徐阳墓地出土青铜器焊料的检测分析

利用金相显微镜、扫描电镜能谱对洛阳徐阳村墓地西区出土的一件铜盘连接处的焊料进行检测分析，并且与目前已经公布的西周晚期到战国晚期的焊料成分的研究成果进行比较。西周晚期至春秋晚期出土的焊料有铅焊料、锡焊料以及铅锡合金焊料，而铅锡合金焊料以高铅低锡型合金较为常见。与春秋时期的铅锡合金焊料相比较，战国时期的铅锡焊料中同样以高铅低锡型合金较为常见。研究表明，徐阳墓地出土的铜盘连接处焊料为纯铅焊料，与春秋时期铅焊料、锡焊料及铅锡合金焊料的特征相吻合，因此认为徐阳墓地出土焊料为春秋时期的焊料。

Analysis of a Bronze Solder Excavated from the Xuyang Cemetery

Solder from a bronze plate joint excavated from western part of the Xuyang cemetery in Luoyang city was analyzed by metallurgical microscopy and scanning electron microscopy energy spectroscopy, and compared with published research on solder from the late Western Zhou to late Warring States periods. Solders unearthed from the late Western Zhou to late Spring and Autumn periods includes lead, tin and lead-tin alloy solder, with lead-tin alloy solder being the most prevalent, which is high lead and low tin alloy. Compared with lead-tin alloy solder from the Spring and Autumn period, the lead-tin alloy solder from the Warring States period is also more common in the high-lead, low-tin alloy type. The results show that the solder at the joint of the bronze plate excavated from the Xuyang cemetery is pure lead solder, which is consistent with the characteristics of solder from the Spring and Autumn period. Therefore, it is suggested that the solder excavated from the Xuyang cemetery could dated back to the Spring and Autumn period.
