MULTIPURPOSE BIOCOMPATIBLE NANOSTRUCTUE MEMBRANULAS FOR MEDICINE Russian patent published in 2008 - IPC A61L27/10 A61C13/83 A61K6/04 B82B1/00 

FIELD: medical equipment.

SUBSTANCE: the invention refers to biocompatible wearproof nanostructure thin-film materials on the basis of titan carbonitride, used as membranulas for manufacturing imlants, working under load. Total concentration of the basic and additional elements in a covering has the following ratio: where X_i - total concentration of basic elements Ti, Ta, C, N in the covering, Y_j - total concentration of additional elements Ca, Zr, Si, K, Mn, O, P in a covering, concentration of elements in the covering being chosen at the following ratio of components, at.wt%: Ti - 30-50; Ta 6-50; C - 15-40; N - 0-35; O - 5-25; Ca - 0-7; Zr - 0-20; Si - 0-30; P - 0-1.5; Mn - 0-1.0; K - 0-1.0.

EFFECT: high hardness of covering; low elasticity module; high durability of coupling with a substrate; low factor of friction and rate of deterioration; high firmness to elastic deformation of destruction and plastic deformation; low roughness of the surface; negative charge of the surface in physiological mediums; bioactive surface; biocompatibility and absence of toxicity.
