铜及铜合金带材表面质量控制及技术现状

综述了目前国内高精度铜及铜合金带材表面的质量状况，提出表面物理缺陷和化学缺陷及其概念，描述了带材表面各种缺陷的形貌特征，分析了缺陷产生的原因及关键工序的控制要点；介绍了目前铜带表面质量控制采用的新技术、新材料及表面缺陷量化等技术的应用现状.分析表明，高精度铜带表面质量中起皮、划伤、擦伤和凹坑等表面物理缺陷是产品质量投诉的主要原因，而影响铜带表面质量的因素众多并贯穿于生产的整个过程.加强技术创新和新技术、新材料的应用，提高各工序的产品质量保障能力，同时精细管理、细心操作、采用缺陷量化检测手段是控制表面质量及提升产品品质的关键.

Surface Quality Control and Technical Actuality of Copper and Copper Alloy Strip

It was summarized the surface quality situation of the high accuracy copper and copper alloy strip in this paper.The concepts of surface physical defects and chemical defects were proposed for the first time.It was described the morphology of a variety of surface defects,analyzed the cause of it and key control points to reduce the defects of surface. It was introduced the new technologies,new materials to control the surface defects,and the using actuality of the surface defects quantizing technology.The results show that surface physical defects,example peeling,scratching,pit and other surface physical defects are major cause of complaints in the quality of copper strip.But there are many factors affecting the surface quality of copper,and in the whole process of production. It is necessary to strengthen technological innovation,use new technology and new materials,and improve the security capability of each process.Simultaneously, fine management,careful operation and use testing method of defect quantification are the key for controlling the standard of surface quality,and promoting products quality.
