EFFECT OF SILICON ON THE OXYGEN SOLUBILITY IN Ni – Co – Cr MELTS

https://doi.org/10.17073/0368-0797-2019-3-241-245

Abstract

 Thermodynamic analysis of the effect of silicon on the solubility of oxygen in Ni – Co – Cr melts has been carried out at 1873 K. Silicon at low contents practically does not affect the concentration of oxygen in Ni – Co – Cr melts, which is determined by the chromium content. With a higher content of silicon after changing the interaction mechanism of chromium and silicon with oxygen, when silicon already determines the solubility of oxygen in the melt, the oxygen concentration decreases. However, the deoxidizing ability of silicon at elevated contents in Ni – Co – Cr melts is much lower than in Ni – Co melts.
