Introduction to the basic knowledge of PVD coating machine coating
Release time:
2022-03-28
Films deposited using PVD coating machine technology are characterized by high hardness, high wear resistance (low friction coefficient), good corrosion resistance and chemical stability, and a longer service life. At the same time, the film layer can greatly improve the appearance and decorative performance of the workpiece.
Introduction below PVD coating machine Five basic knowledge points in the coating 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 machine technology is mainly divided into three categories: vacuum evaporation coating, vacuum sputtering coating, and vacuum ion plating.
2. PVD coating machine technology, its principle is under vacuum conditions, using low-voltage, high-current arc discharge technology, through gas discharge to evaporate the target material, and make the evaporated material ionized, the evaporated material or its reaction products are deposited on the workpiece under the action of the electric field.
3. The films deposited by PVD coating machine technology have high hardness, high wear resistance (low friction coefficient), good corrosion resistance and chemical stability, and longer service life. 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. Zinc alloy, copper, iron and other die castings should be chemically chromium-plated before PVD coating. It can prepare various single metal films (such as aluminum, titanium, zirconium, chromium, etc.), nitride films (TiN [titanium gold], ZrN [zirconium gold], CrN, TiAlN), carbide films (TiC, TiCN) and oxide films (such as TiO, etc.). The thickness of PVD coating is in micrometers, which is relatively thin, generally 0.1 μm ~ 5 μm, among which the thickness of decorative coating is generally 0.1 μm ~ 1 μm, so it can improve various physical and chemical properties of the workpiece surface without almost affecting the original size of the workpiece, and can keep the workpiece size basically unchanged.
Not only the above PVD coating machine Basic knowledge, such as optical, decorative, winding, hard coating, etc. Depending on the type, the relevant equipment knowledge is also different.
