摘要
应用电位活化理论分析和阐述了青铜器腐蚀的观点和防护理念。对青铜器腐蚀的全过程提出了致密膜保护期、保护膜破坏局部腐蚀期和小孔腐蚀粉状锈加速期三个阶段的看法。用高效钝化保护剂对处于不同腐蚀阶段的青铜器保护膜进行修复和改性 ,结果表明 ,理论腐蚀电阻RC 从 10 5Ω提高到 10 7Ω ,并具有可间断涂覆、可回复的特点 ,可应用于青铜文物的保护试验。
The current situations of the research of bronze corrosion and protection were stated simply.The potential activation theory was applied to analyze and expound the viewpoints of bronze corrosion and protection.The whole processes of bronze corrosion were divided into three phases:compact membrane protection phase,protection membrane damaged local corrosion phase and pore corrosion powdery rust accelerated phase.The recent research results of efficient passivation protection agent were reported.With this passivation agent,the protection membrane of different corrosion phases were restored and changed property,and its corrosion resistance was enhanced from 105Ω to 107Ω and it may be coated discontinuously and restored.Currently it was applied to protection test of bronze cultural relic.
