A technology of inlaying silver ornaments on ceramic workpieces

Abstract

A technology for inlaying a silver ornament on a ceramic workpiece comprises the steps of firstly processing an inlaying hole in the surface of the ceramic workpiece, processing a connection column, matched with the inlaying hole, on the silver ornament, and putting the connection column of the silver ornament into the inlaying hole, so as to combine the silver ornament with the ceramic workpiece, wherein the operation of processing the inlaying hole in the ceramic workpiece comprises the steps of firstly performing metallization pretreatment on the surface of the ceramic workpiece, then processing the inlaying hole, and bonding a layer of silver connection matrix on the inner wall of the inlaying hole; the operation of combining the silver ornament with the ceramic workpiece comprises the steps of evenly spreading a layer of borax on the outer surface of the connection column and the inner wall of the inlaying hole, then putting the connection column of the silver ornament into the center of the inlaying hole, filling a gap between the connection column and the inlaying hole with silver solder until the silver ornament is no longer loosened, and finally brazing in an electric furnace in a reducing or inert atmosphere, so that the silver ornament and the ceramic workpiece are tightly combined into a whole. By adopting the technology, the silver ornament and the ceramic workpiece are tightly combined into the whole with high combining strength, and the technology is concise and suitable for popularization and application.

Description

technical field [0001] The invention relates to the field of ceramic processing, in particular to a technique for inlaying silver ornaments on ceramic workpieces. Background technique [0002] China is the birthplace of ceramics, and the collection of ceramics is the favorite of many Chinese people. In the production process of the ceramics industry today, gold or silver painting is mainly carried out on ceramic blanks, and then after roasting and firing, what is obtained is a single The color pattern of this kind of combination of ceramics and precious metals is a relatively common production process in the ceramic industry. In the firing process, the oxidation is serious, it is not wear-resistant, and the combination of ceramics and gold or silver is very weak. In 2014, the State Intellectual Property Office published an invention patent titled a manufacturing process of anti-scalding ceramic silverware, and the patent number is 201410194326.2.

[0002] China is the birthplace of ceramics, and the collection of ceramics is the favorite of many Chinese people. In the production process of the ceramics industry today, gold or silver painting is mainly carried out on ceramic blanks, and then after roasting and firing, what is obtained is a single The color pattern of this kind of combination of ceramics and precious metals is a relatively common production process in the ceramic industry. In the firing process, the oxidation is serious, not resistant to wear, and the combination of ceramics and gold or silver is very weak

In 2014, the State Intellectual Property Office published an invention patent titled a manufacturing process of anti-scalding ceramic silverware, and the patent number is 201410194326.2. This patent discloses a process for inlaying silverware on the inner surface of ceramic vessels. The process proposes to carve grooves on the surface of the inner cavity of the ceramic vessel first, then mold the silverware into a liner that matches the shape and size of the groove in the mold, and finally put the silver liner into the groove through mechanical pressure to make the ceramic and silverware Form a mechanical combination. The combination method proposed by this process is a simple mechanical combination of ceramics and silver. The combination method is single and not stable, and the process requires manual calculation of dimensions and mechanical grinding, which is time-consuming and laborious.

The manufacturing process of this new type of handicraft is relatively complicated and special, and the most critical part is the combination of ceramics and metal parts. In the prior art, there are many combination processes of ceramics and metals, such as metallization of ceramics, surface of ceramic workpieces, etc. The gold-plated and silver-plated treatment, these bonding methods are simply covering a layer of metal bonding layer on the surface of the ceramic, which is not a combination of ceramics and complete metal parts in essence. The patent No. 201110242568.0 published in 2011 is an invention patent. It is "a welding method for welding ceramics and aluminum using the superposition method". The patent proposes that the surfaces of ceramics and aluminum are firstly combined with various metal transition layers, and then ceramics and aluminum are welded through the metal transition layer on the surface. This welding method is only suitable for ceramic plates for industrial use, and the welding area is large and the cost is high, so it is not suitable for small ceramic workpieces. For this reason, a new type of handicraft that combines ceramic workpieces with precious metal ornaments, especially silver ornaments, needs a unique and Effective process for bonding silver jewelry to ceramic workpieces
