Patent number: 10495146Abstract: ZnO sputtering is performed while a rolling body is housed in a basket made of a metal wire and is rotated. By setting a ratio of a mesh size of the basket to a diameter of the rolling body in a range of 40 to 95%, fine and uniform ZnO coating can be formed on a surface of the rolling body. By using the rolling body with ZnO coating prepared in this manner in a bearing which is rotated at high speed in a high-load state, a friction coefficient can significantly be lowered in comparison with a case of no coating.Type: GrantFiled: August 25, 2016Date of Patent: December 3, 2019Assignee: NATIONAL INSTITUTE FOR MATERIALS SCIENCEInventors: Masahiro Goto, Michiko Sasaki, Akira Kasahara, Masahiro Tosa
