Abstract

Abstract:

The surface of stainless steel was aluminized by hot-dip aluminizing process, the influences of dip time and dip temperature on the thicknesses of alloy layer and pure aluminum layer were analyzed to obtain the optimum process parameters, then micro-arc oxidation experiment was carried out. The bonding strength between the oxide film and epoxy resin was measured by the shear method, the microstructure of the micro-arc oxidation film was characterized by using SEM, XRD, and laser confocal microscopy to discuss and analyze the influence of micro-arc oxidation treatment of stainless steel on its adhesion to epoxy resin. The results show that the appropriate hot-dip temperature is 710 ℃, the appropriate hot-dip time is 11 min. The micro-arc oxidation film is mainly composed of α-Al₂O₃ and γ-Al₂O₃, and the oxidation film products are basically the same under different micro-arc oxidation time. Both the surface roughness of ceramic film and the micro-arc oxidation film-epoxy resin bonding strength increase with the increase of oxidation time. When the time increases to 30 minutes, the maximum surface roughness is 1.265 μm, the binding strength increases to the maximum value 33.20 MPa and being 2.8 times that of untreated samples.
