FIELD: ceramic industry.
SUBSTANCE: invention can be used for determination of strength of a coating from ceramic nanoparticles. Core of the invention is that the method of determining strength of a coating from ceramic nanoparticles involves arranging a substrate with the coating from ceramic nanoparticles applied on its surface in a scanning electron microscope, evacuating the microscope to the state of high vacuum, setting a scanning magnification sufficient for rendering nanoparticles, scanning the coating at a tangent to the substrate by an electron beam of maximum allowable energy at gradual increase in current until the nanoparticles are taken off the coating, and the strength of the coating is determined by the current, in which there is the nanoparticles separation from the coating.
EFFECT: technical result is the possibility of determining strength of a coating from ceramic nanoparticles.
