First, the fatigue tests of the hypoxia vacuum melting case-carburized Cr-Mo-Si steel and Cr-Mo steel were carried out by using a 2-roller-type contact fatigue testing machine. Secondly, the changes of surface temperature, surface failure, surface roughness and hardness in test rollers were examined with the use of a thermocouple, a scanning electron microscope, a surface roughness measuring instrument and a penetrometer. In the Cr-Mo-Si steel test rollers under the rolling-sliding contact condition, the following results are obtained in comparison with the Cr-Mo steel test rollers: (1) It is possible to decrease the size of micro pits. (2) The micro pitting area ratio against contact stress cycles decreases under the medium load condition. (3)The pits and spalls don’t occur under the heavy load condition. (4) The fatigue (spalling) life is improved. (5) The amount of wear on the contact surface is decreased. (6) There is little change of surface hardness under the high temperature. Therefore, it is clear that the developed Cr-Mo-Si steel can be applied to the case-carburized gear materials for high load condition. The main reason is that the surface hardness of the developed Cr-Mo-Si steel is harder than that of the Cr-Mo steel under the same surface temperature.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"JSME-KSME Joint International Conference of Manufacturing, Machine Design and Tribology\nFinal Program　p.30","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Redda, Daniel Tilahun","creatorNameLang":"en"}],"familyNames":[{"familyName":"Redda","familyNameLang":"en"}],"givenNames":[{"givenName":"Tilahun Daniel","givenNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"6235","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中西, 勉","creatorNameLang":"ja"},{"creatorName":"ナカニシ, ツトム","creatorNameLang":"ja-Kana"},{"creatorName":"Nakanishi, Tsutomu","creatorNameLang":"en"}],"familyNames":[{"familyName":"中西","familyNameLang":"ja"},{"familyName":"ナカニシ","familyNameLang":"ja-Kana"},{"familyName":"Nakanishi","familyNameLang":"en"}],"givenNames":[{"givenName":"勉","givenNameLang":"ja"},{"givenName":"ツトム","givenNameLang":"ja-Kana"},{"givenName":"Tsutomu","givenNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"5610","nameIdentifierScheme":"WEKO"}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":"0000000106573887","affiliationNameIdentifierScheme":"ISNI","affiliationNameIdentifierURI":"https://isni.org/isni/0000000106573887"}],"affiliationNames":[{"affiliationName":"宮崎大学","affiliationNameLang":"ja"},{"affiliationName":"University of Miyazaki","affiliationNameLang":"en"}]}],"creatorAlternatives":[{"creatorAlternative":"鐙, 鋼","creatorAlternativeLang":"ja"},{"creatorAlternative":"トウ, コウ","creatorAlternativeLang":"ja-Kana"},{"creatorAlternative":"Den, Gan","creatorAlternativeLang":"en"}],"creatorNames":[{"creatorName":"鄧, 鋼","creatorNameLang":"ja"},{"creatorName":"デン, ガン","creatorNameLang":"ja-Kana"},{"creatorName":"Deng, Gang","creatorNameLang":"en"}],"familyNames":[{"familyName":"鄧","familyNameLang":"ja"},{"familyName":"デン","familyNameLang":"ja-Kana"},{"familyName":"Deng","familyNameLang":"en"}],"givenNames":[{"givenName":"鋼","givenNameLang":"ja"},{"givenName":"ガン","givenNameLang":"ja-Kana"},{"givenName":"Gang","givenNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"5526","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"90237040","nameIdentifierScheme":"e-Rad_Researcher","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=90237040"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Gear","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Roller","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Material","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Alloy Steel","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Carburizing","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Surface Failure","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Surface Durability","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Surface Roughness","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Hardness","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":"item_resource_type","attribute_value_mlt":[{"resourcetype":"conference output","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Surface Durability of the Developed  Cr-Mo-Si Steel under the  Rolling-Sliding Contact Condition","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Surface Durability of the Developed  Cr-Mo-Si Steel under the  Rolling-Sliding Contact Condition","subitem_title_language":"en"}]},"item_type_id":"10005","owner":"9","path":["73","51"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-04-04"},"publish_date":"2024-04-04","publish_status":"0","recid":"2000603","relation_version_is_last":true,"title":["Surface Durability of the Developed  Cr-Mo-Si Steel under the  Rolling-Sliding Contact Condition"],"weko_creator_id":"9","weko_shared_id":-1},"updated":"2024-12-10T00:01:46.319032+00:00"}
