Abstract
A sliding member of the present invention includes a resin overlay layer containing an additive, in which the additive contains an oleophobic resin made of a fluorine resin and/or a silicon resin, and an appropriate amount of the oleophobic resin is uniformly dispersed on a sliding surface of the resin overlay layer. According to the sliding member, oil repellency can be imparted to the sliding surface of the resin overlay layer.
Claims6
A sliding member comprising a resin overlay layer containing an additive,
- wherein the additive contains an oleophobic resin made of a fluorine resin and/or a silicon resin, and
- the oleophobic resin is dispersed on a sliding surface of the resin overlay layer under the following conditions:
- U=s/(S*0.2)≤1
- where 6%≤S≤30%,
- s is a standard deviation of areas of Voronoi polygons, and
- S is an area ratio of an area where the oleophobic resin is exposed.
