Originální abstrakt

The interaction of ceramic alumina-mullite mould with nickel and nickel alloys (ZhS6K, NiTi and NiCr) was studied at a temperature of 1773K in the pressure range from 0.1 Pa to 1 atm. The ceramic mould contained a continuous network of pores, which provided for the releasing of the gaseous phase at the mould/metal interface and thus facilitated physical and chemical erosion of the face layer of the mould at low pressures. Increasing the pressure of gaseous atmosphere to over 0.1 atm practically prevented the erosion of mould surface by nickel and its alloys.
