    What are the characteristics of PVD coating?

    The PVD coating technology is applied to the film layer, which is characterized by high hardness, high wear resistance (low friction coefficient), good corrosion resistance, chemical stability and working long time. At the same time, the film layer can greatly improve the surface decoration performance of the workpiece. High hardness – hardness is an important performance index to measure the degree of compressive deformation of product materials. Let's look at a set of data: HV - Vickers Hardne... read more

    Can PVD coating replace chemical electroplating?

    At the present stage, PVD coating cannot replace chemical electroplating, PVD coating can be done directly on the surface of stainless steel materials, but many other materials (such as zinc alloy, copper, iron, etc.) should be electroplated by Cr(chromium) before PVD coating. PVD coating is mainly used for some high-grade hardware products. For those hardware products with low price, it is usually only used for electroplating instead of PVD coating.DLC Coating Machine Suppliers read more

    What are the advantages of PVD coating over traditional electroplating?

    PVD coating and traditional electroplating are similar, both belong to the category of surface treatment, both are to make a certain way to cover the surface of another material. The difference between the two is that PVD coating film layer and the surface of the workpiece have higher adhension, higher hardness of the film layer, better wear resistance and corrosion resistance, and more stable performance than electroplating. PVD coatings can be coated with a wider variety of films, can be plate... read more

  • What is PVD Coating?

    What is PVD Coating?

    PVD is the abbreviation of Physical Vapor Deposition . It refers to the practice of using low-voltage and high-current arc discharge technology to vaporize the target material and ionize both the evaporated material and gas under vacuum conditions. By using the acceleration of electric field, the evaporated material and its reaction products are deposited on the workpiece. PVD (physical vapor deposition) technology is mainly divided into three types: vacuum evaporation coating, vacuum sputtering... read more

    The development of optical coating machine technology in China

    The film layer is prepared in a vacuum, including plating a crystalline elemental or compound film such as a metal, a semiconductor, or an insulator. Although chemical vapor deposition also uses vacuum means such as reduced pressure, low pressure or plasma, vacuum coating generally refers to the physical deposition of a film. There are three forms of vacuum coating, namely evaporation coating, sputter coating and ion plating.Optical vacuum coating machine       Vacuum coating technology was firs... read more
