PURPOSE:To provide a surface treating method for an implantation material high in affinity with an organism, which can perform stable implantation, in treating the surface of an implantation material such as artificial bone, artificial dental roots, etc. CONSTITUTION:This is the surface treating which deposits calcium phosphate on the surface of an implantation material by inserting the implantation material 4 into the mixed aqueous solution 7 of a phosphate and a calcium compound, and performing current application by a power unit 9 between it and the mixed aqueous solution, using the implantation material as a cathode, and generating discharge condition while interposing electrolytically generated gas 10 on the surface of the implantation material, and as the pretreatment of the deposited surface treatment, the implantation material is cleaned with a fluoride aqueous solution 3, and the treatment for sticking the fluoride on the surface of the implantation material is performed. |
