【摘要】 为了探讨铜盐等腐蚀产物对青铜器腐蚀的影响,采用腐蚀膏试验和微电极测试腐蚀电流的方法研究了氯化亚铜、碱式氯化铜、碱式碳酸铜等对青铜试片和铜电极腐蚀的影响,得出氯化亚铜是加速青铜器腐蚀的最有害物质的结论。红外光谱分析表明,以苯骈三氮唑为主钝化剂的高效防护剂同时改变了氯化亚铜的结构,起到了有效抑制青铜器腐蚀的作用。应用电位活化理论阐述了青铜器粉状锈小孔腐蚀的电化学行为,提出了氯化亚铜加速青铜器腐蚀的多孔氧电极催化模型。更多还原

【Abstract】 In order to explore the corrosion of bronze,the effect of copper chloride,copper chloride alkali and copper carbonic acid alkali on the corrosion of bronze samples and copper electrode was studied by corrosion paste experiments and microelectrode methods. The results indicated that the copper chloride was the most harmful material for accelerating bronze corrosion. According to infrared spectroscopy (IR) analysis indicated that high - efficient protection agent, whose main passivation additive was BTA, could changed the structure of copper chloride, and consequently resulted in effectively restraining bronze corrosion. The electrochemical reaction of the potting corrosion on bronze was expatiated by applying "potential activation" theory,and a catalysis model of the porous oxygen electrode of copper chloride accelerating the bronze corrosion was proposed.更多还原
