Abstract:Zn-SiO2 composite coating was prepared by sherardizing with slurry and depositing SiO2 by sol-gel method. The composition, microstructure and phases of coatings were analyzed by EDS, SEM and XRD. The oxidation properties of slurry sherardizing coating and Zn-SiO2 composite coating were studied by a mass-gain method.It is shown that Zn-SiO2 composite coating can enhance the oxidation resistance of sherardizing coating more than three times.
Key words: slurry sherardizing; Zn-SiO2 composite coating; oxidation resistance
