摘要: 基于模型分析,研究了镀金可伐引线在各种缺陷组合方式下的偶合系统在静、动态3％NaCl溶液中的腐蚀行为。应用OCC理论阐述了蚀孔的形成和形貌特征。大气环境下镀金可伐引线的腐蚀是以偶合腐蚀为起因,具有闭塞小孔腐蚀特征的局部腐蚀。中性介质的实验结果与实际断腿样品在形貌等各方面均十分相符,这支持了上述观点。

Abstract：The authors have undertaken the analysis of defects in electrodeposited coatings of Au and Ni on Kovar lead of transistors. The corrosion behaviour of Au and Ni plated lead in 3％ NaCl solutions (aerated or not) has been studied. Results point out that under the atmospheric condition, localized corrosion of Au and Ni plated lead is caused by galvanic couple and possessesthe characteristics of occluded hole. Experimental results in fracture morphology etc. show good agreement with the failure of lead in service.
