Перспективы использования импульсного электронного пучка для модифицирования поверхности медицинских имплантатов

Abstract

One of the effective ways to improve the adhesive properties of biocompatible coatings on implants is the using of electron-beam melting of the surface, accompanied by a partial or complete mixing area "coating- substrate". The surface of the titanium substrate bearing calcium phosphate coating received by RF magnetron sputter is processed by a pulsed electron beam having an energy density of 0.8-8 J/cm{2}. After treatment by a pulsed electron beam under different regimes the significant changes in the topography of the formed surface were observed. Treatment regimes with an energy density of 0.8 J/cm{2} and 3 lead to the thermal annealing of the coating. The use of a beam having an energy density of the substrate of 8 and 6.5 J/cm{2} leads to partial vaporization and mixing the coating material with a titanium matrix.
