Nanomodified Oxide Composite Structural Ceramics and Ultra-Jet Method for Evaluating Its Operational Properties

The paper presents the results of experimental studies of corundum composite ceramics with a modifier in the form of a nanopowder of boehmite (AIO (OH)). The study of the morphology of the samples using scanning electron microscopy by Carl Zeiss, Gemeni (Germany) shows that the introduction of boehmite improves the crack resistance of corundum ceramics. It is possible to determine the optimal content of boehmite using the method of ultra-jet diagnostics at the stage of technological preparation of the production of ceramic products. The proposed method can significantly shorten the time of testing of the corundum composite ceramics, reduce consumption of the material and other production costs.
