METHOD OF PRODUCING NANOCOMPOSITE METAL-CERAMIC COATINGS WITH REQUIRED MICROHARDNESS VALUES Russian patent published in 2017 - IPC C23C14/06 B82Y30/00 G01N3/40 

FIELD: materials science.

SUBSTANCE: invention relates to materials science and can be used in various fields of state-of-the-art electronics, alternative power engineering and machine building. Method of producing nanocomposite metal-ceramic coatings with required microhardness values involves providing in the obtained coating a required percentage ratio of metal and ceramic phases at a certain chemical composition of the said phases, herewith determined are values of microhardness for a metal and a ceramic coatings of different chemical compositions free from impurities of the ceramic or the metal phases, respectively, then produced is a coating with a specified chemical composition and the specified percentage of the above said phases with a certain pitch with varying the percentage ratio of metal-to-ceramics phases in the coating from zero to maximum. Then determined are obtained values of the coating microhardness at the preset ratio of the above said phases. Basing on the obtained data an artificial neural network is created and trained, then the said artificial neural network is entered with data on chemical composition of the metal and the ceramic phases, percentage ratio of the said phases in the obtained coating, and by means of the artificial neural network determined is the obtained nanocomposite metal-ceramic coating microhardness value at the entered ratio of the metal and the ceramic phases. In particular cases the nanocomposite coating microhardness value is determined by recalculating the microhardness for a solid sample by entering a conversion coefficient.

EFFECT: provided is higher wear resistance at simultaneous reduction of the coating production cost and high stability of the determined parameters used for the coating application.
