| 摘 要： | 选用升丽婷香港有限公司生产的橄榄绿色、绿色、蜜黄色、浅褐色、橙色、绿蓝色、蓝色、粉色、淡粉色、亮红色10种颜色的TCF托帕石作为研究对象,并结合市场上出现的辐照、扩散、镀膜处理托帕石作为对比,通过设计耐久性实验,对样品表面的耐久性进行了系统的分析研究。实验表明,在耐腐蚀性方面,TCF样品能在较长的时间内浸泡于酒精、洗涤灵、洗衣粉、白醋、纯碱（碳酸钠）、84消毒液、二碘甲烷、洁厕灵、洗银液试剂中不被腐蚀,其耐腐蚀性强于镀膜样品的;在耐高温方面,TCF样品能耐住900℃以上的高温,其耐热性强于辐照处理及镀膜样品的;经耐刻划实验,得出其摩氏硬度为：5〈TCF样品≤6,高于镀膜样品的。

| Abstract: | Ten colours of TCF topaz samples which are produced by Signity Hongkong Company Ltd.,i.e.olive green,green,yellow,sandy beige,orange,greenish-blue,blue,pink,light pink and bright red as subjects in the research.Through the comparison with the topaz by irradiation,diffusion and coating treatments,the durability experiments are carried out to make a systematic analysis.The results show that in terms of the corrosion resistance,TCF samples could be immune to corrosion when dipped in alcohol,detergent,washing powder,white vinegar,alkaline,84 disinfectant,diiodomethane,toilet cleaner and silver washing liquid for a long period,which are better in corrosion resistance than the coated samples.In terms of the high temperature resistance,TCF samples could resist temperature of more than 900 ℃,whose resistance is better than that of the irradiated and coated samples.Concluded from the scratching resistance experiment,the Mohs＇hardness of TCF samples is： 5TCF samples≤6,higher than that of the coated samples. |
