Vacuum coating machine coating related knowledge questions and answers

First: Is the cost of vacuum coating machine coating very high?
Although PVD coating technology can be used to plate high-quality films, the cost of PVD coating process is actually not high. It is a very cost-effective surface treatment method, so PVD coating technology has developed very fast in recent years. PVD coating has become the development direction of surface treatment in the hardware industry. PVD is the abbreviation of Physical Vapor Deposition (Physical Vapor Deposition), which refers to the use of low-voltage, high-current arc discharge technology under vacuum conditions to use gas discharge to evaporate the target material and ionize the evaporated material and gas. Using the acceleration of the electric field, the evaporated substance and its reaction product are deposited on the workpiece. NCVM=Non-Conductive Vacuum Metallization: Literally translated as non-conductive vacuum plating (metal surfaceization), process: non-conductive coating. In fact, PVD mainly uses the perspective of physical and chemical comparison, while NCVM focuses on the effect produced after coating Expressed. In fact, the two are the same.

Second: What industries are the current vacuum coating machine coating technology mainly used in?
The application of PVD coating technology is mainly divided into two categories: decorative plating and tool plating. The purpose of decorative plating is mainly to improve the appearance, decorative performance and color of the workpiece while making the workpiece more wear-resistant and corrosion-resistant to prolong its service life; this aspect is mainly used in various fields of the hardware industry, such as door and window hardware, locks, bathroom hardware and other industries. The purpose of tool plating is mainly to improve the surface hardness and wear resistance of the workpiece, reduce the friction coefficient of the surface, and improve the service life of the workpiece; this aspect is mainly used in various knives, scissors, turning tools (such as turning tools, planers, milling , drill bits, etc.) and other products.

Third: What is the thickness of the coating layer of the vacuum coating machine?
The thickness of the PVD coating film layer is micron-level, and the thickness is relatively thin, generally 0.1 μm to 5 μm. The thickness of the decorative coating film layer is generally 0.1 μm to 1 μm, so the surface of the workpiece can be improved without affecting the original size of the workpiece. Various physical and chemical properties, and can maintain the size of the workpiece basically unchanged, no further processing is required after plating.

Fourth: What are the types of films that the vacuum coating machine can coat?
PVD coating technology is an environmentally friendly surface treatment method that can truly obtain micron-scale coatings without pollution. It can prepare various single metal films (such as aluminum, titanium, zirconium, chromium, etc.), nitride films (TiN [titanium gold ], ZrN [zirconium gold], CrN, TiAlN) and carbide films (TiC, TiCN), and oxide films (such as TiO, etc.).

Fifth: May I ask what are the characteristics of the film layer coated by vacuum coating machine coating technology?
The film layer plated by PVD coating technology has the characteristics of high hardness, high wear resistance (low friction coefficient), good corrosion resistance and chemical stability, etc., and the life of the film layer is longer; at the same time, the film layer can be greatly Improve the appearance and decoration performance of the workpiece.
