Wear- and corrosion-resistant nanostructured functional coating obtained by high-speed cold gas-dynamic spraying
https://doi.org/10.22349/1994-6716-2025-121-1-40-46
Abstract
The paper presents the results of developing the optimal composition of a precision copper-nickel alloy, from which composite powders, the surface of which is plated with titanium diboride, are obtained by highspeed mechanosynthesis. Functional coatings are made from the composite powders by cold gas-dynamic spraying on a DIMET-3 unit. The resulting coatings are characterized by high microhardness (24–26 GPa) and have a long service life (10,000 hours).
