Oxidation kinetics of zirconium nitride. I. Planar symmetry
Description
The oxidation behavior of ZrNsub(0.93) plates was investigated at temperatures in the range 625-800 deg C in oxygen over the pressure range 10-730 torr. The reaction product consists of monoclinic zirconia accompanied with trace amounts of cubic or tetragonal zirconia. Although the kinetic results are well interpreted by a Prout and Tompkins type model. The morphological observations suggest a transformation governed by a phase boundary reaction, this being confirmed by the oxygen pressure dependence on the rate law
Abstract (French)
On etudie le comportement de plaquettes de nitrure de zirconium ZrNsub(0,93) traitees entre 625 et 800 deg C sous une pression d'oxygene comprise entre 10 et 730 torr. La reaction d'oxydation conduit a la formation de zircone monoclinique accompagnee de zircone cubique ou quadratique a l'etat de traces. Bien qu'un modele de type Prout et Tompkins fournisse une bonne representation des phenomenes, les observations morphologiques effectuees parallelement a l'etude cinetique indiquent une transformation regie par un processus d'interface, ce que confirme la loi de vitesse en fonction de la pressionAdditional details
