A slide member includes a substrate that is made of a metal material and has a sliding surface with a plurality of microdimples formed therein. Each of the microdimple has a circular opening, the microdimples are arranged in regular intervals in a hexagonal close-packed configuration, and the area ratio of the openings of all the microdimples to the entire sliding surface is in the range of 50 to 80%.

Slide member and method for the production thereof

Disclosed are slide parts, comprising one part made of an aluminium alloy having an Alumite layer formed on the slide surface thereof and the other part made of an aluminium alloy having a Fe-series wet-plated layer formed on the slide surface thereof, which is to be in contact with and slide on the slide surface of the former alloy part; and a method of the manufacture of the slide parts. The slide parts are lightweight and are excellent in abrasion-resistance and baking-resistance. The clearance variation by temperature is little, and the slide parts are suitable for use as reciprocating slide parts.
