FIELD: metallurgy. ^ SUBSTANCE: invention relates to surface treatment of metals, particularly it relates to facilities for treatment of details in non-self-maintained glow discharge and can be used in mechanical engineering, automobile and armature engineering. Facility contains vacuum chamber, padding for location of details, power supply, connected to negative contact with padding, by positive - with chamber's body, thermoemission electrode, the second power supply, connected to negative contact with thermoemission electrode, by positive - with chamber's body. Facility also contains additional cored cylindrical electrode and additional regulated direct voltage source. Internal diametre of additional electrode increases geometry of treated detail and provides angle of sight of ion flux on the surface of treated detail from zero up to critical. Herewith additional electrode is co-axial located between thermoemission electrode and treated detail. Additional regulated direct voltage source by negative contact is connected to padding, and by positive - with additional electrode. ^ EFFECT: increasing of details' endurance limit and power inputs decreasing. ^ 1 dwg |
