Apatite formation in the body is required for artificial materials to bond to bone. We have shown that apatite can form on NaOH- and heat-treated Hf in simulated body fluid, although the degree of apatite formation is not high. In this study, we investigated apatite formation on surface-modified Hf metal in simulated body fluid. Hf substrates were soaked in NH4F solution or electrochemically polarized in H2SO4 or NH4F solution, followed by heating at 600°C. The sample soaked or cathodically polarized in NH4F solution had porous structure, and the anodically polarized sample had nanotube aggregates on its surface. F was incorporated into the sample polarized in NH4F solution, but not the sample merely soaked in the solution. NH4F was more effective than H2SO4 in facilitating apatite formation. Remarkably, the sample soaked in NH4F solution had the highest apatite-forming ability. Its porous structure was considered to play a dominant role in apatite formation. Furthermore, there was little correlation between surface energy and apatite formation. Notably, NH4F treatment is more effective than the previously reported NaOH and heat treatments in promoting apatite formation.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_21_link_62":{"attribute_name":"研究者情報","attribute_value_mlt":[{"subitem_link_url":"https://hyokadb02.jimu.kyutech.ac.jp/html/323_ja.html"}]},"item_21_publisher_7":{"attribute_name":"出版社","attribute_value_mlt":[{"subitem_publisher":"Taylor & Francis"}]},"item_21_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1080/21870764.2022.2034249","subitem_relation_type_select":"DOI"}}]},"item_21_rights_13":{"attribute_name":"著作権関連情報","attribute_value_mlt":[{"subitem_rights":"Copyright (c) 2022 The Author(s).
