Kinetic Research of Oxidation Induced Crack Healing of Engineering Ceramics ( Ⅰ ) Theoretical Model
|
Abstract:
Oxidation reaction induced crack healing is one kind of very important methods to improve the strength of engineering ceramics. The quantitative relation among crack healing, oxidation reaction, and strength improvement were researched. A crack healing model was established and the kinetic analysis of crack healing studied. The effects of time, temperature, and crack size on crack healing were also studied. The purpose of this paper is supplying theory foundation for quantitative study of crack healing and exact controlling of crack healing.
