基于CT无损检测的脆弱青铜器腐蚀评估

Disease Assessment of Fragile Bronzes Through CT Nondestructive Testing

目前对脆弱青铜器的分析主要依赖于对样品横截面、表面等二维层面的研究,如光学和电子显微镜、拉曼光谱分析、X射线荧光光谱分析(XRF)等。CT作为一种快速、无损的检测手段,可以对青铜器的内部结构、腐蚀情况、腐蚀分布等作出更详细的表征和检测。本文从青铜器腐蚀定性观测、青铜器腐蚀分层提取、青铜器腐蚀特征提取与分析等方面,通过分析脆弱青铜器的CT成像结果,实现对脆弱青铜器中内部腐蚀进行分析、定位和测量,为脆弱青铜器的腐蚀评估与保护研究提供数据支撑,进一步验证CT技术在文物保护领域的重要价值和应用前景。

Current analysis of fragile bronzes mainly relies on the research of two-dimensional aspects such as sample crosssections and surfaces while typically utilizing optical and electronic microscopy,Raman spectroscopy,and X-ray fluorescence spectroscopy(XRF).As a fast and nondestructive testing method,computer tomography(CT)can be used to characterize and detect the internal structures,corrosion conditions,and corrosion distribution of bronzes.This study used the CT imaging results of fragile bronzes to analyze,locate,and measure corrosion in fragile bronzes quickly and accurately,thus providing strong support for corrosion evaluation and protection research of fragile bronzes.The results verified the value and application prospects of CT technology in the protection of cultural relics.
