FIELD: metallurgy.
SUBSTANCE: method comprises treating powdered sponge titanium articles in an ultrasonic bath sequentially in ethanol and water for 10-12 minutes, then drying at 90°C and anodization in a fluorine-containing sulfuric acid solution for 30-60 minutes, followed by washing in water and drying at 90°C.
EFFECT: increased specific surface of the article, imparting hydrophilic properties to the article surface, the method does not require involvement of complicated equipment and high energy costs.
