摘要:

利用一种新型的盐溶液-蒸汽模拟技术,在过量CO₂的气氛环境中模拟生成孔雀石等锈蚀产物,并利用光学显微镜、扫描电子显微镜、能谱仪、X射线衍射仪、Raman光谱仪等表征仪器,系统表征了锈蚀产物的微观组织和化学成分等。研究分析了在不同过量CO₂的气氛环境下,青铜表面生成锈蚀产物的特征及其生长机理,为古代青铜器的保护提供了科学依据。

Abstract：

The formation of rusts consisted mainly of malachite on bronze was simulated with a new process, by which the corrosion test of bronze samples was performed in controllable environments with excess of CO₂ contents, water vapor and chlorine ions. The chemical composition, microstructure and phase constituents of the corrosion products were characterized by means of optical microscopy, scanning electron microscope (SEM) with energy dispersive spectrometer (EDS), X-ray diffraction (XRD), and Raman microscopy. The results revealed that the characteristics of corrosion products were related with the content of CO₂ and H₂O in the environment. The growth mechanism of the rusts in these environments was discussed and the suggestions for preservation of the ancient bronzes were proposed.

Key words： bronze malachite corrosion product CO₂ atmosphere environment
