Abstract

The purpose – receiving a nanostructural electrochemical covering Ni-Co-Cr (Cr-NiCo) alloy with a high microhardness. The composition of electrolyte (a ratio of ions of metals in solution – Cr58.6Ni22.5Co18.9 (α-Cr + β-Ni + NiO); Ni58.7Cr25.0Co16.3(β-Ni + α-Cr)), optimum phase structure by means of 4 criteria of a phase formation. The nanostructure of d=50 of nanometer is received by means of special multifunctional additives. In the presence of H-acid a covering of Cr-Ni-Co HV = 690 MPa, and for (NH2)2CO additive – HV = 985 MPa possesses. Alloys are recommended for use in radioelectronics and microelectronics for resistor and the strain-resisting elements.
