摘要
世界铸币、展览、收藏等领域的银及其合金器件存在变色问题,现代工业中与银有关的部件的服役寿命、性能稳定性等一直被其变色困扰。为此,对银在氧、硫化氢、硫、二氧化硫、有机硫化物、氮氧化物、硫化物溶液、自由基和过氧化物、氯化物等腐蚀介质中的变色历程的研究进展进行了综述,概括了湿度、温度、光照、表面状态等因素对银变色的影响,提出了银变色研究面临的挑战和发展的方向。
A review is provided of research progress about the tarnishing process of silver in corrosive mediums including hydro-gen sulfide,sulfur,sulfur dioxide,organic sulfur,NO2,free radical,sulfur liquor and chloride.The effects of temperature,humidity,illumination and surface state on the tarnishing of silver are summarized.It is pointed out that the wares made of silver and its alloys in the fields of mintage,exhibition and collection are always facing the problem of tarnishing which also causes damage to the service life and performance stability of the ele-ments made of silver in modem industry.Moreover,the challenge and development trend of the research on tarnishing of silver aresuggested.
