ABSTRACT:
An iron-based anti-wear sintered alloy member containing at least 1.5 weight % C, 0.5 to 3.5 weight % P, and one or both of Mo and W in an amount of 0.5 to 3.0 weight % in terms of Mo (the conversion rate of W being 0.5) in addition to iron and having a phosphatic film formed at sliding contact portions. In addition to the above-described elements, one or both of Ni and Cu may be incorporated in an amount of 0.5 to 5.0 weight % in terms of Ni (the conversion rate of Cu being 0.5), of 0.3 to less than 8.0 weight % of Cr may be incorporated, or one or both of Ni and Cu may be incorporated in an amount of 0.3 to 0.7 weight % in terms of Ni together with 0.3 to 0.7 weight % of Cr.
