BIOCOATING FOR TITANIUM AND ALLOY IMPLANT AND METHOD FOR MAKING THEREOF |
摘要 |
FIELD: medicine. ^ SUBSTANCE: invention refers to medical equipment and can be applied for making a biocompatible coating of medical intraosseous and transosseous implant of high engraftment level. The titanium and alloy coating contains titanium and copper oxides in a certain quantitative ratio, and lanthanum. The coating is formed on titanium and titanium alloys (BT 1-0, BT 1-00, BT-6, BT-16 etc.) by the electrochemical method sequentially in two electrolytes; at first, anodic oxidation is used to make a layer of mixed titanium and copper oxides in electrolyte of concentration 200 g/l of sulphuric acid with added 50 g/l of copper sulphate in distilled water with direct anode current; then cathodic incorporation enables generation of a lanthanum layer in the form of fragments in electrolyte of concentration 0.5 M of lanthanum salicylate in dimethyl formamide with direct cathode voltage 3 V. ^ EFFECT: method allows making the osteointegration oxide biocoating exhibiting bactericidal and anticoagulant properties. ^ 2 cl, 1 ex |
