In a sliding member, a coating layer 2 containing a binder resin and a solid lubricant is formed on a surface of a bearing alloy layer or a base material 1. A flaky metal 3 is added as a thermally conductive filler to the coating layer 2. The flaky metal 3 are close to one another, or in contact with one another to form a heat transfer path which transfers heat off the surface of the coating layer 2 to the base material 1. The thermal conductivity of the coating layer 2 is set to 0.4 W/m Ò K or more, so that the heat generated on the surface of the coating layer 2 due to rotation of a mating shaft is easily released to a bearing alloy layer 1 side, the reduction in strength of the coating layer 2 can be suppressed, and conformability and anti-seizing property are enhanced. As an alternative to the flaky metal potassium titanate whiskers or carbon black can be added to the coating layer. In a further alternative two or more of the flaky metal, potassium titanate and the carbon black can be added to the coating layer. The flaky metal is preferably present in 5-20% volume, the potassium titanate in 1-5% volume and the carbon black in 1-10% volume. Where two or more are present the total content is 25% volume or less. |
