FIELD: metallurgy.
SUBSTANCE: proposed method comprises formation of porous anodic oxide layer by anode oxidation of titanium specimen at controlled potential electrolysis in nonaqueous electrolyte solution. Note here that after said formation, anodic oxide is separated by electrochemical process in weak aqueous solution of inorganic acid by cathodic polarisation of titanium specimen controlled potential electrolysis. Then, secondary layer of porous anodic titanium oxide is formed under the above described conditions. Note that anodic oxidation of titanium specimen for formation of both said layers is conducted at thermal stabilisation of electrochemical reaction.
EFFECT: better reproducibility of the process and high degree of nanostructure order.
