| 中文摘要: |
| 喷砂处理工艺可在金饰品表面产生哑光效果，耐久美观，但也会使得X射线荧光光谱(XRF)测定时出现较大的偏差。分别在宏观与微观下进行表面观测，采用XRF和火试金对18K金饰品材料和成品进行对比测定，研究其表面成分和形貌的差异。结果表明，样品表面存在酸反应痕迹，部分元素(主要是合金中的铜)在酸洗过程中有损失。 |
| 英文摘要: |
| The sand blasting process can produce matte effect on the surface of gold jewelry, which is durable and beautiful, but The sand blasting process also causes large deviation in X-ray fluorescence spectroscopy (XRF) measurement. The surface observations were carried out under macroscopic and microscopic conditions respectively. The 18K gold jewelry materials and finished products were compared and measured by XRF and fire test, and the differences in surface composition and morphology were studied. The results show that there are traces of acid reaction on the surface of the sample, and some elements (mainly copper in the alloy) are lost during the pickling process. |
