Oxidation Kinetics of ZrB2-SiC Composites

摘要：

　　An oxidation kinetics model of hot-pressed ZrB2-SiC composites was established and then proved by experiments.The relationship between oxidation rate and temperature was attained by reaction activation energy and frequency factor at the different oxidation stages.Results showed that the relations between the oxidation gain of unit area and the oxidation time are linear,conic and parabolic,respectively,during the stage of the oxidation prophase,midterm and anaphase.
