Abstract The effect of substrate preheating time on the interface bonding of fusion bonded epoxy powder coating/Q345 substrate was investigated by means of tensile test and wet adhesion test. Results showed that the preheating time presents significant effect on the interface bonding of coating/Q345 substrate, and among others, the best bonding performance could be acquired for the substrate being preheated for 6 h at 210 ℃. The surface morphology, roughness and chemical composition of the substrate were characterized by CLSM, AFM, XPS, and the correlation between the surface state of the substrate and the bonding performance of coating/substrate was inquired into. Results revealed that the preheating treatment resulted in the formation of a dense oxide scale on the surface of Q345 substrate, which composed of an outer layer Fe2O3 and an inner layer Fe3O4. With the prolonging preheating time, the thickness of Fe2O3 layer was almost the same and the inner layer Fe3O4 became thicker, whilst the surface roughness of the substrate changed gradually. The change of the surface roughness of the substrate affected the bonding performance of the coating/substrate system.
