Thermodynamic Modeling of Ni-Si-Cr-B-C System in Air and Propane Atmosphere
Thermodynamic modeling of a powder self-fluxing material PGSR-2 based on nickel (wt. %): Ni-79.3, C-0.5, Cr-15, Si-3.2, B-2 was carried out. Modeling was executed in the temperature range of 300-6000 K in the atmosphere of air and gas mixture “92 vol. % air + 8 vol. % propane” at a total pressure of...

| Résumé: | Thermodynamic modeling of a powder self-fluxing material PGSR-2 based on nickel (wt. %): Ni-79.3, C-0.5, Cr-15, Si-3.2, B-2 was carried out. Modeling was executed in the temperature range of 300-6000 K in the atmosphere of air and gas mixture “92 vol. % air + 8 vol. % propane” at a total pressure of P=105 Pa. The temperature dependences of the equilibrium composition of the condensed and gas phases formed during the heating of the investigated system were calculated. It is shown that the distribution of the components of the condensed and gas phases changes significantly when the initial content of the powder material and the composition of the plasma-forming gas are changed. |
