500万彩票PVD is the abbreviation of physical vapor deposition in English, which means "physical vapor deposition" in Chinese. It refers to the thin film preparation technology that makes materials deposited on the plated workpiece by physical method under vacuum condition.
500万彩票PVD coating and PVD coating machine
PVD (physical vapor deposition) coating technology can be divided into three categories: vacuum evaporation coating, vacuum sputtering coating and vacuum ion coating. Corresponding to the three categories of PVD technology, the corresponding vacuum coating equipment also has three kinds of vacuum evaporation coating machine, vacuum sputtering coating machine and vacuum ion coating machine. In recent ten years, the development of vacuum ion plating technology is the fastest, it has become one of the most advanced surface treatment methods. PVD coating refers to vacuum ion coating; PVD coating machine refers to vacuum ion coating.
PVD coating (ion coating) technology, the specific principle of which is to use the arc discharge technology of low voltage and high current under the vacuum condition, use the gas discharge to make the target evaporate and ionize the evaporated substance and gas, and use the acceleration of electric field to make the evaporated substance and its reaction products deposit on the workpiece.
The characteristics of PVD coating, the coating by PVD coating technology, has the characteristics of high hardness, high wear resistance (low friction coefficient), good corrosion resistance and chemical stability, and the service life of the coating is longer; at the same time, the coating can greatly improve the appearance and decoration performance of the workpiece.
500万彩票PVD coating technology is a kind of environmental protection surface treatment method that can truly obtain micron level coating and no pollution. It can prepare various single metal films (such as aluminum, titanium, zirconium, chromium, etc.), nitride films (tin, ZrN, CrN, TiAlN), carbide films (TIC, TiCN), and oxide films (such as TiO, etc.). Thickness of PVD coating - the thickness of PVD coating is micrometer level, which is relatively thin, generally 0.3 μ m ~ 5 μ m, among which the thickness of decorative coating is generally 0.3 μ m ~ 1 μ m, so it can improve the physical and chemical properties of the workpiece surface without affecting the original size of the workpiece, and it does not need to be processed after plating.
500万彩票The color types of the film that can be plated by PVD coating - the color of the film that can be made by PVD coating at present includes dark golden yellow, light golden yellow, coffee color, bronze color, gray, black, gray black, seven colors, etc. By controlling the relevant parameters in the process of coating, the color can be controlled; after coating, the color can be measured with relevant instruments, so that the color can be quantified to determine whether the color can meet the requirements.
The similarities and differences between PVD coating and traditional chemical plating (water plating) PVD coating and traditional chemical plating have the same points: both belong to the category of surface treatment, which make one material cover the surface of another material in a certain way. The differences between the two are: the adhesion between PVD coating and workpiece surface is greater, the hardness of the coating is higher, the wear resistance and corrosion resistance are better, and the performance of the coating is more stable; PVD coating will not produce toxic or polluting substances.
500万彩票At present, PVD coating technology is mainly used in the industry. The application of PVD coating technology is mainly divided into two categories: decorative coating and tool coating. The purpose of decorative plating is mainly to improve the appearance, decoration performance and color of the workpiece and make the workpiece more wear-resistant and corrosion-resistant to extend its service life; in this respect, it is mainly used in various fields of 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 cutting tools, turning tools (such as turning tools, planers, milling cutters, drills, etc.), various hardware tools (such as screwdrivers, pliers, etc.), various molds and other products. :

The main characteristics and advantages of PVD (ion plating) technology - compared with vacuum evaporation coating and vacuum sputtering coating, PVD ion plating has the following advantages:
500万彩票A. the binding force between the film layer and the workpiece surface is strong, more durable and wear-resistant
500万彩票B. the ion diffraction performance is good, and the workpiece with complex shape can be plated with 0V + r0s4
C. fast film deposition rate and high production efficiency
D. wide range of coating types
500万彩票E. the film has stable performance and high safety (it is FDA certified and can be implanted into human body)
