METHOD OF CLEANING SURFACE OF OBJECT (VERSIONS) Russian patent published in 1998 - IPC

FIELD: cleaning methods. SUBSTANCE: invention relates to plasma technology and can be applied when cleaning surface of conducting body. Method involves allowing discharge between object being treated and electrolyte by imposing positive potential on object with discharge current between object and electrolyte from 0.1 to 7.0 A and discharge voltage 20 to 500 V. According to the first version, object is positioned at a distance of 0-2 mm from electrolyte surface. According to the second version, object is immersed into electrolyte to a distance of 2.5-20 mm from the plate disposed on the bottom of electrolytic cell to give negative potential. EFFECT: increased cleaning area, both outside and inside. 2 cl, 4 dwg
