摘要

为了研究分析汽车空调用3003 铝管穿孔失效的原因，采用宏观形貌分析、化学成分分析、扫描电镜微观形貌分析以及能谱分析方法对3003 铝管表面孔洞缺陷进行研究。结果表明:3003 铝管表面存在的非金属夹杂破坏了铝管表面的完整性和连续性，使得夹杂处不能形成致密的氧化膜，在强腐蚀性元素Cl 和S 的共同作用下，导致3003 铝管出现点蚀穿孔失效。建议在3003 合金熔炼过程中控制精炼剂的加入量，并增强铝液中夹杂的过滤效果，同时改善铝管表面清洁度和仓储环境。本研究成果可为3003 铝管的制造提供一定的参考。

Abstract

In order to study and analyze the causes of perforation failure in 3003 aluminum tubes， used in automobile air conditioning， the reasons for surface perforation defects in these tubes were investigated.This investigation involved macro-morphology analysis，chemical composition analysis， scanning electron microscope micro-morphology analysis and energy spectrum analysis.Results showed that nonmetallic inclusions on the surfaces of the 3003 aluminum tubes damaged the integrity and continuity of these surfaces.This issue prevented the formation of a dense oxide film at the inclusion sites.Under the combined influence of the strongly corrosive elements chlorine (Cl) and sulfur (S)， pitting and perforation failures occurred in the 3003 aluminum tubes.It was suggested that the addition of refining agents should be carefully controlled during the melting process of the 3003 alloy.Additionally， improvements in the filtering of inclusions in the aluminum liquid， as well as enhancements in the surface cleanliness and storage environment of the aluminum tubes， were recommended.These research findings could provide a certain reference for the manufacturing of 3003 aluminum tubes.
