FIELD: chemistry.
SUBSTANCE: method of making an article from a titanium-alloy alloy with a nanoporous surface involves making an article with a porous surface from sintered powder of titanium-aluminium alloy with granular size of 1-10 mcm, washing the article in ethanol, drying, washing in distilled water, drying at temperature of 80-90°C and forming a nanoporous oxide on the surface of the article by anodic treatment in 10.0% sulphuric acid solution with addition of 0.15% hydrofluoric acid with constant current density.
EFFECT: high specific surface area of articles.
