    PVD (Physical Vapor Deposition) refers to vacuum coatings methods to produce thin films and is divided into two general methods

    1-evaporatio

    2-sputtering

    Each of the mentioned methods can be done with several different models


    One of the most widely used models of evaporation method is cathodic arc evaporation(Arc-PVD)method. This method can be done in DC or AC modes. In each mode, the voltage generated by the power supply causes an electric arc between anode and cathode. The arc current is concentrated on a very small surface of the cathode(target) and produces a very high current density that causes the cathode to evaporate and turn into ionized vapor. Ionized vapor reacts with inlet gases into the chamber (oxygen, nitrogen, etc.) and precipitates as a thin ceramic layer on the surface of pieces. Various types of metals, ceramics and heat-resistant compact plastics such as ABS can be coated using the Arc-PVD method. Due to the creation of very desirable properties, this method can be used to create decorative coatings as well as hard industrial coatings

    PVD Decorative coatings are created layers with various colors and high durability on all kinds of sanitary faucets & accessories, Ceramic & mosaic tiles, Kitchen appliances, car rings, Door and window handles, etc., which,while being beautiful and durable, have anti-scratch, anti-acid and very high hardness properties

    Due to its wear resistant, corrosion resistant, high hardness and thermal stability properties, Arc-PVD is used in various industries to create hard coatings on a variety of cutting tools, industrial molds, etc
