研究了低碳铁硼铸钢在520 ℃锌浴中的界面形貌和耐蚀性。结果表明，高铬高镍的铁硼铸钢具有最好的耐锌液腐蚀性能。腐蚀层由γ-Fe_3Zn_（10）、δ-FeZn_（10）、xi-FeZn_（13）和η-Zn组成。Fe-B铸钢的腐蚀行为包括以下过程：Cr和Ni的优先浸出和溶解，锌原子扩散控制的Fe-Zn化合物的形成，以及在液态锌腐蚀下，没有α-（Fe，Cr）基体支撑作用的硼化物剥落。皇冠版权所有（C）2011由爱思唯尔有限公司出版。保留所有权利。
The interfacial morphology and corrosion resistance of low carbon Fe-B cast steels in zinc bath at 520 degrees C were investigated. The results show Fe-B cast steel containing high Cr and Ni exhibits the best corrosion resistance to liquid zinc. The corrosion layers are composed of Gamma-Fe3Zn10, delta-FeZn10, xi-FeZn13 and eta-Zn. The corrosion behaviour of Fe-B cast steels includes the following processes: the preferential leach and dissolution of Cr and Ni, the formation of Fe-Zn compounds controlled by zinc atom diffusion, and the spalling of borides without the supporting role of alpha-(Fe, Cr) matrix corroded by liquid zinc.
