Specific embodiment
For the ease of understanding the present invention, the present invention will be described more fully below.But the present invention can be with perhaps
Mostly different form is realized, however it is not limited to embodiment described herein.On the contrary, the purpose for providing these embodiments is to make
To the understanding more thorough and comprehensive of the disclosure.
Unless otherwise defined, all of technologies and scientific terms used here by the article is with belonging to technical field of the invention
The normally understood meaning of technical staff is identical.Term used in the description of the invention herein is intended merely to description tool
The purpose of the embodiment of body, it is not intended that in the limitation present invention.
The present invention provides a kind of high tenacity gold article fabrication methods, for processing golden product, especially gold jewelry for example
Gold bracelet improves the toughness of gold ornaments, prevents to be cracked, and extends the service life of jewellery.
In a wherein embodiment, gold bracelet semi-finished product for the gold bracelet half after being processed early period into the present invention one compared with
The high tenacity gold article fabrication methods of good embodiment, include the following steps.
First, it is 95%-99%'s to provide the first acid solution containing sulfate ion, concentration that concentration is 95%-99%
The second acid solution containing nitrate ion and gold bracelet semi-finished product.
2nd, by the first acid solution and the second acid solution with volume ratio 8.5-9:1-1.5 is mixed, and it is molten to form pickling
Liquid；
3rd, pickling solution is heated up to 70 DEG C -90 DEG C, gold bracelet semi-finished product is placed in pickling solution and soak 2-5s, so
After take out；
