FIELD: metallurgy.
SUBSTANCE: invention can be used to repair and strengthen wind turbine blades of aircraft gas turbine engines with working temperature at least 1000°C. The cobalt based alloy contains, wt %: chromium 22-27, tungsten 7-10, nickel 5-12, carbon 1-1.8, silicon 0.1-1, titanium 1-2, at least one rare earth metal from the group comprising cerium, lanthanum and yttrium, 0.01-0.2; zirconium or hafnium, 1-2; the rest is cobalt.
EFFECT: alloy is characterized by high working temperature, low friction coefficient, low wear rate and linear wear at working temperatures.
