ИЗМЕЛЬЧЕНИЕ СТРУКТУРЫ ВНУТРЕННИХ ПОВЕРХНОСТЕЙ ОХЛАЖДАЕМЫХ ДЕТАЛЕЙ ГТД

Influence cobalt-aluminum surface modification on structure of the internal surfaces of the coolled gas-turbine engines details from nickel-base superalloy ЖС6У are studied in this art. Here designed fixing cobalt-aluminum substanse method on the ceramic pegs. It Is Installed that surface modification of internal surfaces of castings allows to get end-to-end pulverizing macrostructure, as well as improved microstructure.
