Abstract

Corundum forms with polystyrene models were used to produce parts of the gas-turbine plants. Polystyrene models and products of destruction from forms were removed by the two-stage burn method. Optimal temperature and time parameters of this process are presented. It is shown that the developed technology allows to obtain high-quality castings from ЧС 104 heat-resistant alloy and 18X2H4MA steel without surface and volumetric carburizing.
