摘要
本文综述目前国内外学者对古代青铜器表面高锡锈层的研究状况,从锈蚀的表观形貌特征、成分物相、分层结构、耐腐蚀机理、形成条件与机理、呈色机理等方面总结了前人的研究成果。该类锈层主要化学成分包括Sn,其次为Cu,还含少量Pb、Fe、Si、Al等元素,主要物相为纳米级的微晶或非晶SnO2,可能存在原子掺杂。表面形成高锡锈层的原因以自然腐蚀说为主流观点,可用选择性腐蚀机理来解释。本文还尝试提出目前青铜器表面高锡锈层研究中存在的不足和未来研究中需要重点关注的问题。
This paper gives an overview of the study of tin-rich patina on the surface of the ancient bronzes.It has been summarized from the aspects of surface morphology,material characteristics,chemical composition,corrosion resistance,formation mechanism as well as chromogenic mechanism.According the previous study,the patina mainly contains Sn,a few of Cu and minor amount of Pb,Fe,Si and Al.The primary phase of the patina is nano-sized tin oxide(SnO2),with possibly atomic doping.This patina is more likely to be a natural product rather than man-made corrosion,which can be explained by selective dissolution mechanism.The limitation of the previous research has been pointed out and the problems need to be further explored have been underlined.
