Titanium coated principle

Titanium coated principle

  1. PVD coating

    PVD coating is physical vapor deposition. Stainless  steel coating, also called stainless steel titanium/zirconium coating,  forms a titanium/zirconium compound ion membrane layer on the surface of  stainless steel in a vacuum vessel, and the film can not fade in the  outdoor environment for many years.

  2. In high temperature, vacuum titanium furnace, titanium, zirconium metal, the  glow discharge of an inert gas is used to ionize the vapor of the metal  or alloy, and the ions are accelerated by the electric field to deposit  on the negatively-charged stainless steel plate, thereby forming a  metallic film with a rich and beautiful color and luster.

    PVD coating  is different from traditional electroplating methods, because of its  unique properties, high hardness, anti-abrasive, no peeling, no fading,  high corrosion resistance, and is not affected by ultraviolet rays.  Therefore, PVD-coated stainless steel is used as a unique decoration. Materials are widely used in various decorative areas.

    It also has the following properties: In the hot sun, it will not fade in the wet and general urban environment. Under ultraviolet light will not peel, do not peel off, do not fade. Various colors can be plated on various patterns and patterns.

  3. Coating color range and characteristics

    PVD coating color range of gold, brass, rose gold, silver white, black, bronze, copper, blue and so on.

    Surface features

    Appearance: pure metal film, dignified and gorgeous metallic luster.

    Corrosion and oxidation resistance: no fading, not easy to scratch.
    Versatility: The main surface decoration process inside and outside.
    Good plasticity: Above 90 degrees bending, it is not easy to break or peel and surface bruises.
    Resistance: The hardness coefficient exceeds 80RC.
    Durability: surface polishing can be maintained for more than 20 years
    Economicality:  Save (reduce) the time and expense of cleaning and polishing the  general copper (gold) plate. Use a soft cloth and glass cleaner.
    Anti-destructive: Handwriting and illustrations are easily eliminated.
    Environmental adaptability: Prevent the emission of harmful substances.

    Q1:What is PVD?

    A1:PVD is an acronym for Physical Vapor Deposition, meaning "Physical Vapor Deposition,"
    It  refers to a thin-film preparation technique that physically deposits a  material on a workpiece to be plated under vacuum conditions.

    Q2:What is PVD coating?

    A2:PVD  (physical vapor deposition) technology is mainly divided into three  categories, vacuum evaporation coating, vacuum sputtering coating and  vacuum ion plating.

    Q3: What is the specific principle of PVD coating?
    A3:  The principle of ion plating (PVD coating) technology is to use a  low-voltage, high-current arc discharge technique under vacuum  conditions. The gas discharge is used to evaporate the target and ionize  the evaporated substance. Under the action of the electric field, The evaporated substance or its reaction product is deposited on the workpiece.

  6. Q4: What are the advantages of PVD coating compared to traditional chemical plating (water plating)?
    1. The PVD coating is the same as the traditional chemical plating. Both  belong to the category of surface treatment, and they cover the surface  of another material in a certain way.

    2. The  difference between the two is that the PVD coating has a greater bond  with the surface of the workpiece, the hardness of the film is higher,  the wear resistance and corrosion resistance are better, and the  performance of the film is also more stable; the PVD coating can be  plated The type of film is more extensive, and the  colors of the various layers that can be plated are more and more  beautiful; the PVD coating does not produce toxic or contaminating substances.

    Q5: Can PVD coating replace chemical plating?

    At this stage, PVD coating cannot replace electroless plating, and in  addition to PVD coating directly on the surface of stainless steel, PVD  coating on many other materials (such as zinc alloy, copper, iron, etc.)  before PVD coating Both need to be electrolessly plated with Cr (chromium). PVD  coating is mainly used in some relatively high-grade hardware products.  For those hardware products with lower prices, it is usually only  electroless plating.PVD coating.

    Q6: What kind of substrate can PVD be plated on?

    PVD film  can be directly plated on stainless steel and hard alloy. For zinc  alloy, copper, iron and other die castings, electroplating of chromium  should be carried out before it is suitable for PVD plating.

    Q7: What are the types of film that PVD coating can plate?

    PVD coating technology is a kind of environment-friendly surface  treatment method that can truly obtain micron-scale coating without  pollution. It can prepare various single metal films (such as aluminum,  titanium, zirconium, chromium, etc.) and nitride films (TiN[ Titanium], ZrN [zirconium gold], CrN, TiAlN) and carbide films (TiC, TiCN), and oxide films (eg, TiO, etc.).

    Q8: What is the thickness of PVD coating?

    The  thickness of the PVD coating film layer is micron, the thickness is  thin, generally 0.1μm ~ 5μm, in which the thickness of the decorative  coating film layer is generally 0.1μm ~ 1μm, so the workpiece surface  can be improved without affecting the original size of the workpiece The  various physical properties and chemical properties, and can maintain  the basic size of the workpiece, after plating without further  processing.
