METHOD OF ELECTROLYTIC-PLASMA POLISHING OF PARTS FROM TITANIUM ALLOYS

摘要

FIELD: electroplating.;SUBSTANCE: invention relates to electroplating and can be used in aircraft and power engineering, including during finishing of blades and other parts of GTE and GTI, as well as preparatory operation before ion-implantation modification of parts surface and application of protective ion-plasma coatings. Method involves immersion of part in electrolyte, formation around processed surface of part of vapor-gas shell and ignition of discharge between part and electrolyte by supplying to processed part of electric potential from 250 to 350 V at temperature of electrolyte 80–90 °C, wherein the part is preheated by immersing it in the heat carrier and holding in it for 1–2 minutes without supplying voltage, then the part is removed from the heat carrier, electric voltage is applied to it and once again the component is immersed into the electrolyte and polished for 0.8–2.5 minutes.;EFFECT: reduced power consumption for electrolytic-plasma polishing of parts from titanium alloys and processing time due to current stabilization and reduction of transient process.;3 cl, 2 dwg, 1 tbl
