The Stressed State of the Boundary Between Ceramic and a Coating Under the Effect of Power Loads

A technique for the investigation of the stressed state of the boundary between ceramic and a coating is developed. The basic laws governing the development of stresses in the boundary layers of nitride ceramic and a coating made of titanium nitride under the effect of concentrated and distributed forces are found with the use of the technique. The need to take into account the stressed state of a ceramic — coating boundary in the course of analyzing the wear and degradation of ceramic parts in the course of design, manufacture, and service is noted.
