In these tests, several kinds of surface roughness have been prepared at the range of Rmax value between 25μm and 2.5μm by turnning, file- or sandpaper-grinding, or buffing. The transcription of surface roughness between pairing test pieces and the transition of Rmax values and roughness profiles of both test piece surfaces during the fatigue test running have been discussed in detail. As the result, it has been clarified that the effective roughness for the pitting failure arised only on the surfaces with lower rotational speed was that of the surfaces with higher rotational one, including the ranscribing roughness. Moreover, by using a and b as the surface roughness factor, the following equation has been introduced as to explain successfully the relationship between the increasing rate of pitting failure (Δd) and the repetitive rolling nmuber (N):Δd=aNb. In this equation, a and b are seemed to be related to the quantity and the quality of the surface roughness, respec tively.","subitem_description_type":"Abstract"}]},"item_3_description_64":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"長崎大学教育学部自然科学研究報告. vol.42, p.85-93; 1990","subitem_description_type":"Other"}]},"item_3_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"31575","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Furuya, Yoshio"}]}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"長崎大学教育学部"}]},"item_3_relation_29":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"40002768819","subitem_relation_type_select":"NAID"}}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00178280","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0386443X","subitem_source_identifier_type":"ISSN"}]},"item_3_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"古谷, 吉男"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-21"}],"displaytype":"detail","filename":"kyoikuS42_085.pdf","filesize":[{"value":"2.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kyoikuS42_085.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/7544/files/kyoikuS42_085.pdf"},"version_id":"1cb08898-742f-49c3-bca2-614d3776cdee"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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":"鋼のピッチング疲労損傷に及ぼす表面あらさの影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"鋼のピッチング疲労損傷に及ぼす表面あらさの影響"}]},"item_type_id":"3","owner":"2","path":["549"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-06-24"},"publish_date":"2013-06-24","publish_status":"0","recid":"7544","relation_version_is_last":true,"title":["鋼のピッチング疲労損傷に及ぼす表面あらさの影響"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T02:22:10.184338+00:00"}
