Abstract
Ultrafine-grained, nanophase coatings of hydroxyapatite were synthesiz ed by electrocrystallization from dilute electrolytes ([Ca] = 6.1 x 10 (-4) M, [phosphate] = 3.6 x 10(-4) M) at pH values comparable with the biological pH. At these comparatively low supersaturations, hydroxyap atite is shown to be precipitated without the formation of a precursor phase. A description of the sequence of events occurring at the elect rode-electrolyte interface is given to explain the mechanism involved in the direct formation of nanophase hydroxyapatite on polarized elect rodes.
