THE INFLUENCE OF THE ALCOHOL-RESISTANT NITRIDE GLASSES COMPOSITION ON THEIR STRUCTURE AND PROPERTIES

Keywords: oxynitride glass; microhardness, crack resistance, tool composite

Abstract

The nitrogen introducing process into the molecular lattice of glasses by adding Si3N4 and using the remelting stage of oxynitride glasses was investigated. The influence of the composition of alkali-resistant nitride glasses on their structure and properties was studied. A significant increase in physic-mechanical properties (microhardness and crack resistance) is observed with the introduction of up to 4% (at.) nitrogen. Oxynitride glasses have increased chemical resistance. The combination of improved strength and increased chemical resistance has opened up significant potential for their use in instrumented composites. Microporous binders with high adhesion to the synthetic diamond surface were obtained and highly effective diamond-containing composites were created for the production of elite grinding wheels for precision grinding of complex profile products.
