Silica-free binder ALUMOX is tested under conditions of the AO NPTs Gas Turbine Construction Salyut casting shop conditions. Amethod is developed for preparing composite ceramic molds for investment casting of critical superalloy components by directional solidification. Use of these molds makes it possible to prepare castings by high-gradient directional solidification answering component drawing specifications and technical conditions. The protective layer of the composite mold based on ALUMOX binder significantly reduces chemical interaction of the mold working layer with components of superalloy ZhS26-VI during pouring and cooling compared with the degree of interaction of a standard mold based on ÉTS-40 binder.
