Technological aspects of creating structural ceramics using nano-sized boehmite powder and the possibility of its ultrajet diagnostics

Modern domestic structural ceramics is inferior to foreign analogues in a number of parameters, which explains the relevance of this paper. A solution to this problem is not only to improve the production process but also the structural composition of the initial material, as well as rapid methods to assess the properties of the final composition. This paper deals with the creation of structural ceramics based on nanoscale boehmite powder to improve technological, operational, and ballistic properties of structural composite ceramics. The results of the micromorphology analysis of structural ceramics chips after static and dynamic loading are compared. The obtained results are discussed and conclusions are drawn about the possibility of using the ultrajet diagnostic method at the technological preparation stage instead of expensive and time-consuming field tests with solid high-speed drummers. It is suggested that the ultrajet method for estimating performance (dynamic) properties of ceramics could be integrated with the diagnostic method based on measuring acoustic emission waves. The efficiency of ultrajet diagnostic methods is justified and the prospects of its application in the manufacture of structural composite ceramics are discussed. The main advantage of the method is the ability to diagnose a material in the laboratory, which is important for choosing technological processes at the preparation stage.
