Sažetak
An analytical review of the existing views on the problem of the high-temperature strength of high-temperature nickel alloys of the of gas turbine engine blades has been carried out.. For the treatment of nickel melts, a complex powder modifi er based on titanium carbonitride Ti (CN) with a particle size of 50...100 nm was proposed. An increase of the alloys mechanical properties of alloys was also achieved: Rv0, 2 – by 10… 13 % ; Rm – by20% ; KCU - by 40%. The tests for high-temperature corrosion showed decrease of the corrosion depth in modified samples by 25%, which is confi rmed by the effect of modifying with nanodispersed modifi ers.
