Abstract:
A sliding member (1) includes: a back metal layer (2); optionally a porous metal layer (6); and a sliding layer (3). The sliding layer includes: a synthetic resin matrix (4); graphite particles (5) dispersed in the matrix (4) having a volume ratio of 5-50 % of the sliding layer; optionally 1-20 volume % of one or more solid lubricants; and optionally 1-10 volume % of one or more fillers. The graphite particles are composed of spheroidal particle (51) and flake-like particles (52) having a volume ratio of 10-40 % of total graphite particles (5). The spheroidal particles have a cross-sectional structure with a plurality of AB planes laminated along a curved surface. The flake-like particles have a cross-sectional structure with the AB planes laminated in a thickness direction. The spheroidal particles have an average particle size of 3-50 µm, and the flake-like particles have that of 1-25 µm.
Abstract:
A water based dispersion that includes lubricating nanoparticles. The lubricating nanoparticles can be provided by at least one intercalation nanoparticle of a metal chalcogenide in dispersion with the water base. The at least one intercalation nanoparticle may have a geometry that is fullerene-like, tubular-like structure or be substantially spherical or the intercalation nanoparticles may include particles have each of the aforementioned geometries. The intercalation nanoparticle is surface treated with a dispersant that is water soluble and includes a polar functional group.
Abstract:
Disclosed is a grease composition for a precision instrument comprising a lithium soap grease or a urea grease, and an anti-wear agent, wherein the lithium soap grease and the urea grease are each a grease having no hydroxyl group in a molecule, and the anti-wear agent is contained in an amount of 0.1 to 20% by weight based on the total amount of the grease composition. By the use of the grease composition for a sliding mechanism of a precision instrument such as a watch, an appropriate slip torque can be obtained, and the precision instrument such as a watch can operate stably.
Abstract:
Disclosed herein is a sliding member that has a coating layer serving as a sliding surface thereof so that even when foreign matter enters between the coating layer and a partner member, smoothness between them is maintained to prevent the occurrence of seizing. When the coating layer has an elastic recovery ratio of less than 60%, foreign matter that has entered between the coating layer and the sliding surface of a partner member is efficiently embedded in the coating layer. When the coating layer is formed of a resin composition, the resin composition contains a binder resin, a solid lubricant, and metal particles having a Young's modulus of 10 GPa or more but 100 GPa or less.
Abstract:
The present invention relates to a lubricating composition comprising an anti-wear additive and metal nanoparticles. The lubricating composition according to the invention simultaneously exhibits good stability and also good friction properties which last over time.
