中文摘要：

将镁锂合金浸渍于高温的苯溶液中，使其发生反应并在基体上形成碳化物膜层，采用SEM、XRD等分析了膜层的组织和结构，利用失重法、析氢法和盐雾腐蚀等研究了膜层的耐腐蚀性能．结果表明，利用苯作为浸渍液时，合金表面生成的碳化物涂层比较稳定，不易被腐蚀，使镁锂合金的耐腐蚀性能明显提高．

英文摘要：

Carbide surface film for Mg-Li alloy was prepared through the reaction between Mg-Li alloy and benzene at high-temperature. The microstructure of the film was measured with SEM and XRD. The properties of corrosion resistance were also analyzed by weight-loss method, hydrogen evolution experiment and salt spray corrosion. The results show that, through dipping the Mg-Li alloy into benzene, the carbide coating of alloy is stable and has good property of corrosion resistance.
