Electrolytic depositions of calcium phosphates on substrate

  • H. Monma


Calcium phosphate deposition layers on cathode substrates were prepared by electrolysing acidic Ca(H2PO4)2·H2O (MCP) solutions of 0.02–0.21 mol dm−3 added with and without NaNO3 at cathode currents of 2–200 mAcm−2 at 20–90 °C. At relatively high MCP concentrations and low currents, CaHPO4·2H2O and CaHPO4 plate-like crystals were deposited below and above ∼30 °C, respectively. With increasing current, the deposits became fine. On further increasing the current and/or decreasing the MCP concentration, apatite deposition occurred. The addition of NaNO3 facilitated the formation of apatite. Deposited apatites were very fine grains and had a calcium-deficiency of ∼1.50 in the Ca/P molar ratio.
