1 Revolution in physical vapor deposition BY MEAN OF PLASMA ARC ACCELERATOR

2 Technology Highlights  Coating of heat labile materials  Effective operation in the residual gas atmosphere and reactive gases (nitrogen, oxygen) environment  Coatings with specified properties  Several different materials can be deposited simultaneously or in controlled sequence  Synthesis of the non-transferable material on the surface  Multilayer films can be grown  Roll-to-Roll modification of linear model  Different types of consumables  Operation without micro-drop fraction  Substrate control and transfer of composition  Transfer of electrophysical properties  Substrate zone plasma beam focusing  Permanent “activation” of the substrate by helicon source

3 Technology Highlights  Known vacuum coating technology, such as thermal, electron-beam, vacuum-arc evaporators and magnetron sputtering systems, cause fractionation of consumable materials and ensure the preservation of its composition in the deposited film. In case this is due to the evaporators Time of Flight effects for components with different masses, and for the magnetron systems - due to the effect of selective spraying at which light components from the target sprayed with greater speed.  Technology from GreSem is performed using a specially designed magnetically activated vacuum-arc source as the generator of the accelerated plasma flow of multi-component coating film and helicon plasma source for surface preparation and its activation during the coating process.
