Many coating technologies have been developed so far to improve the corrosion resistance, strength, abrasion resistance and other surface properties of materials and equipment. Among them, the formation of CCO (CaCoO, then CCO) thin films has been studied and used in the electronic material field. One of the characteristics of CCO thin films is that it is resistant to high temperature heat. Particularly, the method of forming the CCO thin film is relatively simple, and it was judged that it could be introduced into the existing equipment. Therefore, in this study, an experiment and analysis were carried out to determine whether the coating of CCO thin films can be applied to hot dip galvanizing facilities. A CCO thin film was formed on the surface of STS304 base material and oxidized in a Zn fume atmosphere in a $650^{\circ}C$ furnace with an air atmosphere. Oxidation was carried out for 30 days, after which the shape of the CCO thin film was confirmed by SEM and its corrosivity was analyzed through a potentiodynamic polarization experiment.
