| 摘 要： | 运用QCM反应性监测方法研究了暴露在博物馆模拟展柜中的青铜文物模拟材料的腐蚀行为及规律,并利用扫描电镜(SEM)、能谱仪(EDS)以及光电子能谱(XPS)分析手段,对青铜文物模拟材料在腐蚀60 d后的腐蚀形貌与产物进行了分析。结果表明:光照的存在以及温度、湿度的升高都会加速青铜文物模拟材料的腐蚀,其中ERCO LED灯在色温为4 000 K时对青铜文物模拟材料的腐蚀影响最严重,在腐蚀60 d后的主要腐蚀产物为Cu2O、CuO、SnO、SnO2,还有少量铜的碳酸盐、铜的硫酸盐与铜的硫化物、铜的硝酸盐与亚硝酸盐、铜的氯化物。

| Abstract: | The atmospheric corrosion behavior and law of bronze simulation materials exposed to museum simulation showcase were in situ monitored by quartz crystal microbalance (QCM). The corrosion products formed on surface of bronze simulation materials after 60 d were investigated by means of scanning electron microscope (SEM), energy dispersive spectrometer (EDS) and X-ray photoelectron spectroscopy (XPS). The results showed that adding light, increasing humidity and temperature accelerated the corrosion of bronze. The most serious corrosion of quartz crystal was achieved when exposed to ERCO LED 4 000 K. After exposed to different lights for 60 d, the main corrosion products were Cu2O, CuO, SnO, SnO2 and the secondary corrosion products were copper carbonate, copper sulfate and copper sulfide, copper nitrate, copper nitrite and copper chloride. |
