摘　　要：本文使用X射线衍射(XRD)、离子色谱(IC)、光学显微(OM)及显微红外光谱(Micro-FTIR)等分析手段,对故宫灵沼轩建筑金属构件的锈蚀产物样品进行了分析,并结合相关研究成果探讨了构件的病害成因及影响因素。研究表明,钢铁质构件的主要锈蚀机理为大气环境下的电化学腐蚀,其所处的外部环境及自身的材质、加工特点,均可对锈蚀程度产生影响;而金属构件的断裂、变形,除了构件自身的材料特性外,还与其承受的构造应力、环境高低温交变以及不恰当的填充材料有关。By X-ray diffraction (XRD), ion Chromatography (IC), optical microscope (OM) and micro-Fourier transform infrared spectroscopy (Micro-FTIR), the analysis of the iron and steel components for the structure of Lingzhao Xuan of the Imperial Palace arrives at the following conclusion in this thesis: The mechanism for extensive corrosion on the architectural components exist in the electrochemical corrosion under atmospheric environment. The external environment, materials and processing features should be partly responsible for the rusty metal objects. As far as the fracture and distortion of the components is concerned, they are linked with materials, tectonic stress upon them, temperature differences of environment, inappropriate filling stuff as well.
