Abstract
Official abstract text for this publication.
A sliding member which has a hardness suitable for use under heavy-load conditions and which exhibits excellent abrasion resistance property. A sliding surface is formed on a surface of a sliding layer that slidably supports an object to be slid. The sliding surface is then shot-blasted and is formed to have an uneven shape exhibiting an arithmetic average roughness (Ra) of more than 0 to 2.0 μm, a ten-point average roughness (Rz) of more than 0 to 7.5 μm, and a surface hardness (Hv) of 150 to 250.
First claim
Opening claim text (preview).
1 . A sliding member comprising a sliding surface is-formed on a surface of a sliding layer to-which has been subjected to a shot-blasting treatment, wherein a surface of the sliding surface has an uneven shape exhibiting arithmetic average roughness (Ra) of more than 0 μm and 2.0 μm or less, ten-point average roughness (Rz) of more than 0 μm and 7.5 μm or less and surface hardness (Hv) of 150-250, and the sliding surface slidably supports an object to be slid. 2 . The sliding member according to claim 1 , wherein in the shot-blasting treatment, a grinding material composed of an iron-based metal material having a spherical shape exhibiting a particle size of 180-300 μm and a surface hardness (Hv) of 280-600 is used, a spray distance thereof is 50 mm or more and 150 mm or less and a grinding time therefore is 5 seconds or more and 30 seconds or less. 3 . The sliding member according to claim 1 , wherein said sliding layer is composed of a copper alloy having a surface hardness (Hv) of 80-150 before the shot-blasting treatment. 4 . The sliding member according to claim 1 , wherein a thickness of said sliding layer is more than 0 mm and 1.5 mm or less.
