摘要：

Theoretical and experimental investigations of the solubility of gases dissolved in their plasma state in molten metals have shown that these solubilities are higher than the equilibrium solubilities attainable when the same gases are dissolved in their molecular state. Thermodynamic input-output balances for the dissolution and liberation of gases in molten metals, and calculation of the activation energies needed for these processes, yield guidelines for the design of equipment in which plasma torches will be able to supersaturate molten metals with gases at much lower pressures than are currently necessary.
