装饰铜合金防变色工艺研究进展

Research Progress of Anti-Tarnish Techniques of Decorative Copper Alloys

装饰铜合金应用广泛,但变色问题是制约其发展的一个关键因素。分析论述了抗变色装饰铜合金在实际应用中出现的问题以及铜合金的变色机理,从添加合金元素和抗变色技术手段等方面阐述了装饰铜合金的防变色方法,并展望了防变色铜合金应用于民用建筑、医学等领域的发展前景。

Decorative copper alloys are widely used,but the color change problem is a key factor of restricting its development.In this paper the problems in practical application about anti-tarnishing decorative copper alloy and the preparation principles of glossy fading resistance of decorative copper alloy were discussed.Moreover,the anti-tarnish ways of decorative copper alloy were analyzed in aspects of adding alloy elements and various anti-tarnish technological methods.Finally,the trends and prospects of the anti-discoloration process used in civil buildings and medicine field were put forward.
