研究了新型Fe-Cr-Mo-B铸钢在铝液中的耐蚀性能和界面形貌。结果表明，硼化物，特别是初生富铬Fe2B，对提高Fe-Cr-Mo-B铸钢的耐腐蚀性能起关键作用。它们嵌入金属间化合物（铁基体的腐蚀产物）中，并作为根有效防止金属间化合物脱落。 Fe-Cr-Mo-B铸钢在铝液中的耐腐蚀性能比H13高5倍。
The corrosion resistance and interfacial morphologies of novel Fe-Cr-Mo-B cast steels in molten aluminum have been studied. The result indicates that borides, especial the primary Cr-rich Fe2B, play a key role in improving the corrosion resistance of Fe-Cr-Mo-B cast steels. They are embedded in the intermetallics (corrosion products of the Fe substrate) and act as root to prevent the intermetallics from falling off effectively. The corrosion resistance of Fe-Cr-Mo-B cast steel in molten aluminum is 5 times higher than that of H13.
