1. what is PVD electroplating?
PVD is the abbreviation of Physical Vapor Deposition. It refers to the thin film preparation technology for depositing materials on coated parts under physical conditions.
2. What is the PVD coating? What is the PVD coating machine?
PVD (physical vapor deposition) technology is mainly divided into three categories: vacuum evaporation, vacuum sputtering and vacuum ion plating. Relative to the three classifications of PVD technology, the corresponding vacuum coating equipment also has vacuum evaporation coating machine, vacuum sputtering coating machine and vacuum ion plating machine.
3. what is the specific principle of PVD coating?
The principle of ion plating (PVD coating) is to use low voltage and high current arc discharge technology under the vacuum condition to vaporize the target and ionize the evaporated material by gas discharge. Under the action of the electric field, the evaporated substance or its reaction product is deposited on the workpiece.
4. what are the advantages of PVD coating compared with traditional chemical plating (water plating)?
PVD coating is the same as that of traditional chemical electroplating, both of which belong to the category of surface treatment, all of which cover the surface of another material by means of a certain way. The difference between the two is: the bonding force between the coating layer of PVD and the surface of the workpiece is greater, the hardness of the coating is higher, the wear resistance is better and the performance of the film is more stable; the type of coating of the PVD coating can be more widely, and the color of the coating can be more, and the color of the pigment is especially strong and very beautiful. What's more, PVD coating does not produce toxic or polluting substances.
5. what color can PVD coating have?
gold; 2.light gold; 3.zirconium gold; 4.champagne gold; 5.rose gold; 6.copper; 7.coffee color; 8. silver
