Abstract

The invention discloses a method for plating precious metal on a spherical surface. The method comprises the steps of etching a spherical surface carrier to form a spherical surface with a concave structure; spraying conductive ink onto the spherical surface with the concave structure, and drying to obtain a conductive spherical surface; adopting the conductive spherical surface as a cathode, andelectroplating in an electrolyte solution containing precious metal ions to obtain a precious metal-coated spherical surface; and polishing and turning the precious metal-coated spherical surface. According to the method, the precious metal and precious stone can be in seamless connection, so that people or clothes is prevented from being hurt; and meanwhile, the precious metal in the groove and the precious metal on the spherical surface form an integral structure so as to be prevented from falling off, and can form jewelry with alternant precious metal pattern and precious stone pattern.

Description

technical field [0001] The invention relates to the field of jewelry processing, in particular to a method for plating precious metals on a spherical surface. Background technique [0002] Jewelry refers to the raw materials and semi-finished products of jewelry, jade and precious metals, as well as the accessories, craft decorations and art collections made of raw materials and semi-finished products of jewelry, jade and precious metals, which not only have decorative functions, but also have extremely high collection value . With the improvement of people's living standards, people are not satisfied with a single gemstone or precious metal jewelry, but hope that precious metal jewelry can be placed in gemstones, such as Guanyin Buddha statues, flower and bird zodiac and other precious metal jewelry with beautiful meanings, thus giving gemstone jewelry more meaning. [0003] For common flat gemstones (jade, colored gemstones, diamonds), generally by being provided with gr...
