中文摘要：

采用腐蚀失重试验和动电位极化曲线扫描测试手段,研究Ce元素对Pb-Mg-Al合金在3.5%（质量）NaCl溶液中腐蚀性能的影响。研究结果表明：随着Ce含量的增加,稀土Ce与合金中的Al形成弥散、均匀的金属间化合物Al4Ce,进一步提高了合金的耐蚀性。

英文摘要：

Effects of Al and Ce addition on corrosion behavior of Pb-Mg-Al alloys were studied in 3.5% NaCl solution by measuring the weight loss in solution and simultaneously measuring electrochemical polarization curves.The results indicated that,with the increase of Ce content,the dispersion,uniform inter-metallic compounds Al4Ce formed by the rare earth element Ce and Al,the corrosion resistance of the alloy is further enhanced.
