Abstract
A slide member is provided with a base material, a plated slide layer and an intermediate plated layer. The plated slide layer contains a solid lubricant. The intermediate plated layer is disposed between the base material and the plated slide layer, the intermediate plated layer increasing cohesion of the base material and the plated slide layer. The plated slide layer has a content of the solid lubricant in a range from 30 to 70 vol %, inclusive.
Claims14
A slide member comprising:
- a base material;
- an intermediate plated layer disposed on a first outer surface of the base material between the base material and the plated slide layer;
- and
- a plated slide layer disposed on a second outer surface of the intermediate plated layer, the plated slide layer containing a first solid lubricant,
- the plated slide layer having a thickness of 1 μm to 15 μm and having a content of the first solid lubricant in a range from 40.0 vol % to 50.0 vol %, inclusive, of an entirety of the plated slide layer,
- the intermediate plated layer having a thickness of 1 μm to 5 μm and containing a second solid lubricant and at least one metal selected from the group consisting of nickel, copper, tin and zinc,
- a content in vol % of the second solid lubricant in the intermediate plated layer being less than the content of the first solid lubricant in the plated slide layer and less than or equal to 30 vol % of an entirety of the intermediate plated layer,
- the plated slide layer being an outermost layer of the slide member and having a substantially uniform dispersion of the first solid lubricant throughout an entirety of the plated slide layer,
- the intermediate plated layer being in direct physical contact with the base material,
- the base material consisting of at least one selected from the group consisting of:
- iron, stainless steel, aluminum, titanium, copper, brass, and alloys thereof, and
- a total thickness of the plated slide layer and the intermediate plated layer ranging from 2 μm to 20 μm.
