THE DEVELOPMENT OF VITREOUS COUPLING AGENTS USED FOR THE PRODUCTION OF ABRASIVE TOOLS
Published: 1 Jul 2016
Abstract: The interaction process of glass with cubic boron nitride has been studied under dynamic and isothermal conditions. It has been revealed that the interaction of moldering glass with βBN is accompanied by the glass crystallization. The beginning of the crystallization process is demonstrated by anomalous chаnge of the glass viscosity within the temperature range of 420-440°C. The study of microstructure has discovered that the formation of crystalline phase on the interface of “melt – βBN” suppresses the abrasive oxidation.
