In the surface treatment of badge production, the most common process is electroplating. The surface layers of the badge are mostly made of corrosive metals. The electroplating process can enhance the corrosion of the surface of the badge. A process of thin metals or other alloys on the metal surface.
In addition, the electroplating layer of the badge can also increase the smoothness of the badge, increase the hardness of the badge to prevent wear, and also improve the aesthetics.
Classification of electroplating process
The gold -plated badge is overall. The material is generally adopted by 18K gold and 24K gold. The surface effect has the effects of dumb gold and bright gold. The gold -plated medal has the characteristics of strong metallic sense, not easy to oxidize, bright color and long storage time.
There is also a gold -plated process that is plated, which is much lower than the cost of real gold. The color of imitation gold is close to real gold. The effect, the cost of imitation gold is relatively low, and at the same time, it can also improve the product and aesthetic.
Two: silver -plated
The silver plating process is placed on the metal surface of the badge on the metal of the badge, but in the current badge process, the silver -plated process has been used very little. This is mainly because the chemical properties of the silver are more active. It is easy to change color because of oxidation, and its color is not easy to maintain. Nickel is replaced in the process of making silver. The color of nickel is basically similar to the silver. The nickel chemical properties are stable. Nickel replaces the silver -plated process.
Three: copper plating
Copper is as easy to oxidize and loses as silver. The oxidized copper no longer conducts electricity. The copper material is under the action of carbon dioxide or chloride. Black or brown copper chloride will be generated. In the process of making bronze badges, it will generally add a layer of organic coverage to increase the attachment of electroplating.
The copper material that increases the coating will show pink, with good conductivity and easy to deal with the next step. In terms of appropriate chemical treatment, it will change color: copper green, bronze, and color, which is suitable for decoration for decoration Essence
Four: chrome -plated
Chromium hardness, good thermal resistance and abrasion resistance, good reflective ability, chromium is a silver -white or sky blue metal. Chrome -plated badges have excellent performance. Protective decoration.
Chromium can be preserved for a long time, and it will still be very stable in a variety of chemicals and corrosive medias. It is used as a badge to build materials. The preservation ability and length of use are better than nickel and silver.
Zinc, also known as zinc alloy, is the most commonly used high -quality raw material in badge manufacturing. Generally, the badge of collection value and long -time preservation is made of zinc alloy materials.
The badge made of zinc alloy material will generate a layer of passivation film on the surface under the combination of the air with oxygen, which can play a protective role. The zinc material can improve the decoration of the badge at the same time. Essence
