摘　　要：通过对2024-T3铝合金板材表面缺陷的宏微观形貌观察、能谱分析、金相检查,粗糙度检测,对表面缺陷性质和成因进行了分析。结果表明:其表面缺陷为长期存放于湿度高、温差大环境中导致的大气腐蚀;根据缺陷形成原因,制定了消除表面缺陷措施并提出了相应改进建议。The properties and causes of surface defects of 2024-T3 aluminum alloy platewere analyzed by macro and micro morphology observation,energy spectrum analysis,metallographic examination and roughness detection.The results show that the surface de-fects of aluminum plate are atmospheric corrosion caused by long-term storage in the environ-ment with high humidity and high temperature difference;according to the causes of defects,the surface defects removal measures are formulated and corresponding improvement sugges-tions are put forward.
