Abstract: With the objectives of alleviating the property of attacking on the mating member by scratching-off of local agglutinates on the sliding contact surface, achieving improved wear resistance, and achieving improved seizure resistance through restraint of frictional heat generation by a hard phase, a copper based sintered contact material contains shock-resistant ceramics in an amount of 0.05 to less than 0.5 wt % as non-metallic particles composed of one or more substances selected from pulverized oxides, carbides and nitrides. The shock-resistant ceramics are comprised of SiO2 and/or two or more substances selected from SiO2, Al2O3, LiO2, TiO2 and MgO.

Abstract: A contact material which provides improved wear resistance as well as reduced adhesion utilizing the features of an intermetallic compound having an ordered phase, with the intention of (i) improving the seizure resistance and/or wear resistance of an implement bearing which slides under low-speed, high-surface-pressure conditions and is susceptible to lubricant starvation; (ii) preventing abnormal noises; and (iii) achieving prolonged greasing intervals. The contact material contains 10% by volume or more a metallic alloy phase having such a composition range that causes an order-disorder transition. The metallic alloy phase is a Fe base alloy phase containing one or more elements selected from the group consisting of Al, Si, Co and Ni.

Abstract: In a copper-based sintering sliding material, to reduce attacking power to the counter material by expressing an ability to scrape a local adhered object on the sliding surface, improve abrasion resistance of the material, and suppress the abrasive heat generation due to the hard phase, thereby improving the seizure limit, heat shock resistant ceramics comprising two or more selected from SiO2 and/or SiO2, Al2O3, LiO2, TiO2 and MgO are dispersed in an amount of 0.05 to 0.5% by weight or less, as nonmetallic particles comprising one or more kind(s) selected from finely grinded oxides, carbides and nitrides.

Abstract: There is provided a sintered material of which dimensional accuracy has been increased by improving the sinterability of Cu—Al based sintered material. More specifically, there are provided a sintered material and a composite sintered contact component, which are excellent in strength, wear resistance, seizure resistance and corrosion resistance. The sintered material is a Cu—Al based sintered material containing at least 1 to 12 wt % Sn and 2 to 14 wt % Al, and the composite sintered contact component is formed by sinter-bonding this sintered material to a metal backing.

Abstract: There are disclosed copper-base and/or iron-base contact materials which contain a Pb intermetallic compound dispersedly precipitated therein and which have highly improved sliding properties. Double layered contact elements improved in oil impregnation and lubricity are formed by sinter bonding the above contact materials to an iron-base metal backing, respectively. Economical producing methods for such double layered contact materials are also disclosed. In the copper-base and/or iron-base contact materials, one or more kinds of Pb intermetallic compounds are dispersedly precipitated.

Abstract: A self-lubricating sintered sliding member and its producing method, the member having excellent seizing resistance and wear resistance even in offset load and high load applications.The self-lubricating sintered sliding member is composed of an iron-family metal substrate and a sintered contact layer that is formed on a sliding side of the iron-family metal substrate and made from a sintered contact material containing an iron-family material. The sintered contact layer has, on a surface thereof, protrusions formed from solid lubricant particles including graphite. A solid lubricant layer is laid over the surface of the sintered contact layer where the protrusions are formed.
