Advanced technological developments for casting GTE blades of aircraft and power engineering application

The alloy surface modification during the blade casting by introducing the firstly synthesized in VIAM cobalt aluminate into the ceramic shell resides in the fact, that the artificial nuclei are generated on the casting shell surface during the casting process of metal solidification. Hence, the definite corrective amendments are put into the solidification process kinetics, ensuring in this case the density increase, liquation heterogeneity decrease macrograin and the refinement of casting metal microstructure fragments. The significant improvement and stabilization of basic alloy characteristics, firstly, endurance and heat resistance limits, allow to increase a blade reliability of AL-21F, AL-31F, RD-33 and other engines as well as to improve their service life by 3-5 times. The alloy surface modification is widely used in the engine-building industry. VIAM produces and delivers cobalt aluminate with the predetermined chemical and granulometric composition according to the required volumes.
