Abstract

The object of study is a multi-layer composition «steel – a material with shape memory effect (SME) – wear-resistant layer» (TiNiHf - WC-Mo-Co). Ni was deposited as an adhesion layer. The sequence of functional layers deposition, their composition, thickness, structural-phase state and dispersion are determined by the operating conditions and operated by processing modes. To enhance durability and longevity it is recommended to form a layer with shape memory effect in a way that its temperature, given the increase in friction, corresponded to martensitic state and had an increased relaxation and damping capacity to inhibit cracking.
