METHOD FOR INCREASING WEAR RESISTANCE AND ANTI-CORROSION PROPERTIES OF STEEL PRODUCTS Russian patent published in 2022 - IPC C23C28/00 A61L27/30 C23C14/35 C23C14/16 C23C14/30 

FIELD: materials science.

SUBSTANCE: invention relates to the field of materials science, metal surface treatment and can be used in medicine to increase the wear resistance and anti-corrosion properties of steel products, for example, medical implants. The method for obtaining a wear-resistant anticorrosive coating on an item made of stainless steel grade AISI 316L (03X17N14M3) includes the creation of a Ti-based surface alloy on the item in a single vacuum cycle by alternating the operations of spraying a titanium film by magnetron sputtering and its subsequent liquid-phase mixing with the material of the item using irradiation by a low-energy high-current electron beam (LEHCEB) with a pulse duration of 2-3 mcs, a number of pulses from 3 to 5 and an electron energy density of 2-3 J/cm². A silicon-carbon (α-C:H:SiO_x) finishing coating is then applied to the product.

EFFECT: invention provides a coating that has increased wear resistance and corrosion resistance, having a layer (α-C:H:SiO_x), which has a high biocompatibility with the human biological environment due to the presence of silicon.
