Abstract

The invention relates to the method for electrochemical surface treatment of biomedical product made of titanium or Ti-based alloys characterized in that it comprises the steps: Immersion of the degreased and cleaned biomedical product into the electrolyte consisting of Reline or Glyceline; galvanostatic etching treatment of the biomedical product at the current density 1 to 20 mA cm-2 for 5 to 60 min. at a temperature 15 to 40 °C or potentiostatic etching treatment of the biomedical product at the potential 1 to 5 V for 5 to 60 min. at a temperature 15 to 40 °C; or galvanostatic electropolishing of the biomedical product at the current density 25 to 100 mA cm-2 for 5 to 60 min. at a temperature 15 to 40 °C or potentiostatic electropolishing of the biomedical product at the potential 6 to 30 V for 5 to 60 min. at a temperature 15 to 40 °C; and subsequent cleaning of the biomedical product from electrolytes residuals.
