Studying of Diffusion of the Titan in Corundum Ceramics
Abstract: For increase in hardness (durability) and fire resistance (stability to melts metals) corundum ceramics on the basis of Al2O3 authors of the present work have suggested to protect for the first time its surface stronger and fire-resistant coverings, for example, from TiB2. In work results of high-temperature diffusion TiB2 in a surface of plates from Al 2O3 are shown. For the first time the method cathodeluminescencium (KL) for identification and a condition of atom Ti after diffusion is used, in for an establishment of its quantity used method X-ray spectrum the microanalysis (RSMA). Durability increase defined a method microindentification by means of a pyramid of Knoop and strength at a bend. Researches have shown perspectivity of hardening of a surface corundum ceramics and use of the above-stated methods for studying of results of diffusion.
