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 improve wear resistance, pitting resistance property, scuffing resistance, and breaking-in of the control valve member by constituting a pad forming the sliding part of the control valve member of a powdery sintered material and providing a coating layer such as a cemented layer, a nitriding layer or the like, on the surface of the pad. CONSTITUTION:The pad provided on the sliding part of the control valve is constituted of an iron system powdery sintered material such as a C-Cr-Mn-Si- P(B)-(Mo, W, Nb, Ti, Zr, Ta, V, Ni, Co, Cu, Sn)-Fe alloy or the like. The cemented layer is formed on the surface of the pad, and further a coating layer constituted one or more selected from the group consisting of a nitriding layer, a nitriding reaction layer, a phaphate film and the like, is formed. The above described cemented layer prevents the matrix from softening when the coating layer is formed and secures a suitable hardness. The cemented layer improves the durability of the pad, and the coating layer improves the breaking-in and pitting resistance thereof.

摘要： PURPOSE:To make bonding firm and joining strength uniform when an Al (alloy) member is joined to a sintered Al member by bringing a green compact or a presintered body of Al blended with a proper amount of a specified element into contact with the Al member to be joined, and carrying out sintering. CONSTITUTION:When an Al (alloy) member is joined to a sintered Al alloy member, a green compact or a presintered body is blended with 1-50wt% powder of >=1 kind among Cu, Mg, Sn, Zn and Si as joining accelerating components such as 1-20% Si powder before forming the sintered member. The blended green compact or presintered body is brought into contact with the surface of the Al member to be joined, and sintering is carried out. The joining accelerating component forms a eutectic with Al and becomes a liq. phase at a relatively low temp. during sintering, so sintering is accelerated. The wetting property is improved, and remarkably firm and uniform metallurgical bonding is attained by diffusion.

摘要： PURPOSE:To obtain a sleeve for driving a caterpillar with high durability against abrasion of earth and sand and repeated high load for a long time by combining a surface layer of sintered hard material to disperse particles above MHv 1,000 at an area rate above 15% on a contact face of a steel sleeve with a sprocket. CONSTITUTION:This sleeve is composed of a steel sleeve main body 1 and a surface layer 2 of sintered hard material in which hard particles with hardness above MHv 1,000 are dispersed at an area rate above 15% and the difference of coefficient of thermal expansion with the sleeve main body is within 0.3X10 / deg.C (only in the thermal range of 0-600 deg.C); the surface layer of the said sintered hard material is combined on a partial or the whole surface of the contact part of the sleeve main body with a sprocket for transmitting a drive power. When the hardness of the hard particles is under MHv 1,000 or the dispersion of the hard particles is under 15% area rate, the durability against abrasion of earth, wet sand, and the like is greatly reduced to loose the advantage to prolong the life of the sleeve for driving a caterpillar. When the difference of the thermal expansion coefficient between the sintered hard material and the sleeve main body surpasses 0.3X10 / deg.C, the cooling process after dispersing combination at high temperature and the cementation after the combination, or the contraction difference after hardening, cause cracking.
