METHOD OF PRODUCTION OF COATINGS Russian patent published in 2006 - IPC C23C4/04 C23C4/18 

FIELD: medical equipment; methods of production of coatings.

SUBSTANCE: the invention is pertaining to the field of medical equipment, in particular, to the method of production of coatings and may be used at application of the porous morphologically significant coatings on the articles of the medical equipment. The offered method provides for sputtering on the substrate by the plasma spray of the coating or the sublayer with the coating and usage in the capacity of the coating or the sublayer of the alloy containing the fundamental component of the substrate or the substrate and the coating in the amount smaller, than it is necessary for formation of an eutectic, and the second component forming the eutectic with the fundamental component as a result of the contact smelting. At that the components of the alloy are selected considering the possibility of formation by them of no less than two eutectics: one eutectic - more fusible and the other eutectic with the fusion point exceeding the fusion point of the first one, but at the greater content of the second component, and no less than one resistant chemical compound, in which the concentration of the components takes an intermediate position between the concentrations of the components in these eutectics and with the concentration of the components taking the intermediate position between the chemical compound and the eutectic with the greater fusion point; and the heat treatment within the range of the temperatures above the fusion point of the more fusible eutectic and below the fusion point of other eutectic for formation and smelting of the eutectic in the zone of the contact of the substrate - the coating or the substrate - the sublayer and the sublayer - the coating. The invention ensures the high strength of cohesion of the coating with the substrate.

EFFECT: the invention ensures the high strength of cohesion of the coating with the substrate.
