Preparation Process of Antioxidation Coating of Prebaked Carbon Anode Steel Claw

In this paper, the preparation and antioxidant properties of SnO2 coating of steel claw of prebaked carbon used as electrolytic aluminium anode was investigated. A denser SnO2 coating on steel claw was prepared by high temperature glaze method . Phase Analysis , microstructure and chemical composition of the steel claw antioxidant coating were by Japan Rigaku D/Max2200 type X-ray diffraction, the Philip XL30 ESEM and EDS. the Oxidation resistance experiments results showed that the better anti-oxidation coating has a optimal thickness size of about 0.4mm.
