英文摘要	The enamel coatings sintered at 700-900 were prepared on the surface of Q235 low carbon steel by one-time coating enamel method. Phase composition, morphology, micro-area composition, mechanical properties and corrosion behavior of enamel coatings were investigated by XRD, SEM, EDS, micro Vickers hardness tester, ball dropping device and electrochemical workstation. Results show that the surface porosity decreases gradually, while the cross-section porosity decreases at first, then increases and final decreases during the sintering process. The grinding additive quartz dissolves gradually in the silicon-oxygen tetrahedron [SiO4] network of the coating, which improves the micro-hardness and gloss of coating. The oxide layer at the interface between coating and matrix decreases and disappears eventually, while the diffusion zone of Fe enlarges gradually, and a dendrite-rich of Fe-Co and Fe-Ni dendrite layer is formed. The formation of enamel layer and the closure of internal corrosive channels of the coating significantly improve the corrosion resistance. © 2020, Editorial Office of CHINA SURFACE ENGINEERING.
