ELECTROCHEMICAL IMMERSION METHOD IN AN AQUEOUS ELECTROLYTE FOR PRODUCING A BIOLOGICALLY DEGRADATION STABLE SURFACE LAYER ON BASE BODIES MADE OF TITANIUM OR TITANIUM BASED ALLOYS

摘要

The invention relates to an electrochemical immersion method in an aqueous electrolyte for producing a biologically degradation-stable surface layer on base bodies made of titanium or titanium based alloys with anodic polarity of the base body. According to the invention, the electrolyte is formed as an aqueous solution from the components 0,05 - 0,5 mol/l calcium disodium ethylene diamine tetraacetic acid (C10H12N2O8CaNa2), 0.05 - 0.5 mol/l ammonium dihydrogen phosphate (NH4H2PO4), 0.5 - 5.0 mol/l hydrogen peroxide (H2O2) and 0.003 - 0.03 mol/l pyridine-2.6-dicarboxylic acid (C7H5O4N).
