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.
