MULTICOMPONENT BIOACTIVE NANOCOMPOSITE COATING WITH ANTIBACTERIAL EFFECT Russian patent published in 2014 - IPC A61L27/02 A61K6/02 B82Y5/00 A61L27/06 B82B1/00 

FIELD: chemistry.

SUBSTANCE: coating is based on titanium carbonitride with addition of additional elements which provide the required set of mechanical and tribological properties, as well as biologically active and antibacterial properties. Overall concentrations of basic and additional elements are in the following ratio: $$\mathrm{1,2}<\frac{\sum X_i}{\sum Y_j}<\mathrm{20,}$$ where X_i is the overall concentration of basic elements Ti, C, N in the coating, Y_j is the overall concentration of additional elements Ag, Ca, Zr, Si, O, P, K, Mn in the coating.

EFFECT: coating has high hardness, low modulus of elasticity, high value of elastic recovery, low coefficient of friction and rate of wear in different physiological media.
