Aspolished and abraded surfaces were characterized by means of EPMA, XPS, XRD, and hardness test. Oxygen in the mirror-polished surface was uniformly distributed at the lowest level. Comparatively, abrading with SiC papers increased the surface oxygen amount and hardness. Owing to its excellent abrasivity, the coarse grit efficiently scratched the surface and hindered the regenerated oxide film from growing thick, but allowed only the metal-oxide interfacial gradient zone to extend. But, the fine grit merely rubbed the surface and allowed both the oxide film and interfacial zone to extend. Further, the surface appeared to be lightly yellow-colored, suggesting that the oxide film was thicker, probably within 10nm, than the nominal one. When compared with the bulk, the interfacial zone was rich in oxygen and therefore subjected to high coherency strain, which was introduced to relieve the great lattice mismatch between the outer and inner layers of titanium substrate. Effects of solute oxygen hardening and strain hardening were speculated to be responsible for the surface hardening of both SiC-abraded surfaces. In conclusion, abrading with a coarse grit led to accumulation of a high, non-uniform strain in the titanium substrate, thereby hardening the surface further.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本歯科理工学会","subitem_publisher_language":"ja"}]},"item_5_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.4012/dmj.25.13","subitem_relation_type_select":"DOI"}}]},"item_5_relation_31":{"attribute_name":"異版である","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110004498250","subitem_relation_type_select":"URI"}}]},"item_5_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"日本歯科理工学会"},{"subitem_rights":"本文データは学協会の許諾に基づきCiNiiから複製したものである"}]},"item_5_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA10443149","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0287-4547","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Miyakawa, Osamu","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"4669","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Okawa, Seigo","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"4670","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kobayashi, Masayoshi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"4671","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-07-29"}],"displaytype":"detail","filename":"25_1_13-19.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"25_1_13-19.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/1626/files/25_1_13-19.pdf"},"version_id":"c134f3e0-8508-4c8b-a6af-0d00d4a06f3b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Titanium","subitem_subject_scheme":"Other"},{"subitem_subject":"Abrading","subitem_subject_scheme":"Other"},{"subitem_subject":"Oxygen","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Abranding increases oxygen and hardness of titanium surface","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Abranding increases oxygen and hardness of titanium surface","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","478"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2012-06-04"},"publish_date":"2012-06-04","publish_status":"0","recid":"1626","relation_version_is_last":true,"title":["Abranding increases oxygen and hardness of titanium surface"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-15T03:34:23.175362+00:00"}
