Abstract

The present invention provides a sliding member having hardness suitable for bearing a high load environment and excellent in wear resistance. In this sliding member, the surface of the sliding layer for supporting the sliding object to be slidable is subjected to shot blasting so that the surface of the sliding layer forms a sliding surface having a concave-convex shape, and the arithmetic mean deviation of the profile of the sliding surface is (Ra) is greater than 0 μm and less than 2.0 μm, the ten-point height of microscopic unevenness (Rz) is greater than 0 μm and less than 7.5 μm, and the surface hardness (Hv) is 150-250.

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...
