HNO_3 solution. Both as -polished and cone. HNO_3 treated alloy surfaces were analyzed by Electron Spectroscopy for Chemical Analysis (ESCA) to explain the superior adhesive ability of the alloy surface treated with HNO_3. The surface of the HNO_3 treated specimen contains 25 at % Cr and 13% Ni and the as -polished specimen contains 17% Cr and 21% Ni. It shows that Cr, which has a good chemical affinjty for 4-META resin, is concentrated on the alloy surface. The Q lg spectra can be separated into three components: Component I is due to oxygen bonded with chromium in the passive film, Cr-OCr; II is due to oxygen bonded with both chromium and hydrogen in the passive film, Cr-OH ・ ・ ・ OH_2; and III is due to oxygen in physisorbed water molecules on the passive film. The area fractions are in the order II>I>III for the as-polished surface and I>II>III for the HNO_3 treated surface, indicating that a firm passive structure is formed on the surface treated by HNO_3 solution. This is the cause of the increase in the adhesive ability of the 4-META resin on the passive film.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_2_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN0008135X","subitem_source_identifier_type":"NCID"}]},"item_2_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Dental Materials Science, School of Dentistry, HIGASHI-NIPPON-GAKUEN UNIVERSITY/Department of Operative Dentistry, School of Dentistry, HIGASHI-NIPPON-GAKUEN UNIVERSITY/Second Department of Prosthodontics, School of Dentistry, HIGASHI-NIPPON-GAKUEN UNIVERSITY"}]},"item_2_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"東日本学園大学歯学部歯科理工学講座//東日本学園大学歯学部歯科保存学第II講座/東日本学園大学歯学部歯科補綴学第II講座"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1987-12-30"}],"displaytype":"detail","filename":"KJ00000094623.pdf","filesize":[{"value":"524.2 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"<Original>ESCA Study on Improvements in Adhesive Ability of Dental Adhesive Resin to Ni-Cr Alloy Treated by HNO_3 Solution","objectType":"fulltext","url":"https://hsuh.repo.nii.ac.jp/record/7355/files/KJ00000094623.pdf"},"version_id":"7740b7c7-ec41-4d66-b365-b164597391d1"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ESCA study","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Ni-Cr alloy","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"HNO_3 treatment","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"<Original>ESCA Study on Improvements in Adhesive Ability of Dental Adhesive Resin to Ni-Cr Alloy Treated by HNO_3 Solution","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"<Original>ESCA Study on Improvements in Adhesive Ability of Dental Adhesive Resin to Ni-Cr Alloy Treated by HNO_3 Solution","subitem_title_language":"en"},{"subitem_title":"<原著>Ni-Cr合金の濃硝酸処理による接着性向上のESCAによる解析","subitem_title_language":"ja"}]},"item_type_id":"2","owner":"17","path":["541"],"pubdate":{"attribute_name":"PubDate","attribute_value":"1987-12-30"},"publish_date":"1987-12-30","publish_status":"0","recid":"7355","relation_version_is_last":true,"title":["<Original>ESCA Study on Improvements in Adhesive Ability of Dental Adhesive Resin to Ni-Cr Alloy Treated by HNO_3 Solution"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-12-26T07:31:33.067859+00:00"}
