COMPOSITE COATING FROM METAL AND CNT AND/OR FULLERENES ON STRIP MATERIALS Russian patent published in 2013 - IPC C23C28/00 C23C16/26 C23C16/56 B82Y30/00 

FIELD: metallurgy.

SUBSTANCE: metal strip contains a coating from carbon nanotubes and/or fullerenes soaked with metal chosen from the group consisting of Sn, Ni, Ag, Au, Pd, Cu, W or their alloys. Method for obtaining metal strip with the coating from carbon nanotubes and/or fullerenes and metal involves the following stages: a) application of diffusion barrier layer from transition metal Mo, Co, Fe/Ni, Cr, Ti, W or Ce onto a metal strip, b) application of a nucleation layer from metal salt containing metal chosen from the group Fe, the 9-th or the 10-th subgroup of the periodic table onto the diffusion barrier layer, c) introduction after stages a) and b) of treated metal strip to hydrocarbon atmosphere containing organic gaseous compounds, d) formation of carbon nanotubes and/or fullerenes on metal strip at temperature of 200°C to 1500°C, e) soaking of carbon nanotubes and/or fullerenes with metal chosen from the group containing Sn, Ni, Ag, Au, Pd, Cu, W or their alloys.

EFFECT: obtained metal strip with the coating has improved friction coefficient, increased transition resistance of a contact, increased resistance to friction corrosion, improved resistance to abrasion and increased ability to be deformed.
