Calcium phosphate coating on titanium substrate by a modified electrocrystallization process.

Modification of ethyl alcohol added aqueous electrolyte for depositing calcium phosphate on titanium substrates by a electrocrystallization method is described. Film coated in the electrolyte with ethyl alcohol addition is more homogeneous and the growth rate is higher. The optimum quantity of ethyl alcohol added is 50% of the electrolyte. Although the pH value of electrolyte varies as ethyl alcohol is added, the phases of the deposited film remain the same, and are hydroxyapatite and brushite. The development of the microstructure of the coated film during deposition is discussed. Copyright 1998 Chapman & Hall
