Wear-resistant sintered ferrous alloy and method of producing same |
(57) A sintered ferrous alloy high in wear resistance and suitable for parts subjected
to rubbing friction such as rocker arm tips. The alloy is produced by compacting and
sintering a powder mixture of 16-50 parts by weight of a Fe-Cr-B alloy powder, which
contains 10-35% of Cr and 1.0-2.5% of B, 1.0-3.5 parts by weight of graphite powder
and 46.5-83 parts by weight of either a Fe-P alloy powder or a mixture of a Fe-P alloy
powder and an iron powder. The powder mixture is prepared so as to contain 0.2-1.0%
by weight of P.
