PVD (Physical Vapor Deposition) vacuum coating technology is a physical vapor deposition process, and its characteristics can be summarized from the following aspects:
1. Excellent film quality
High adhesion and durability: During PVD coating, ions bombard the surface of the workpiece at high speed, which can penetrate the surface of the workpiece and form a diffusion layer that is deeply injected into the substrate, so that the film layer and the substrate form a good bond and adhere firmly. The coating can plastically extend with the base metal without peeling or flaking, and can be bent more than 90 degrees without cracking or flaking.Dense and uniform structure: The PVD coating film is uniform and dense, without pinholes, bubbles, and uniform thickness. The edges and grooves can be evenly plated without forming metal nodules.
2. Excellent physical and chemical properties
High hardness and high wear resistance: PVD coating has extremely high hardness and wear resistance, and its low friction coefficient enables the coating to maintain excellent wear resistance in various environments.Good corrosion resistance and chemical stability: PVD coating can maintain the performance of anti-oxidation, non-fading, non-loss of gloss and non-marking under normal environment, including indoors and outdoors.
3. Strong decorative appearance
Diverse color selection: PVD vacuum coating can be plated with a variety of colors, such as IPG light gold, IP gold, IP furnace rose gold, IP coffee color, IP chrome, IP gray, brown, IP black, gun color, etc., which makes the product appearance more colorful and meets different aesthetic needs.Improve the decorative performance of the appearance of the workpiece: The uniform and dense film layer can greatly improve the decorative performance of the appearance of the workpiece.
4. Environmental protection and energy saving
Pollution-free: Compared with the traditional electroplating process, PVD coating technology does not produce toxic wastewater and exhaust gas, and is a pollution-free and environmentally friendly surface treatment method.Energy saving: During the coating process, the PVD coating process can make full use of evaporating substances, reduce energy waste, and achieve energy saving effects.
5. Wide application fields
PVD vacuum coating technology is widely used in automobiles, aerospace, electronics, optics, medical equipment, jewelry, watches, home decorations and other fields. In the automotive field, PVD coating can improve the hardness, corrosion resistance, wear resistance and scratch resistance of the body surface, and can also increase the gloss and aesthetics of the body. In the aerospace field, PVD coating is used for the protective film layer of the shell to resist extreme space environments such as solar radiation and micrometeoroid impact. In the electronics field, PVD coating is used to form conductive paths and insulating layers on circuit boards.
In summary, PVD vacuum coating technology has the characteristics of excellent film quality, excellent physical and chemical properties, strong decorative appearance, environmental protection and energy saving, and a wide range of applications. These characteristics make PVD vacuum coating technology have important application value and development prospects in modern industry.
