Abstract
To provide a sliding member which has hardness that is suitable for the circumstance, to which heavy load is applied, and which is excellent in abrasion resistance property. The sliding member contains a sliding layer for slidably supporting a body to be slid, shot blasting being performed on a surface of the sliding layer, and a sliding surface formed on a surface of the sliding layer, the sliding surface having an uneven configuration with arithmetic mean roughness (Ra) of 1.0 μm through 2.5 μm, 10-point average roughness (Rz) of 5.0 μm through 10.0 μm, and surface hardness (Hv) of 220 through 250.
Claims3
A sliding member comprising:
- a sliding surface formed on a surface of a sliding layer which is impact-hardened by a shot-blasting treatment, wherein the surface of the sliding surface has an uneven shape to form an oil reservoir, wherein the sliding surface exhibits arithmetic mean roughness (Ra) in the range of 1.0 μm through 2.5 μm, 10-point average roughness (Rz) in the range of 5.0 μm through 10.0 μm and surface hardness (Hv) in the range of 220 through 250, and the sliding surface slidably supports a body to be slid, and wherein the sliding layer is composed of a copper alloy having a surface hardness (Hv) of 80 through 150 before the shot-blasting treatment.
