Vacuum Systems for Deposition Hardening Coatings

Based on many years of experience of research and development works, as well as experience in manufacturing vacuum systems and the introduction of technology in of hardening industrial practice is the most appropriate use of the vacuum system with wide technological capabilities. Specifically, the system must include ion sources, vacuum arc and plasma magnetron sputtering systems. Such use of technological sources can clean the surface as gas ions and ions of the cathode material and to form single-layer, multi-layer, vacuum nanocomposite coatings, including the details of low annealing temperature (nitrides, carbides, carbonitrides, oxides and other compounds refractory materials).

The ion source in the vacuum system can be operate as a cleaning and in the mode of assisting, thus covering formed with high physical and mechanical properties. The presence in the vacuum systems system of the automatic flow control process gases allows to control cleaning of the surface details at the atomic level and provides management of key process parameters in automatic operation with the formation of coatings stoichiometric composition from cycle to cycle.
