DEVICE FOR ELECTRON BEAM DEPOSITION COATING BASED ON POLYMERS IN VACUUM
Purpose
Thin polymeric films of micron and submicron thickness are of great interest for modern technologies of instrument engineering, electrical equipment, fine mechanics and other sectors of industry. It is caused by favorable and even unique combination of properties in polymer materials: high chemical resistance, good dielectric characteristics, hydrophobicity, low coefficient of friction, elasticity and other factors. E-beam dispersion device is applied to form polymeric coatings in vacuum.
Description and technical characteristics
Device for electron beam deposition polymer coating structurally consists of: − power unit; − еlectron beam projector. Electron beam projector and a power unit allow forming the stream of electrons with energy and current density, sufficient to transfer the target material into the active gas phase.
Power unit
Power unit (PU) of the device of e-beam dispersion is used to supply the accelerating voltage and filament current in the electron beam evaporator (EBE) of vacuum assembly. EBE together with PU are used to evaporate in vacuum of technological materials with the subsequent sedimentation on the parts. The power block and a set of connecting cables are included in the package.
Electron beam projector
The electron beam projector with the cathode of direct heating allows to form bunches of electrons with a density of current I = 50÷500 A/sq.m, energy of particles E = 0,1÷2,5 keV, the area of the spot S = (1÷5)•10-4 sq.m. The range of energy of electrons E = 0,8 … 2,0 keV, used while dispersing organic and inorganic compounds, is optimum. The control of the device is also realized through management elements located on the forward console of the device.
