Title: SINTERED BEARING AND METHOD FOR MANUFACTURING SAME
Abstract:
Provided is a sintered bearing in which the number of coarse pores on the bearing surface is reduced and surface open pores are reduced in size and homogenized. This sintered bearing is manufactured by sintering a compressed powder which uses, as a main powder, a partially diffused alloy powder in which a Cu-Sn alloy powder 13 is adhered to the surface of an iron powder 12 by partial diffusion. The maximum particle size of the partially diffused alloy powder 11 is 106 µm or less, and the maximum particle size of the Cu-Sn alloy powder 13 is 45 µm or less.
