摘　　要：在保持黄金较高纯度的同时提高足金首饰的硬度以满足市场消费者和加工两方面需求,一直都是黄金首饰行业内一个重要的研究内容。本文综述并借鉴了传统金属材料的强化机制,从组织、位错的角度,分析了目前足金硬化工艺所蕴含的硬化机制。同时为更好地对硬度性能进行表征,选用维氏硬度试验进行测量,并针对电铸硬金试样测试难度大的问题进行了探索。另外,还统计了目前市场中硬金产品的硬度值,并就工艺对其硬度产生的影响进行了研究。It should maintain a high purity while improving the hardness of solid gold jewelry to meet the demand for both consumer and processing,which has always be a important research in the gold jewelry industry.This article summarizes and draws on the strengthening mechanism of traditional metal materials.Form the perspective of the organization and dislocation,the hardening mechanism is analyzed which is contained in the gold hardening process at present.To be better on characterize the hardness of the performance,Vickers hardness test is chosen for measurement.And it was studied for the difficult problem of electroforming hard pure gold hardness test.In addition,the hardness of the hard gold products in the market is also measured,and influence of the process on its hardness is studied.
