METHOD FOR OBTAINING HIGHLY POROUS OSTEO-INTEGRATING COATING ON IMPLANTS FROM TITANIUM ALLOYS

摘要

FIELD: metallurgy.;SUBSTANCE: method comprises thermodiffusion hydrogen saturation of the implant and vacuum annealing. Before thermodiffusion hydrogen saturation and vacuum annealing, a porous coating is applied on the surface of the implant by diffusion welding with the help of welding of titanium alloy fibres at a temperature of 850-950°C to the surface of the implant from titanium alloys, hydrogen saturation is carried out at a temperature of 600-650°C to a hydrogen concentration of 0.5-0.8 wt %, and the subsequent vacuum annealing - to a hydrogen concentration of not more than 0.008 wt %.;EFFECT: shearing force of the coating is increased from the monolithic substrate while maintaining its structure and properties.;4 cl, 1 dwg, 1 tbl, 8 ex
