Electrolytic calcium phosphate depositions on stainless steel were carried out by electrolyzing 0.21 mol/dm3 Ca (H2PO4)2. H2O solutions added with and without NaNO3 at a cathode current of mainly 6mA/cm2 at 20-90°C. CaHPO4 2H2 O formed below 30±5°C and CaHPO4 above the temperature. Both plate-like crystals were deposited nearly parallel to the stainless steel cathode face, and changed to fine grains with increasing current. By further increasing current or decreasing calcium phosphate concentration the formation of apatite became possible.
