On the
Calculation of the Diffusion Coefficient of Oxygen in Zirconium Alloys by
Dissolution of the Oxide Film
Abstract
The
analytical expression for the oxygen mass, adsorbed in the isothermal
dissolution of the oxide film on the metall surface, is derived. This
expression is used to calculate the boundary reaction rate of oxygen atoms
transition from the oxid to the metall
and the oxygen diffusion coefficient at different temperatures for a-Zr-1%Nb
and b-Zr-20%Nb alloys by the proper treatment of experimental dates.
