Abstract

We studied an impact of the technological processes, used for forming С/Сu composite coated surface of medical implants, on the mechanical characteristics and biocompatibility of resulting coatings. These implants, designed for temporary functioning, were made from X12CrNiTi18-9 stainless steel by ion-beam modification (IBM) of copper ions in a carbon dioxide environment. The optimal technological parameters of modifying steel samples were determined: an acceleration voltage is U║ = 100-150 kV and a radiation dose is F = (1-4) · 1017 ion/cm2. The data on secondary ionic mass spectrometry (SIMS) and laser emission microspectral analysis indicated that the presence of 2-5% Cu content in the C/Cu coating composite on the surface of medical products (e.g. osteofixation devices), made from chromium-nickel steel, provided them with required bacteriostatic quality.
