造币铜合金材料设计原则与研究进展

Design Principles and Research Status of Coinage Copper Alloy Materials

铜合金是造币材料中应用最为广泛的材料之一,随着经济社会的快速发展以及人们对造币合金色泽要求越来越高,研究和开发应用造币铜合金越来越广泛,主要有流通币、纪念币、印章等。采用CIELAB均匀色空间定量描述合金色泽,并对国内外常用的造币铜合金进行归纳总结,阐明造币合金表面色泽的形成机理及影响因素,分析不同色泽造币铜合金的设计原则与研究进展,展望造币铜合金材料的发展方向。

Copper alloy is considered as the widely used materials in the mintage.Following the rapid development of the economical society and the color of mintage were becoming higher and higher.Study and development of copper alloys were becoming more and more widely,including circulation coin,commemorative coin,signet and so on.CIELAB uniform color space was used to describe the color of alloy.The common copper alloys coin at home and abroad were summarized.The formation mechanism and influencing factors of the surface color of the mintage alloy were analyzed,and the design principles and research summaries of copper alloys with different color coinage were analyzed.The future development direction of the copper alloy was expounded.
