METHOD OF APPLYING NANOSTRUCTURISED WEAR-RESISTANT ELECTROCONDUCTIVE COVERINGS Russian patent published in 2009 - IPC C23C24/04 B82B3/00 

FIELD: chemistry.

SUBSTANCE: invention relates to methods of applying electroconductive nanostructurised coverings with high electroconductivity and wear-resistance. Method includes supply of powder composition with reinforcing particles from four measuring apparatuses into supersonic stream of heated gas and application of powder composition on product surface. First, from first measuring apparatus reinforcing ultra-dispersive particles of ZrO₂ with fraction from 0.1 to 1.0 mcm are supplied and product surface is processed until juvenile surface is formed. Then powder composition based on Cu or Al is applied on product surface by supplying powder from four measuring apparatuses. From the first measuring apparatus reinforcing ultra-dispersive ZrO₂ particles are supplied, from the second - Cu or Al powder, form the third - reinforcing nanoparticles of quasi-crystalline compound of system Al-Cu-Fe, and from the fourth measuring apparatus - reinforcing particles Y₂O₃. Rate of heterophase flow during application of composition based on Cu or Al is changed within the range from 450 to 750 m/sec.

EFFECT: reduction of porosity, increase of wear-resistance, adhesive and cohesive strength of covering preserving its high electroconductivity.
