A ball and a flat disk made of SUS440C stainless steel were used as specimens. A surface of the as-received flat disk specimen was covered with a thick oxide layer (>40 nm). For an examination of the effect of the surface oxide layer on the tribological performance of the ionic liquids under high vacuum, another specimen with a thin oxide layer (approx. 4 nm thick) was prepared. The ionic liquids with the TFSA anion showed better lubrication performance with the thicker oxide layer specimen, whereas the ionic liquids with the BF4 anion showed superior performance with the thinner oxide layer specimen. These results are discussed based on the HSAB principle. It is shown that the mechanism of the opposite tribological characteristics can be reasonably explained in terms of the chemical hardness by the HSAB principle.","subitem_description_type":"Other"}]},"item_7_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: PA1510015000","subitem_description_type":"Other"}]},"item_7_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Springer US"}]},"item_7_relation_25":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"info:doi/10.1007/s11249-014-0353-9"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.1007/s11249-014-0353-9","subitem_relation_type_select":"DOI"}}]},"item_7_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1023-8883","subitem_source_identifier_type":"ISSN"}]},"item_7_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Tokyo Institute of Technology"},{"subitem_text_language":"en","subitem_text_value":"Tokyo Institute of Technology"},{"subitem_text_language":"en","subitem_text_value":"Tokyo Institute of Technology"},{"subitem_text_language":"en","subitem_text_value":"Tokyo Institute of Technology"},{"subitem_text_language":"en","subitem_text_value":"Tokyo Institute of Technology"},{"subitem_text_language":"en","subitem_text_value":"Idemitsu Kosan Co.
