METHOD OF PULSE-PERIODIC ION TREATMENT OF METAL WARE, AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2012 - IPC C23C14/48 

FIELD: metallurgy.

SUBSTANCE: method involves arrangement of metal ware in vacuum chamber, cleaning of surface of the ware by bombardment with ions and electrons, supply of ionised substance, its ionisation for formation of ion plasma and acceleration of ions in plasma with electric field. At that, plasma generation and acceleration of ions is performed in turn and for many times. Device used for implementation of the method includes earthed metal vacuum chamber with external electrode and reference electrode fixed in it and connected to voltage source. Voltage source is connected through control unit to the first commutator connected to the first high-voltage capacitive storage which is connected to middle point of secondary winding of high-voltage pulse transformer and to the second commutator. At that, the second commutator is connected to the second high-voltage capacitance storage connected to primary winding of high-voltage pulse transformer.

EFFECT: improving operating properties of ware surfaces; enlarging the period of their wear resistance.
