Abstract
It is possible to provide an iron-based sintered sliding material excellent in the sliding performance. Provided is an iron-based sintered sliding material including, a base containing, by mass, 3 to 15% of S, 0.2 to 6% in a total amount of at least one selected from the group consisting of Cr, Ca, V, Ti, and Mg, and a remainder of Fe and inevitable impurities, sulfide particles containing at least one selected from the group consisting of Cr, Ca, V, Ti, and Mg being dispersed in the base, and pores.
Claims19
An iron-based sintered sliding material, comprising:
- a base containing, by mass, 3 to 15% of S, 0.2 to 6% in a total amount of at least one selected from the group consisting of Cr, Ca, V, Ti, and Mg, and a remainder of Fe and inevitable impurities, sulfide particles containing at least one selected from the group consisting of Cr, Ca, V, Ti, and Mg being dispersed in the base;
- and
- pores.
An iron-based sintered sliding material, comprising:
- a metal sulfide having not less than 20% of an area ratio, wherein
- a number of particles of the metal sulfide is not less than 8.0×1010 particles/m2 per unit area.
An iron-based sintered sliding material, comprising:
- a metal sulfide having not less than 20% of an area ratio, wherein
- a number of the particles of the metal sulfide, each particle having a particle size of not more than 1 micrometer, accounts for not less than 40% of a total number of all of the particles of the metal sulfide.
