摘要	The effect of CoO and NiO on the adherence between enamel coating and steel is investigated experimentally in this study. Enamel coatings are applied to the steel using a wet process with slurries. A total of five enamels were prepared including three single layer enamels: blank enamel (BL), NiO bearing enamel (MTNi3), CoO bearing enamel (MTCo3), and two double layer enamels: BL-MTNi3, BL-MTCo3, which consisted an inner layer of BL and an outer layer of MTNi3 or MTCo3. Falling-weights tests were performed and the cross-sections at the enamel/steel interface were analyzed with a scanning electron microscopy (SEM) coupled with an energy dispersive spectroscopy (EDS) and electron probe microanalysis (EPMA). Results show that the increases of adherence for MTCo3 and MTNi3 coated steel are attributed to the micro-alloys precipitation at the enamel/steel interface. These micro-alloy precipitations grow parallel to the steel/enamel interface for MTNi3, while they are dendritic and perpendicular for MTCo3. Compared with MTCo3, the negative reaction energy between NiO and FeO for MTNi3 causes micro-alloy precipitations formed far away from the enamel/steel interface, resulting in different morphology and adherence.; The effect of CoO and NiO on the adherence between enamel coating and steel is investigated experimentally in this study.
