Fe-B共晶合金在锌液中的腐蚀行为
Corrosion Properties of Fe-B Eutectic Alloy in Liquid Zinc
摘 要
在500℃的锌液中,对Fe-B共晶合金进行恒温静态腐蚀试验.对其腐蚀动力学和基体/Zn腐蚀界面进行研究,探讨了Fe-B共晶合金在锌液中的腐蚀过程和机理.结果表明,Fe-B共晶合金有比较好的耐锌液腐蚀性能:锌液腐蚀基体的过程是Fe原子和Zn原子相互扩散的过程:扩散导致新相的形成,在热应力和锌液冲击应力以及新相生长的拉应力的作用下,腐蚀层产生裂纹断裂并溶解.腐蚀以此方式反复进行,最终导致合金失效.

Abstract
The static isothermal corrosion tests on Fe-B eutectic alloy were performed in liquid zinc at 500 ℃.The process and mechanism of corrosion has been explored by studing corrosion kinetics and interface of matrix and Zn.The results showed that corrosion resistance of Fe-B eutectic alloy in liquid zinc was good.Corrosion of Fe-B eutectic alloy resulted from the inter-diffusion of Fe and Zn atoms.Cracks emerged on corrosion layer were caused by thermal stress and wallop of zinc.The corrosion products were dissolved by zinc ultimately.
