PROCESS FOR PRODUCING MATERIAL FOR HARD TISSUE CONTACT TOOL, AND HARD TISSUE CONTACT TOOL

摘要

This invention provides a process for producing a material for a hard tissue contact tool, which can satisfactorily impart functionality and can improve surface treatment efficiency, and a hard tissue contact tool. The process for producing a material for a hard tissue contact tool comprises the step of subjecting an electroconductive material having a surface formed of at least one material selected from the group consisting of zirconium, a zirconium compound, and a zirconium alloy to cathode polarization treatment in an aqueous electrolyte solution containing an effective amount of hydrogen peroxide. The production process can produce a material for a hard tissue contact tool which can realize efficient precipitation of calcium phosphate on its surface upon implantation in a living body.
