FIELD: chemistry.
SUBSTANCE: titanium implant etchant contains phosphoric acid, an oxidant and water in the following quantitative ratios of components, wt %: phosphoric acid 23-65, hydrogen peroxide 3-30, water - the balance.
EFFECT: invention enables to obtain a selective titanium etchant, having a low rate of etching, which enables to control the thickness of the etched layer and forms a residual layer of non-stoichiometric titanium phosphates which provide chemical affinity to phosphorus-containing bioactive coatings made from hydroxyapatite, which is the basic substance of bone tissue.
