Improvement of Corrosion Resistance of Magnesium Alloy by Ce Addition and High Cooling Rate

导出

摘要通过在3.5%NaCl溶液中的重量损失试验,研究了Ce含量对AZ91镁合金耐腐蚀性的影响。此外,对比研究了快淬和普通铸态条件下镁合金的防腐性能。结果表明,加入Ce可以显着提高AZ91镁合金的耐腐蚀;快速冷却可以通过细化晶粒和改变形态以提高耐腐蚀性。通过在3.5%NaCl溶液中的重量损失试验,研究了Ce含量对AZ91镁合金耐腐蚀性的影响。此外,对比研究了快淬和普通铸态条件下镁合金的防腐性能。结果表明,加入Ce可以显着提高AZ91镁合金的耐腐蚀;快速冷却可以通过细化晶粒和改变形态以提高耐腐蚀性。
