| titleOfInvention | V-N steel hard pure gold and preparation method thereof |
| abstract | The present invention provides a kind of hard pure gold material for solid gold jewelry, and its constituent mass ratio is：Calcium 0.1~0.4%, titanium 0.5~0.8%, rare earth element 0.01~0.1%, remaining is gold, and gold content is more than 99.0%.In preparation process, by introducing micro calcium constituent, the cluster structure of disperse is formed in proof gold matrix, the structure can greatly improve the hardness and intensity of pure gold with the precipitation of the golden four titanium compounds hardening constituent of very effective promotion nanoscale.The pure gold so designed adapts to conventional processing technology of jewelry, can be used for various solid gold jewelries. |
