Electroplating process

The electroplating process is a method of coating a conductor with a layer of metal using the principle of electrolysis. Electroplating refers to a surface processing method in which the base metal to be plated is used as the cathode in a salt solution containing pre-plated metal, and the cations of the pre-plated metal in the plating solution are deposited on the surface of the base metal through electrolysis to form a coating. .
The properties of the coating are different from those of the base metal and have new characteristics. According to the function of the coating, it is divided into protective coating, decorative coating and other functional coating.
During electroplating, the plated metal or other insoluble material is used as the anode, the workpiece to be plated is used as the cathode, and the cations of the plated metal are reduced on the surface of the workpiece to be plated to form a plated layer. It can enhance the corrosion resistance of metal (the coating metal is mostly corrosion-resistant metal), increase hardness, prevent wear, improve conductivity, smoothness, heat resistance and surface beauty. Electroplating is an electrochemical process as well as a redox process.
The basic process of electroplating is to immerse the part in a solution of metal salt as the cathode, the metal plate as the anode, and after connecting the DC power supply, deposit the desired coating on the part. For example, when nickel plating, the cathode is the part to be plated, and the anode is a pure nickel plate. The following reactions occur at the cathode and anode respectively:
Cathode (plated part): Ni2++2e→Ni (main reaction)
2H++2e→H2↑ (side reaction)
Anode (nickel plate): Ni-2e→Ni2+ (main reaction)
4OH--4e→2H2O+O2 (side reaction)
Not all metal ions can be deposited from the aqueous solution. If the side reaction of the reduction of hydrogen ions to hydrogen on the cathode is dominant, the metal ions are difficult to precipitate on the cathode. According to experiments, the possibility of electrodeposition of metal ions from aqueous solutions , which can be obtained from the periodic table of elements.
Anodes are divided into soluble anodes and insoluble anodes. Most anodes are soluble anodes corresponding to the coating, such as zinc anodes for zinc plating, silver anodes for silver plating, and tin-lead alloy anodes for tin-lead alloy plating, but a few electroplating Due to the difficulty in dissolving the anode, insoluble anodes are used. For example, acid gold plating uses platinum or titanium anodes. The main salt ions of the plating solution are supplemented by adding a prepared standard gold-containing solution. The chromium plating anode uses pure lead and lead-tin alloy. Insoluble anodes such as lead-antimony alloys.
The electroplating process of the brake disc is equivalent to integrating the golden yellow paint into the brake disc material, and the electroplating treatment will penetrate into every corner of the brake disc. The electroplated brake discs are not only beautiful but also rust-free. There will be a dazzling golden light in the sunlight. Moreover, the price of the electroplating treatment process is also very close to the people. Those who love car modification can consider starting it.
