FIELD: technological processes.
SUBSTANCE: invention relates to electrolytic-plasma polishing of parts made of refractory alloys, and can also be used in turbomachinery for the processing of blades of steam turbines, blades of gas pumping units and gas turbine engine compressors. Electrolyte for electrolytic-plasma polishing of parts made of refractory alloys contains an aqueous solution of hydroxylamine hydrochloric acid and sodium fluoride, at the following ratio of components, g/l: hydroxylamine hydrochloric acid NH2OH×HCl – 24 to 40; sodium fluoride NaF – 9 to 22.
EFFECT: expansion of technological capabilities of the electrolyte due to the provision of polishing of parts made of titanium alloys and heat-resistant alloy EP741NP.
