These bearings made of SUS440C were self-lubricated with a glass cloth-reinforced PTFE retainer. In a previous study, the bearing exhibited excellent durability in at a speed of 50,000 rpm. XPS analysis indicated the intense formation of a chromic oxide (Cr2O3) layer (thickness, about 15 nm) beneath an extremely thin transferred lubricant-film. To reduce the bearing wear, the pre-formation of a thick Cr2O3 layer, which restrained metal-to-metal adhesion, seemed to be effective, because the untreated bearing had an extremely thin native Cr2O3 layer (about 2.5 nm). The purpose of this study is to evaluate the Cr2O3 layer chemically formed on the SUS440C ball. These results showed that a considerably thick Cr2O3 layer on a SUS440C surface was successfully formed by heat treatment at a low concentration of oxygen. Friction and wear of the Cr2O3 layer chemically formed was found to be better than that of the untreated ball in LN2.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
