Introduction to Basic Knowledge of PVD Coating Machines
Release time:
2022-05-06
PVD coating machine technology is mainly divided into three categories: vacuum evaporation coating, vacuum sputtering coating, and vacuum ion plating. Comparing the three classifications of PVD coating machine technology, the corresponding vacuum coating equipment includes vacuum evaporation coating machines, vacuum sputtering coating machines, and vacuum ion plating machines.
PVD coating machine Introduction to Basic Knowledge
Detailed introduction to the five basic knowledge points of the PVD coating machine industry. If you want to enter or are preparing to enter the vacuum industry as a partner, you can refer to the following content:
1. PVD coating technology is mainly divided into three categories: vacuum evaporation coating, vacuum sputtering coating, and vacuum ion plating. Comparing the three classifications of PVD technology, the corresponding vacuum coating equipment includes vacuum evaporation coating machines, vacuum sputtering coating machines, and vacuum ion plating machines.
2. Vacuum arc ion plating machine (PVD coating technology, its principle is that under vacuum conditions, low-voltage, high-current arc discharge technology is used to evaporate the target material, and the evaporated material is ionized, so that the evaporated material or its reaction products are deposited on the workpiece under the action of an electric field. The similarity between PVD and traditional chemical plating is that both belong to the category of surface treatment, both covering the surface of one material with another material in a certain way. The difference is that: the bonding force between the PVD coating and the workpiece surface is stronger, the hardness is higher, the wear resistance and corrosion resistance are better, and the film performance is more stable; PVD can coat more kinds of films, and the colors of various films can be more beautiful. PVD coatings do not produce toxic or polluting substances.
3. PVD coating machines cannot yet replace chemical plating. In addition to PVD coatings being directly applicable to stainless steel surfaces, many other materials (such as zinc alloy, copper, iron, etc.) are also the case. )Chemical chromium plating is required before PVD coating. The thin film deposited by PVD coating technology has characteristics such as high hardness, high wear resistance (low friction coefficient), good corrosion resistance and chemical stability, and the service life of the thin film is longer. At the same time, the film layer can greatly improve the appearance and decorative performance of the workpiece.
4. PVD coating machines can be directly plated on stainless steel and cemented carbide. Die castings such as zinc alloy, copper, and iron should be chemically chromium-plated before being suitable for PVD electroplating. PVD coating technology is an environmentally friendly surface treatment method that can obtain pollution-free micrometer-level coatings.
The application of PVD coating technology can be divided into two categories: decorative coatings and tool coatings. The purpose of electroplating is mainly to improve the appearance, decorative performance and color of the workpiece, and at the same time make the workpiece more wear-resistant and corrosion-resistant, and extend its service life. This aspect is mainly applied to various fields of the hardware industry, such as door and window hardware, locks, sanitary ware hardware, etc.
PVD coating machine In addition to the above five basic knowledge points, there are also aspects such as optics, decoration, winding, and hard coating. According to the type. Different types have different relevant equipment knowledge.
