摘要 传统足金/Au999在黄金首饰消费中占据了最大份额,它们具有高贵的黄色和优异的耐蚀性,但硬度过低的问题制约了饰品的艺术价值,也给制造和使用带来了问题。该文采用钴、锑、钪对足金进行了多元微合金化处理,并采用人工汗液浸泡法和电化学试验法检测了合金的腐蚀倾向和抗变色性能。试验结果表明:改性足金的初始颜色与Au999之间的色差仅处于肉眼可觉察的区间,它在人工汗液中的颜色变化率与其所处状态有关,呈现"形变时效态>固溶态>冷形变态"的顺序。改性足金在人工汗液中存在钝化行为,耐点蚀性能与Au999相当,表现出优良的抗变色性能。 Traditional pure gold/Au999 jewelry has the noble yellow glows and excellent corrosion resistance and accounts for the biggest share in gold jewelry consumption,however,its low hardness restricts the artistic value and brings problems in manufacture and application.In this paper,pure gold was multi-alloyed with cobalt,antimony and scandium,and the corrosion tendency and the anti-chromism property of the modified gold were tested by artificial sweat soaking and electrochemical method.The results show that the original chromatic aberration of the modified gold from pure gold is only discernible between the range of naked eye,and the color change rate after soaking in artificial sweat is related to its state,which shows the order "cold working and aging state〉solid solution state〉cold working state".The modified gold presents passivation behavior in artificial sweat,its pitting corrosion resistance is close to pure gold and shows excellent discoloration resistance.
