Sysoiev Y. Scientific basis of providing effective performance and control of ion-plasma processes in vacuum-arc technologies

Object of research - physical and technological processes in facility for of vacuum-arc coatings formation; purpose of research - development of methods and equipment for the formation of vacuum-arc coatings with high operational properties; research methods - plasma physics and discharge gas, thermal conductivity theory and heat transfer, solid state physics, molecular-kinetic gases theory analytical, numerical and experimental methods with use electron microscope "РЕМ-106", photomicroscope Neophot 30 ZEISS, ion-plasma unit "Bulat-6"; results - complex use of developed systems provides vacuum-arc coatings formation with high operational characteristics at simultaneously reduced resource cost; novelty - a number of methods were devised and on their basis next systems were developed: the obtaining of gases mixtures, high resource plasma sources at controlled temperature of the cathode working surface, decreasing the amount of microdrops in the plasma flow, elimination of microarc discharges, measuring the temperature of the products surface, producing coatings of equal thickness with a homogeneous composition, resource expenses reducing; implementation degree - method for obtaining gas mixtures with preliminary chamber mixer purging and gas mixtures generator that was implemented in NSC "KhPTI" (Kharkov), plasma sources combined ignition system and microarcs protection system was used in the enterprise "Zorya" "Mashproekt" (Nikolaev), as well as results of work was implemented in the educational process in the Zhukovsky National Aerospace University "KhAI"; industry - mechanical engineering.
