Investigating the Influence of Li2Co5O10 as Mill Addition on Adherence of Enamels for Steel A283 (C) used in Oil Pipes and Containers

In this paper, Li2Co5O10 was synthesized by a solid reaction and controlling nucleation and crystal growth time. The enamels adherence greatly increased by adding this powder as mill addition. The influence of this additive was studied by investigating chemical composition and microstructure of enamel-steel interface by using scanning electron microscopic (SEM). The distribution of Co, Fe and Si was also studied by point and line scan analysis. The results revealed that the superfine powder can change the composition and microstructure of the interface and promote the adherence of enamel tosteel. Adherence of samples was examined by standard test method ASTM B916 and the optimum amount of the additive was observed to be 1.8 %wt. J. Color Sci.
