Abstract
Abstract—A method of estimating the mechanical properties of the surface layer of working elements made of polycrystalline superhard composites based on cubic boron nitride involving sclerometry at scanning by a diamond indenter has been proposed. Theoretical validation of the method has been provided and thermodynamic parameters of mechanical properties of the surface layer (the value of the activation barrier of initiation of the entropy production process and the capacity for entropy production at a metered impact) have been investigated. Results of the experiments on the performance efficiency of cutter tools made of superhard composites fabricated by lathing of tempered steel are provided and corroborate the theoretical assumptions.
