Morphologies of Hydroxyapatite Crystal Deposited on Titanium Surface with Electrochemical Technique

Article Preview

Homogeneous coatings adhered strongly to titanium substrates were attained by electrochemical method in electrolytes containing Ca2+ and PO4 3- ions with Ca/P ratio being 1.67. SEM observation showed that the HAp crystals prepared with higher concentration electrolyte (4x10-2M Ca2+) are ribbon-like with thickness of nanometer size, a morphology seldom reported previously. In an electrolyte of lower concentration (6x10-4M Ca2+), the HAp crystals formed are rod-like with defined hexagonal cross section and diameter of about 70-80nm. The electrolyte of intermediary concentration (5x10-3M Ca2+) produced plate-like HAp crystals. XRD patterns and IR spectra confirmed that the coatings consist of HAp crystals.
