Abstract:
The provided sliding member has both excellent wear resistance and excellent coating adhesion even under harsh sliding conditions. The disclosed sliding member ( 100 ) is used in the presence of a lubricating oil and includes a base member ( 10 ), a metal intermediate layer ( 12 ) formed on the sliding surface ( 10 A) side of the base member, a layered carbon coating ( 18 ) formed on the metal intermediate layer and having a first carbon coating ( 14 ) and a second carbon coating ( 16 ) layered alternately therein, and a hard carbon coating ( 20 ) formed on the layered carbon coating. Under bright-field observation with a transmission electron microscope, an image of the first carbon coating ( 14 ) is brighter than an image of the second carbon coating ( 16 ). Furthermore, 10 nm<T 2 ≤1000 nm and 0.010≤T 1 /T 2 ≤0.60, where T 1  and T 2  are the thicknesses of the first and second carbon coatings ( 14, 16 ).

Claim (Index 2):
The sliding member of  claim 1 , comprising a thin metal coating having a thickness of 100 nm or less between the first carbon coating and the second carbon coating that are adjacent in the layered carbon coating.
