In this study, the initial scaling sites on carbon steel with corrosion product were investigated and scaling mechanisms were discussed. Carbon steel sheets were immersed in a solution supersaturated condition for magnesium silicate under normal standard state.\nScaling at a corroded part on carbon steel was easier to occur than that at non-corroded part on carbon steel. The corrosion product was comprised of Fe2O3 (Hematite), Fe3O4 (Magnetite), and β-FeOOH (Akaganeite). When the particles of Fe2O3, Fe3O4, and β-FeOOH were individually immersed in the solution, the formation of magnesium silicate occurs only on β-FeOOH.\nOne of the preferred scaling sites for magnesium silicate was β-FeOOH. The physical and chemical interactions were investigated. The physical interactions were evaluated by zeta potential, and the results suggested that the repulsion occurs between them.\nOn the other hand, the chemical interaction was evaluated by IR and Raman analyses. Only IR spectrum of β-FeOOH changed. The change was derived from absorption range of Fe–OH in β-FeOOH. The OH group in β-FeOOH may react with silanol group by the dehydration-condensation reaction."}]},"item_3_description_63":{"attribute_name":"研究課題番号","attribute_value_mlt":[{"subitem_description":"19H02453"}]},"item_3_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本鉄鋼協会"}]},"item_3_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.2355/isijinternational.ISIJINT-2022-021","subitem_relation_type_select":"DOI"}}]},"item_3_relation_13":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"Publisher's Version/PDF (OpenAccess)"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.2355/isijinternational.ISIJINT-2022-021","subitem_relation_type_select":"DOI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"日本鉄鋼協会"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.isij.or.jp/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"KAKEN研究課題: 地熱水中で形成したスケールの構造解析とそれに基づく材料のスケール性評価手法の確立"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://id.nii.ac.jp/1342/00002520/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"研究代表者: 盛田 元彰 (東京海洋大学)"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://nrid.nii.ac.jp/ja/nrid/1000030636626/","subitem_relation_type_select":"URI"}}]},"item_3_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0915-1559","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA10680712","subitem_source_identifier_type":"NCID"}]},"item_3_subject_64":{"attribute_name":"科学研究費研究課題","attribute_value_mlt":[{"subitem_subject":"地熱水中で形成したスケールの構造解析とそれに基づく材料のスケール性評価手法の確立"},{"subitem_subject":"Microstructural analysis of scale formed in the geothermal water and development of evaluation method for scaling property of materials"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Koyama, Sota"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Inaba, Norifusa"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Morita, Motoaki"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"Motoda, Shin-ichi"}],"nameIdentifiers":[{},{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"scaling","subitem_subject_scheme":"Other"},{"subitem_subject":"fouling","subitem_subject_scheme":"Other"},{"subitem_subject":"silica","subitem_subject_scheme":"Other"},{"subitem_subject":"magnesium silicate","subitem_subject_scheme":"Other"},{"subitem_subject":"corrosion product","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"}]},"item_title":"Preferential Site for Scaling on Carbon Steel with Corrosion Products","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Preferential Site for Scaling on Carbon Steel with Corrosion Products"}]},"item_type_id":"3","owner":"15","path":["517","518","519","650"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-11-21"},"publish_date":"2022-11-21","publish_status":"0","recid":"2584","relation_version_is_last":true,"title":["Preferential Site for Scaling on Carbon Steel with Corrosion Products"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2023-07-25T10:28:45.064211+00:00"}
