Abstract

Provided is a sliding member which has a hardness suitable for use under high-load conditions and which exhibits excellent abrasion resistance. A sliding member obtained by: shot-blasting the surface of a sliding layer, which is to support slidably an object to be slid; and then processing the resulting surface to form a sliding surface which has protrusions and recesses and which exhibits an arithmetic average roughness (Ra) of more than 0 to 2.0[mu]m, a ten-point average roughness (Rz) of more than 0 to 7.5[mu]m, and a surface hardness (Hv) of 150 to 250.

Description

technical field [0001] The present invention relates to a sliding member for slidably supporting a sliding object. Background technique [0002] Generally, in order to reduce friction, the sliding surface is desirably smooth. However, when the sliding surface is made smooth, although the frictional resistance can be suppressed low, the sliding surface will generate some heat, and therefore, there may be a problem caused by so-called burning. To fix (Japanese: condense). Therefore, the sliding surface is required to have an appropriate surface roughness. [0003] Conventionally, the technique of forming recesses by shot blasting the sliding surface is known, and a technique of forming an oil reservoir on the sliding surface of a sliding member by shot blasting is known (for example, refer to Patent Document 1). [0004] Patent Document 1: Japanese Patent No. 4848821 Contents of the invention [0005] The problem to be solved by the invention [0006] By subjecting the...
