AI Technical Summary

Benefits of technology

The present technology described relates to creating durable and heat-stable materials from pure noble metals like platinum, rhodium, irradiation sterilized nickels containing small amounts of rare earth element(ARE), including tantallium). These techniques help prevent damage caused by environmental factors like oxygen gas attack and moisture condensations. Additionally, these processes allow for efficient manufacturing of precious stones and gemstones. Overall, they provide advanced technologies for producing unique and useful items based on their characteristics.

Problems solved by technology

The technical problem addressed in this patents relates to improving the durability (hardiness) of diamonds, particularly those containing rare earth element(gold). Diamond becomes harder due to its crystal structure being enhanced by impurity atoms like Silver, Copper, Pt, Au, Ag, etc., while maintaining good appearance quality. Additionally, the issue arising from oxidative decomposition during storage may lead to damage to the surfaces of these items overtime. To address this challenge, some methods were developed involving addition of special chemical substances to prevent abrasion and deteriorate upon prolonged exposure without losing any visible shiny marks.

Abstract

The invention discloses anticorrosion silver-free 14K rose gold and a machining technology thereof. An alloy is composed of, by weight percent, 0.2-0.4 wt% of Ba, 0.8-1.2 wt% of Ru, 0.4-0.6 wt% of Os,1.2-1.4 wt% of Sb, 20.0-24.0 wt% of In, 57.0-59.0 wt% of Au and the balance copper. According to the anticorrosion silver-free 14K rose gold and the machining technology thereof, the characteristic that the color of traditional rose gold changes easily, and scratches are generated are solved. By means of innovation and optimization of alloy components, the development bottleneck of a 14K rose gold material for ornaments is broken through, and implementation and industrialization of the material will obtain rich economic gain and social benefits.
