Effect of Sintering Temperature on the Microstructure, Corrosion Resistance and Crack Susceptibility of Chemically Reactive Enamel (CRE) Coating

Abstract

The microstructure, corrosion resistance and crack susceptibility of chemically reactive enamel (CRE) coatings applied on steel bar with different sintering temperatures were investigated in this study. As the sintering temperature increases, the CER coating structure becomes dense, the extent of chemical reactions between coating and steel gradually increases, and the corrosion resistance of CRE-coated rebar becomes higher in both short-term and long-term corrosion tests. Compared with uncoated steel bar, CRE coating can effectively delay the development of steel corrosion. CRE coating sintered at 750 °C shows the lowest crack susceptibility amongst all coatings.
