Calcium-deficient hydroxyapatite (DAp) crystals were deposited on a stainless steel from mixed solutions of calcium nitrate and ammonium hydrogen phosphate by electrochemical method. The electrolyte solution pH was adjusted to 5.0. Various morphologies of DAp were observed depending on bath temperature and current density. At room temperature and at low current densities, high crystalline calcium hydrogen phosphate, and at the same time, low crystalline hydroxyapatite-like product were obtained. At 50-80°C and at low current densities, narrow and long crystals oriented perpendicularly to the substrate in the deposits. At 80°C and at high current densities, c-axis-oriented plate-like crystals were deposited. The Ca/P molar ratios of the crystals obtained from solutions with Ca/P = 1.67 and 2.0 were nearly equal to 1.60 at higher current densities.
