Problems solved by technology

But so far, a suitable composition and solution have not been found
Similarly, although a layer of TiCN and other coatings are plated on the surface of rose gold to improve wear resistance, it only prolongs the service life to a limited extent and does not fundamentally solve the problem.

Abstract

The invention discloses corrosion-resistant 10K rose gold without silver and a processing technology of the 10K rose gold. Components of the alloy comprise, by weight percentage, 0.6-0.8 wt.% of Li, 1.0-1.5 wt.% of Rh, 0.3-0.5 wt.% of Ta, 0.1-0.4 wt.% of Pr, 30.0-32.0 wt.% of In, 40.0-42.0 wt.% of Au and the balance copper. The invention provides the novel 10K rose gold without silver and the processing technology of the 10K rose gold. The characteristics that color fading and surface scratches happen in use of traditional rose gold are avoided. Due to innovation and optimization of the alloycomponents, the developing bottleneck of a 10K rose gold material for jewelry is broken through, fruitful economic gain and social benefits can be obtained during implementing and industrialization ofthe material.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a gold alloy. Background technique [0002] Gold is very soft and can be set into a variety of exquisite styles, especially for pearls, gemstones and emeralds. In order to enhance the hardness of gold, people add a small amount of silver, copper, zinc and other metals to gold to increase the strength and toughness of gold, and the gold ornaments made in this way are called K gold. The gold level standard K, which indicates the content of pure gold in gold products, generally refers to pure gold as 24K gold, but it is gold with a theoretical gold content of 100%, and does not actually exist. Therefore, in the national standard, merchants must not use the non-standard method of 24K gold to mark the gold content of gold jewelry. 1K means that gold products contain 1 / 24 of pure gold, about 4.16%, 18K gold means that the gold content is 75%, and the rest are alloying elements.
