Use of Low-Active Circulating-Gas Aluminizing for Repairing the Nozzle-Set Containers of a Turbine

Metal Science and Heat Treatment Aims and scope

Abstract

The cause of damage in internal and external containers of the nozzle set of the first stage of the TV3-117 engine is shown to be the intercrystallite gas corrosion of the materials of which they are produced (alloy KhN38VT and steel 12Kh18N10T, respectively). It is shown that low-active circulating-gas aluminizing can be used for repairing the parts, increasing their high-temperature strength, and “curing” micro- and macrocracks.
