A slide member which is excellent in the initial running-in property and can provide an excellent sliding property even under a strict sliding condition and, in particular, a slide member with a solid lubrication coating film which is excellent not only in the friction property but also in the wear
A slide member which is excellent in the initial running-in property and can provide an excellent sliding property even under a strict sliding condition and, in particular, a slide member with a solid lubrication coating film which is excellent not only in the friction property but also in the wear resistance under the fluid lubrication, boundary lubrication and dry lubrication conditions. The slide member includes a solid lubrication coating film on a flat-plate-shaped base member, characterized in that, in the surface of the slide member, there are formed a plurality of concentrical grooves extending in the peripheral direction of the slide member surface, and, between the mutually adjoining ones of the grooves, there are formed ridge portions respectively.
