< Topic > Making use of acid offer of the expedient which locks the calcium phosphate on the metal surface with the processing method the residue being little.Solutions The calcium phosphate connecting to the surface of the backing material, being production method of the calcium phosphate mixture which becomes, after making the coupling agent the surface of the above-mentioned backing material contact, making the silane coupling medicine contact, the surface finishing process and the description above which process after the finishing process, the connection process which makes the above-mentioned calcium phosphate the silane coupling medicine of the surface of the above-mentioned backing material after the polymerization process and the polymerization process connect which make the polymerization of the silane coupling medicine start with the polymerization initiator and, it includes, the above-mentioned backing material is the metal, the production method of featuring that the above-mentioned coupling agent is the ozone water.< Selective figure > Figure 2【課題】 酸を用いずに残留物の少ない処理方法により金属表面にリン酸カルシウムを固定する手段の提供。【解決手段】 基材の表面にリン酸カルシウムが結合してなるリン酸カルシウム複合体の製造方法であって、上記基材の表面に表面処理剤を接触させた後に、シランカップリング剤を接触させて表面処理する表面処理工程と、上記表面処理工程後に、重合開始剤によりシランカップリング剤の重合を開始させる重合工程と、重合工程後の上記基材の表面のシランカップリング剤に上記リン酸カルシウムを結合させる結合工程と、を含み、上記基材が金属であり、上記表面処理剤がオゾン水であることを特徴とする製造方法。【選択図】 図2
