Vacuum Technology sets the Standards for Improving Quality of Products
Posted by ivtcoltd on September 18th, 2014
The significance of vacuum technology is felt in every industry where the need for physical measurement and processes are performed in a vacuum to achieve a particular desirable state. It would not have been feasible under normal atmospheric conditions since a vacuum state can help in melting of reactive metals, help in freeze-dying or degassing of oils, reduce number of molecular impacts every second and so on. IVT Co., Ltd. a well-known precision turned parts manufacturer in Korea aims at producing excellent vacuum products with absolute fulfillment of promises. Here, we provide you an insight of how physical vapour deposition (PVD) processes are carried out in vacuum conditions.
Application of PVD technology
PVD coating finds a great array of applications in fields like aerospace, surgical or medical field, automotive, cutting tools, fire arms, dies and moulds, and so on. Physical vapour deposition equipment helps in transfer of material on atomic level. There are four separate steps as followed under this process, which include: evaporation, transportation, reaction and deposition.
Evaporation- Described as the first stage, it involves materials that need to be deposited. These materials are bombarded by high energy source like ions or electrons and get vaporized.
Transport- The process involves movement of vaporised atoms from the particular target to the substrate in a straight line affair.
Reaction- During the transport stage, the atoms of metals will react with appropriate gas. In this case, the reactive gases may be nitrogen, oxygen and methane.
Deposition- This is the last stage where coating build up is formed on the substrate surface.
PVD coatings are used for improving hardness and also wear resistance. By minimizing friction and improving oxidation resistance, PVD coating helps to boost performance. Physical vapour deposition equipment follows the above string of methods to ensure coating of components most diligently, so as to improve properties and accelerate performance of coated components. In contrast to the method of electroplating, PVD coating is more environmental friendly.
Yet again, magnetron sputtering is another significant form of PVD coating technology.
What is Magnetron Sputtering Technology?
It is described as a plasma coating process in which sputtering materials are ejected to the target surface due to bombardment of ions. The inside chamber of magnetron sputtering equipment is filled with inert gas that helps in acceleration of ions that target plasma coating on the surface. The sputtering materials as ejected enable in creating layers of coating on products, which are placed in front of the target. Notably, magnetron sputtering technology involves usage of magnetic fields to intensify bombardment of ions for producing highly dense plasma.
The technology is characterized by the following:
