Abstract

See full text

A method for producing an iron-based sintered alloy, which is used in sliding components in pairs and has a composition including, in terms of percent by mass, Ti: 18.4 to 24.6%, Mo: 2.8 to 6.6%, C: 4.7 to 7.0%, Cr: 7.5 to 10.0%, Ni: 4.5 to 6.5%, Co: 1.5 to 4.5%, Al: 0.6 to 1.0%, the balance being Fe and unavoidable impurities, wherein the method is carried out such that the alloy has a structure in which hard particles are dispersed in an island form in a matrix and, while an area ratio thereof is kept constant, a maximum circle equivalent diameter thereof is controlled to a predetermined value of 40 to 10 μm.
