Nanocomposite Coatings Produced by Friction Cladding

摘要

Copper matrix nanocomposites (materials for coatings) and reinforcements from nanodiamonds, nanosilica or diatomite were fabricated by mechanical alloying, and coatings were produced by the friction cladding method. Investigations included the study of material at all steps of the technological scheme: formation of granules during mechanical alloying; distribution of nanoparticles in the copper matrix after consolidation of granules; structure of coatings and distribution of reinforcements in the coatings. As the result of these investigations, optimal technological conditions of treatment were developed.
