REFRACTORY AND CERAMIC MATERIALS/STRUCTURAL AND PHASE TRANSFORMATIONS IN ELECTRICAL SPARK MODIFICATION IN A CERAMIC-CERAMIC SYSTEM

摘要

The composition and structure of the surface layer and kinetics of electric-stimulated mass transfer in electrical spark alloying in ceramic-ceramic systems are studied. It is established that the mechanism underlying the kinetics of mass transfer typical for metallic electrical spark surfaces is three-stage in nature. Electrical spark modification of the surface of composite materials is shown to be possible.
