High-temperature stability of polycrystalline cubic boron nitride cutting tool materials in air
Source abstract
Abstract
Abstract Thermal stability of cubic boron nitride (cBN)–TiC cutting tool material in air was analyzed using TGA and oxidation tests in a muffle furnace within the temperature range 550–1100 °C for a holding time of 60 min. A scanning electron microscope equipped with an energy dispersive X-ray spectroscopy analysis system was particularly used for the characterization of the oxidation scales obtained thereafter. The significance of the results obtained was discussed in terms of oxidation kinetics law, oxidation mechanisms as well as variation of constitution and morphology of the oxidation scale with temperature, keeping focus on the machining context.
