FIELD: engines and pumps.
SUBSTANCE: determine the lines for cutting the platforms for repair. Remove the defective parts along the said line. Fabricate the hard-alloy material plates of thickness not more than 0.9 mm with through slots along the contour, coinciding with the planes of the platform repair cut. Fix them on the cut planes with the requirement to maintain the specified length of the platforms, perform heat treatment and final finishing machining. In this case, after removal of the defective parts of the platforms along the specified line of the repair section, a layer of titanium alloy of a given thickness is cladded onto the repair section, and then the plates are fixed using the induction soldering.
EFFECT: method will increase reliability of the product during its operation, increase service life of the blades in 1,5-2 times.
