  • Patent number: 8727622
    Abstract: To provide a sliding member which can control a relationship between dynamic friction force and static friction force, a sliding member 1 constitutes a bearing having a cylindrical shape and its internal circumferential surface is a sliding layer 2 along a shaft. The sliding member 1 is provided a surface of the sliding layer 2 with uneven surface 6. The uneven surface 6 has the line-like projections 6a, vertexes of which are arranged in gridlike fashion, in the embodiment, to prevent an oil film from being formed and to make the dynamic friction force larger and keep the rate of change in the dynamic friction force in relation to the static friction force smaller. The sliding layer is configured so that a porous layer made of alloy material is formed on a surface of a metal substrate and the resin filled into the porous layer is sintered.

  • Patent number: 7255933
    Abstract: A multi-layer sliding part is prepared by a process including mixing 1–50 parts by volume of a Cu-plated solid lubricant powder with 100 parts by volume of a Cu-based alloy powder comprising 5–20 mass % of Sn and a remainder of Cu to form a mixed powder, sintering the mixed powder in a reducing atmosphere to form a sintered mass, pulverizing the sintered mass to form a powder, dispersing the powder formed by pulverizing on a metal backing plate, and sintering the dispersed powder to bond grains of the dispersed powder to each other and to the backing plate. After sintering of the pulverized powder to form bearing metal layer, the bearing metal layer is pressed and densified. After densification, the bearing metal layer is annealed, again pressed, and then coated with a resin having good sliding properties.
