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.
