摘要(Abstract)：

研究了阳极氧化工艺和表面液相偏析层对半固态成形ZL114A合金铸件耐蚀性的影响。结果表明：对于阳极氧化而言，表面液相偏析层会显著影响氧化膜生长速率，使得氧化膜厚度减小，但由于膜层平整，反而有利于氧化膜对合金耐蚀性能提高；然而，去除表面液相偏析层虽然会增加试样表面氧化膜的厚度，但由于这种氧化膜分布不均匀，从而无法提高合金的耐蚀性。未经阳极氧化处理的试样耐蚀性分析结果表明，表面液相偏析层的存在会降低试样的耐蚀性，去除表面液相偏析层会在一定程度上提高耐蚀性。对氧化膜腐蚀后的蚀坑研究发现，共晶组织对氧化膜的蚀坑的形成起着决定性作用，蚀坑通常位于共晶组织部位，且在蚀坑中往往发现有富铁金属间化合物。
