Abstract
For the composite construction of the surface layer, we carried out the selected composition materials, methods and means of formation. A multilayer composition "steel - material with shape memory effect (SME) - wearproof layer» (TiNiZr - cBN-Co) was obtained by high-velocityoxy-fuel spraying in a vacuum. The sequence of functional layers’deposition, their composition, thickness, structure-phase state and dispersity were determined by operating conditions and are controlled by the processing modes. To enhance the survivability and longevity,it is recommended to form the SME layer so that its temperature, given the increase in friction, correspondedto the martensitic state and had increased relaxation and damping capacity in order to slow down cracking.
