Preparation and performance analysis of Pottery and porcelain film on Cold rolled steel plate

The ceramic film is prepared by fluorozirconate solution on the surface of cold-rolled steel plate, and the phosphating treatment before coating is not conducive to environmental protection operation. In this paper, scanning electron microscope and energy spectrometer are mainly used to analyze the morphology and elemental composition of the ceramic film, and the corrosion resistance performance of the ceramic film is analyzed by electrochemical testing technology and neutral salt spray test. At the same time, the ceramic film is tested The coating adhesion of the ceramic film was analyzed, and the film-forming mechanism of the ceramic film was analyzed. From the experimental research, it can be concluded that the ceramic film is composed of oxides of zirconium and iron, the film layer is extremely thin, and different film forming times will show different film colors; Effective enhancement, but the length of film forming time has relatively little effect on the corrosion resistance of the film; the adhesion between the ceramic film and the epoxy resin paint layer or polyurethane paint layer is 0, which can meet the needs of painting.
