FIELD: medical engineering. SUBSTANCE: device has vacuum chamber, rotatable unit for placing articles, electric arc evaporator, gas supply system, discharge pumping system, power supply source and control unit. The evaporator is mounted at 45 deg to chamber bottom. Vacuum chamber size reduction and reduced distance from cathode to dental prosthesis under spraying allow supporting optimum dental prosthesis temperature at about 500 C while coating being done. EFFECT: improved quality and adhesion properties; uniform coating layer; simplified design; low power and water consumption; high performance characteristics. 6 cl, 1 dwg, 1 tbl
