［Objective］To address the issues of insufficient high-temperature resistance and poorcorrosion resistance of traditional protective coatings for waste incineration boilers.［Methods］A new type of anti-coking and anticorrosive coating was developed based on the synergistic effect of hybridmetal oxides and modified silica sol-gel. The coating structure was characterized by Scanning ElectronMicroscopy（SEM）， X-ray Diffractometer（XRD）， and Fourier Transform Infrared Spectrometer（FT-IR）. The comprehensive performance of the coating was investigated by pencil hardness testing，drop-weight impact testing，high-temperature sintering and salt spray corrosion tests.［Results］The pencil hardness of the coating reached 4H，the impact resistance was 63 cm，and it could withstand sintering at 1 800 ℃. The coating was not affected in the 39-day salt spray test.［Conclusion］Hybridmetal oxides combined with modified silica sol-gel can significantly improve the anti-coking andanticorrosive performance of the coating.
