ABSTRACT:
A copper-based sliding member having excellent resistance to corrosion with sulfur and a Vickers hardness of 80 to 150, prepared by bonding to a backing metal layer a sliding layer comprising more than 35% by weight but not more than 43% by weight of Zn, the balance being composed of Cu, by a pressure-bonding method, subjecting the pressure-bonded assembly to diffusion-annealing and subjecting the assembly to work-hardening treatment to allow the sliding layer softened by the diffusion-annealing to have a Vickers hardness to 80 to 150. Said sliding member is excellent in resistance to corrosion with sulfur even under the conditions that a lubricating oil having a high sulfur concentration is used and also excellent in wear resistance.
