FIELD: blade repair technology.
SUBSTANCE: invention can be used in power engineering, aircraft engineering. The method for cleaning surfaces and microcracks in the blades of aircraft gas turbine engines and gas turbine units from metal oxides includes preparing a cleaning solution, cleaning in a steam chamber. The cleaning solution contains a mixture containing 8-12% by weight of phosphoric and 8-12% by weight of sulfuric acid, 76-84% by weight is water. Cleaning is carried out in a microwave steam chamber at a temperature of 230-250°C and a duration of at least 120 minutes, followed by rinsing with demineralized water in an ultrasonic bath.
EFFECT: cleaning surfaces and microcracks of blades of aircraft gas turbine engines and gas turbine units from aluminum, nickel, titanium, and chromium oxides.
