Abstract
γ-Al2O3 coatings were prepared on aluminum-free SUS304 stainless steel by an electrophoretic deposition method. Both TG-DTA and Scanning Electron microscopy are used to study the adhesion property and morphological features of coatings. The results indicate that the thickness of coatings on SUS304 top reaches 3-5 μm without any exfoliation, which is prepared at optimize conditions. Catalytic properties of coated samples for NOx were highly enhanced as compared with the samples prepared by the dip coating method.
