EFFECT OF PH BUFFER ON ELECTROCHEMICAL DEPOSITION OF CALCIUM-PHOSPHATE

Calcium phosphate coatings containing carbonate apatite were deposited on pure titanium plate by an electrochemical method in the electrolyt es containing different amounts of Ca and P with and without trishydro xyaminomethane, a pH buffer. Results suggest that addition of pH buffe r into the electrolyte has a pronounced effect on the amount of produc ts on the titanium electrode, whereas the composition of the products is nearly independent of the Ca/P ratio in the electrolyte.
