FIELD: process engineering.
SUBSTANCE: invention relates to machine building and can be used in repair and reconditioning of turbomachine blades. Proposed method comprises placing the part in sealed container, feeding chemical reagent therein and holding the part for time required for cleaning. Potassium fluoroborate (KBF4) is used as said chemical reagent. Note here that part and reagent are heated to at least 0.8T°m, where T°m is part material melting point. Reagent vapours act to the part while part surfaces are blown with argon.
EFFECT: efficient and accelerated cleaning.
