表面铜粉剥离，导致铜杆线表面损伤，其对铜杆线拉伸过程具有较大影响。通过扫描电镜分析，剥离铜粉厚度可达25μm，经物相分析确定其主要成分为铜及铜的氧化物。通过对剥离物和杆线表面缺陷进行形貌分析，以铜杆线的生产、加工各环节作为研究对象，并确认了铜杆轧制工艺、无酸清洗工艺、线表擦伤、拉伸角度及拉丝模具等5方面影响因素，制定了相应的对策措施。研究表明，铜杆氧化物剥落和机械损伤是铜粉剥离的主要原因，在铜杆线生产、加工环节，防止氧化物带入铜基体和避免铜线表面损伤能有效减少铜杆线铜粉剥离。

The exfoliation of copper powders induces the damage of the copper rod and copper wire on surface which has a great influence during the stretching of the copper rod and copper wire. By SEM and XRD analysis, the thickness of the exfoliation can be 25 μm and the main compositions are copper and its oxide. By inspecting and analyzing morphology of the exfoliation materials and surface defects of the copper wire, the production and fabrication process of the copper rod and wire are researched to verify the rolling mill practice, in-acidity process, wire surface wound, stretch angle and wire-drawing die as the five risk factors contribute to surface quality, and to formulate the corresponding measures. The researches show that the main reasons of the exfoliation of copper powders are copper rod oxide exfoliation and mechanical injury. During the production and the fabrication process of the copper rod and copper wire, the effective way to reduce the exfoliation of copper powders on the copper rod and copper wire is to prevent oxide from getting into copper matrix and to avoid the copper wire surface being injured.
