Three different methods have been compared for preparing bioactive coatings on a titanium 
substrate – electrochemical deposition from electrolytes containing calcium nitrate and 
ammonium dihydrophosphate under cathodic polarization of titanium, plasma-electrolytic 
oxidation of titanium in solutions containing calcium citrate and ammonium dihydrophosphate 
and chemical modification of mesoporous anodic TiO2 films by calcium phosphate 
nanoparticles. The coatings prepared by cathodic electrodeposition demonstrate a low adhesion 
to the Ti substrate and consist of 30–80 % brushite, 20–70 % tricalcium phosphate and 5–22 % 
hydroxyapatite. Plasma-electrolytic oxidation leads to the formation of rather hard amorphous 
TiO2 films containing calcium pyrophosphate. Fairly good adhesion and excellent 
biocompatibility has been revealed for mesoporous anodic TiO2 films chemically modified with 
hydroxyapatite nanoparticles.
