Abstract:
There is provided a resin composition for a machinable liner of a sliding member. An ultraviolet curable resin composition for a self-lubricating liner contains a (meth)acrylate compound having an isocyanuric acid ring represented by the following formula and PTFE as a solid lubricant. In the formula (1), X is a group which contains an acryloyl group and is composed only of C, H, and O. Y and Z are groups each composed only of C, H, and O. PTFE is contained in an amount of 10 to 50% by weight with respect to a total amount of the ultraviolet curable resin composition. The ultraviolet curable resin composition is suitable for a self-lubricating liner 24 of a spherical bearing 20 having an outer race 22 and an inner race 26.
Abstract:
There is provided an antioxidant agent capable of preventing scale from being produced on the surface of a heated metallic starting material more effectively than the conventional antioxidant agent. The antioxidant agent according to the present invention contains a plurality of glass frits having different softening points and an inorganic compound having a melting point not higher than 600°C. The inorganic compound mainly softens in the low-temperature range of about 600°C. The plurality of glass frits mainly soften in the low-temperature range of about 600 to 1300°C. Therefore, the antioxidant agent covers the surface of metallic starting material in a broad temperature range, oxidizes the surface of metallic starting material, and prevents the production of scale.

Abstract:
A method to make a graphite block of any desired size and with over 99% carbon purity and high density is provided. The graphite block is obtained by mixing graphite flakes of any size with graphene oxide sheets and subjecting the mixture to elevated temperature and pressure. With this method large graphite blocks can be obtained economically and fast. The graphite blocks of this invention have superlubricity characters.

A friction material composition may include an abrasive, a filler, a binder, and a spherical molybdenum disulfide powder. The spherical molybdenum disulfide powder is made up of molybdenum disulfide sub-particles that are agglomerated together to form individual, substantially spherically-shaped agglomerated particles of at least about 90% by weight molybdenum disulfide.
Abstract:
Provided is a method for producing a seamless tube, in which after a starting material to be extruded has been heated to a heating temperature T [° C.] satisfying the relationship of Formula (1) or Formula (2) depending on the outside diameter d0 [mm] thereof, the starting material is hot extruded by providing a solid lubricating glass between the starting material to be extruded and a die, whereby a transverse flaw on the outer surface in the top portion of tube can be prevented when hot extrusion is performed by using a starting material for extrusion having low deformability at high temperatures.
