摘要： PURPOSE:To improve the wear resistance and to reduce the attacking action on an opposite material by blending prescribed percentages of Cr, C, P, B, Mo, Mn, Fe, Ni and Cu and by forming a prescribed hardened and tempered structure. CONSTITUTION:The titled sintered material consists of, by weight, 0.5-8% Cr, 2-5% C, 0.02-5% P and/or B, 0.05-3% Mo, 0.05-3% Mn and the balance Fe. The material may further contain 0.1-5% Ni and/or Cu. The material has >=90% density ratio and a hardened or hardened and tempered structure contg. 20-60% by area of a carbide-base hard phase dispersed finely and uniformly in the martensite-base matrix. The sintered material attacks scarcely its opposite material and has superior wear resistance.

摘要： PURPOSE:To provide a titled sintered material which has excellent resistance to wear and scuffing and an extremely low characteristic to attack the mating material by having structure subjected to hardening or the like dispersed finely and uniformly with mainly the hard phase of carbide having a specific area rate mainly in the martensite base of a specifically composed steel material and having a specific density ratio. CONSTITUTION:A titled sintered material consists, by wt%, of 0.5-8% Cr, 2- 5% C, 0.02-5% P, 0.05-3% Mo, 0.05-3% Mn, and 5-20% Cu or/and Sn, consists of the balance Fe and unavoidable impurities and satisfies the following conditions: Said material has the hardened or hardened and tempered structure dispersed finely and uniformly with the hard phase having 20-60% area rate and consisting mainly of carbide of M3C type in the base consisting mainly of martesite (in this case the primary crystals, etc. of Cu and Sn exist by forming a dispersion phase). Said material has >=85% theoretical density ratio. Since said material has the above-described characteristics, the material provides excellent performance for a long period of time when used for a sliding member of an internal-combustion engine used under the severe conditions of high temp. and high surface pressure.

摘要： PURPOSE: To provide an Fe base sintered alloy having excellent anti-wear property and self-lubricity, obtained by uniformly dispersing a specific area ratio of free qraphite and CaF
2 in a steel base material containing C, Si, Cr, P or/and B, CaF
2 respectively in a predetermined ratio.
CONSTITUTION: An Fe base sintered alloy contains, on the basis of wt% 2W8% C, 0.1W5% Si, 4W30% Cr, 0.02W5% P or/and B, 0.05W5% CaF
2 and comprises the ramainder Fe and inevitable impurities. In this case, 2W30% in an area ratio of graphite and CaF
2 are uniformly dispersed in said alloy base material. Because this Fe base sintered alloy has the above aforementioned characteristics, effect as mentioned hereinbelow is developed when said alloy used in praparing the movable valve mechanism member of an internal combustion engine especially applied with high surface pressure and poor in a lubricating state at the start of operation. That is, excellent capacity is stably developed over the extremely long period of time without damaging an opposed member.
