Title:
SLIDING COATING FILM AND SLIDING MEMBER
Document Type and Number:
WIPO Patent Application WO/2022/176113
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a sliding coating film which is capable of suppressing separation phenomenon that is different from detrition due to sliding. The problem is solved by a sliding coating film which is a multilayer film that is obtained by sequentially superposing an adhesive layer, a first carbon layer and a second carbon layer in this order on a metal-based substrate that constitutes a sliding member, wherein: a peak is present between the loss energy of 280 eV and the loss energy of 290 eV in the electron energy loss near edge structures (C-K loss edge ELNES) of the first carbon layer and the second carbon layer as determined by TEM-EELS; and the peak height of the first carbon layer is higher than the peak height of the second carbon layer.
