摘　　要：硬度是反映材料耐磨性的一个重要指标,黄金首饰,尤其是高成色黄金首饰,除传统足金外,还有“3D”硬金、“5G”黄金及“古法”金首饰。查阅已发表的关于黄金首饰硬度的相关文献,并结合多年积累的黄金首饰维氏硬度数据,总结了常见足金和彩色18K金首饰的硬度,可为评价各类黄金首饰的耐磨性提供数据支撑。同时,参考金属材料的经典强化机制,结合各类首饰的加工工艺,分析了常见黄金首饰的硬化机制。Hardness is an important index for evaluating the wear resistance of materials.In addition to traditional pure gold,gold jewelry,especially high-carat gold jewelry,includes"3D"hard gold,"5G"gold,and"ancient method"gold.By consulting relevant literature on the hardness of gold jewelry published and combining years of accumulated Vickers hardness data of gold jewelry,the hardness of common pure gold and colored 18K gold jewelry is summarized to provide data support for evaluating the wear resistance of various types of gold jewelry.At the same time,referring to the classic strengthening mechanism of metal materials and combining it with the processing technology of various jewelry,the hardening mechanism of common gold jewelry is analyzed.
