Title:
COATED SLIDE MEMBER
Document Type and Number:
WIPO Patent Application WO/2016/042945
Kind Code:
A1
Abstract:
[Problem] To provide a coated slide member which makes polishing of a coating film surface easier in cases where a diamond-like carbon that does not contain hydrogen is formed on the surface of a base material so as to have a thickness of 3 μm or more, and which achieves low friction and wear resistance in an environment where the coated slide member is in contact with a lubricant oil.
[Solution] A coated slide member 10 which is used in an environment where the coated slide member is in contact with a lubricant oil, and which comprises: a base material 12; a first hard carbon layer 14 having a thickness of 3 μm or more, which is formed on the surface of the base material by a vacuum arc method using carbon and is formed of diamond-like carbon that is configured only of carbon and does not substantially contain hydrogen; and a second hard carbon layer 15 which is formed directly on the surface of the first hard carbon layer by a vacuum arc method using carbon and is formed of diamond-like carbon that is configured only of carbon and nitrogen and does not substantially contain hydrogen. The film thickness of the second hard carbon layer is 3-35% of the film thickness of the first hard carbon layer.
