The color will be dropped for a long time. The gold -plated solution is scored according to the color. The rose gold is commonly used in gold and copper alloy with 85%gold. It has high wear resistance and chemical stability. It will also lose a little color. This kind of plating fluid is mainly composed of complexing agents, golden salt, and copper salt.
The gold -plated layer has good ductility, easy to polish, high temperature resistance, and has good resistance to color resistance. Gilling on the silver layer can prevent the discoloration of silver; the gold -alloy coating can present a variety of tones, so it is often used as a decorative plating layer, such as plating jewelry, watch parts, artworks, etc. Because gold prices are more expensive, mixed gold plating is generally used in gold plating. Will fade.
Extension information:
Gold plating standards:
The quality of gold plating quality is the thickness of the gold -plated layer, and the gloss is dark. At present, the standard gold plating jewelry standard is: good gold-plated jewelry plating thickness is 10 microns-25 microns, and general gold-plated jewelry plating thickness is 2 microns -3 microns. "Gold" is called "Gold".
It will fall off the color.
This gold -plated jewelry will be colored. Gilling refers to plating a layer of gold on the surface of other metal jewelry on the surface. The color is similar to the real gold jewelry. The golden light is bright, and it is difficult to identify when it is new. However, gold -plated jewelry feels lighter, the texture is hard, and the teeth bite the miles, and it is easy to fade after a long time.
The expansion information:
The gold -plated layer is golden yellow and has high chemical stability. It is only dissolved in the king water and other super strong acids, and insoluble in other acids. Gold's atomic price is one -price and three -valent. The standard potential φ ° AU /AU of one -price gold is 1.68V, and the standard potential φ ° AU3 /AU of the three -price gold is 1.50V. For steel, copper, silver, and its alloy matrix, the gold coating is a cathode coating, and the pores of the plating layer affect their protective performance.
The gold -plated layer has good ductility, easy to polish, high temperature resistance, and has good resistance to color resistance. Gilling on the silver layer can prevent the discoloration of silver; gold -alloy plating can present a variety of tones, so it is often used as decorative plating layers, such as plating jewelry, watch parts, artworks, etc.
Clating has low contact resistance, good conductive performance, easy to weld, strong corrosion resistance, and has a certain abrasion resistance (referring to hard gold), so in precision instrumentation, printed circuit boards, integrated circuits It has a wide range of applications, such as tube shell, electric connection point, etc.

After a long time, it will be faded.
The quality of gold plating quality is the size of the gold -plated layer, and the luster is dark and dark. At present, the standard gold plating jewelry standard is: good gold-plated jewelry plating thickness is 10 microns-25 microns, and general gold-plated jewelry plating thickness is 2 microns -3 microns. "Gold" is called "Tu Jin", which is a cheap jewelry technology.
Pucting data: Plating gold maintenance precautions
1. Avoid contact with hair gum, perfume, skin care products, contact with vinegar, bleaching agents, and other chemical components to deteriorate silver jewelry.
2, 925 silver has a high silver content, relatively soft, and avoid collision scraping and affect the texture.
3. If you want to make the newly bought silver jewelry more brighter and avoid its discoloration, there is also a trick, you can apply a thin layer of transparent nail polish on the surface of the silver jewelry. Apply once. If you want to remove nail polish, you can soak it with banana water, and then wash it with water.
4, the best maintenance method of silver jewelry is to wear every day, because human fats can make the silver a natural and warm luster.
5. When the silver oxidation is oxidized, it appears pale brown. It can be wiped with a little silver oil with a soft cloth, or soaked with silver water. Washing, wiping the stains generated as silver, can be used multiple times).

The production of electroplating gold jewelry is generally based on phosphorus and copper as the main material, forging at high temperature, and then covered with gold -plated layers. According to the different thickness of the gold layer, it is divided into two types: gold -plated and gold -packed gold. The thickness of the gold -plated gold layer is about 1 Mi (MIC (MIC) is the golden layer thickness unit), and the gold is about 3 mi.
If you do n’t pay attention to maintenance, you will have color loss and some other problems.
1. Do not wear gold plating bath, beauty, hair dyeing, soap, shampoo, etc. This is different from ordinary natural oxidation. If the plating gold ornament has the surface gold layer, it will show a dark black electroplating transition layer.
2. After wearing a soft cotton cloth every day, wipe the surface sweat and stains clean. If sweat more, clean it every day.
3. Silver jewelry containing 18K gold -plated and three -dimensional sculpture, you should avoid deliberately wipe the luster with silver cloth and cause fading.
4. Put back the sealed box or dedicated plastic bag every time after wearing it to avoid directly contacting the air to the air and cause the oxidation and discoloration. For the above, basically your gold -plated gold jewelry can be completely used for 5 years. Of course, it depends on your usage.
