Abstract
:
A model for predicting oxidation rates of high melting-point metals in H2/H2O atmospheres is developed using thermodynamic equilibrium calculations and mass-transfer principles. From this model the erosion rate of high melting-point metals is calculated under oxidation condition controlled by the step of mass transfer through the boundary layer. This relatively simple model is shown to give reasonable agreement with reported experimental data for the rate of erosion of rhenium. Temperatures in the range from 2000 to 3000 K were used.
