针对压铸锌合金生产中多频次出现导柱漏液问题进行失效解剖分析,采用化学分析法、金相分析法对导柱材质、显微组织及微观缺陷形貌进行甄别。结果表明:导柱材质存在疏松、缩孔、未轧制焊合、轧制不均、夹杂物、偏析、线状缺陷问题,其中组织中线状缺陷、夹杂物周围疏松、缩孔是导致导柱失效漏液的主要原因。 Aiming at the failure analysis of guide column leakage in the production of die-casting zinc alloy, the material, microstructure and microstructure of guide column were identified by chemical analysis and metallographic analysis. The results show that the material of the guide pillar is loose, shrinkage cavity, unwelded, uneven rolling, inclusions, segregation, linear defects, linear defects in the organization, loose inclusions around the inclusions, Failure of the main reason for leakage.
