摘要
介绍了一种利用表面 X 射线荧光 (XRF) 数据估算历史和考古文物中金属内核成分的方法。该方法利用金属合金中惰性成分脱金属的普遍现象，将物体不同腐蚀程度点上记录的荧光数据进行组合。利用约翰逊-梅尔-阿夫拉米-埃罗费耶夫-科尔莫戈罗夫（JMAEK）形式主义提供了一种理论方法来描述脱金属现象。来自因斯布鲁克 Hofkirche 的二元锌铜黄铜以及含铅和锡黄铜的实验数据与模型完全吻合。
Determining of the composition of the metallic core of historical objects from surface XRF spectrometry data
A method for estimating the composition of the metal core in historical and archaeological artifacts using surface X-ray fluorescence (XRF) data is described. The method is based on the combination of fluorescence data recorded at points of the object with different degrees of corrosion exploiting the general phenomenon of demetallation of the less noble components of the metal alloy. A theoretical approach is provided using the Johnson–Mehl–Avrami–Erofeev-Kolmogorov (JMAEK) formalism to describe demetallation. Experimental data for binary ZnCu brass and Pb- and Sn-containing brass from Hofkirche in Innsbruck agree satisfactorily with the model.
