摘　　要：气相缓蚀剂应用于带锈铁质文物保护是一种简单有效的方法。本研究通过对WB-1气相缓蚀剂处理前后带锈钱币的形貌检测,并结合XRD、XPS、SEM等手段对该缓蚀剂在带锈钱币表面的成膜方式进行了分析研究。结果表明,WB-1气相缓蚀剂能通过化学吸附作用在带锈铁质钱币表面形成一层保护膜,阻挡有害离子向铸铁文物内部的渗透,并促进带锈铁质钱币表面锈层组分向更为稳定的组成转变。WB-1气相缓蚀剂对带锈铁质钱币具有良好的保护效果,且不改变文物外观,符合文物保护要求。The use of corrosion inhibitors is now an effective way to protect iron coins.The volatile corrosion inhibitor,compound WB- 1,was studied in terms of inhibition performance,and by X- ray powder diffraction,X- ray photoelectron spectroscopy and scanning electron microscopy.This study showed that WB- 1 can be adsorbed and form a film on the surface of rusty iron coins so as to prevent harmful ions from permeating into the coins.Moreover,it can accelerate the transformation of rusty scale and had good inhibition performance for rusty iron coins without changing the appearance of the relics,thus meeting conservation demands.
