Spectrum (XPS), X-ray Diffraction (XRD) and Scanning Electronic Microscope (SEM)，respectively. The Ce3+ doted ZrO2 nanofilm could improve the anti-corrosion performance of coated plate. This dipping coating process satisfied the energy-saving and green chemistry requirement of modern cold-rolled plate pre-treatment technology.
