Abstract:
A resin composition which exhibits good sealability while keeping creep deformation to a minimum when brought into sliding contact with a mating member at a high contact pressure of over 10 MPa, and which will not damage a mating member made from an aluminum alloy while sliding in contact with lubricating oil. The resin composition is a pressure-resistant, sliding tetrafluoroethylene resin composition containing 100 parts by volume of a modified tetrafluoroethylene resin in the form of a copolymer of tetrafluoroethylene and partially modified tetrafluoroethylene, 5-40 parts by volume of carbon fiber, and 2-30 parts by volume of calcium sulfate whiskers having a Mohs hardness of 4 or less, and having, at 100° C., a maximum deformation rate in 24 hours, of 15% or less. A seal device to be brought into slide contact with an aluminum metal is molded from such a pressure-resistant, sliding tetrafluoroethylene resin composition.

Abstract:
Forge lubrication processes are disclosed. A solid lubricant (38) sheet is placed between a workpiece (30) and a die (34; 36) in a forging apparatus. Force is applied to the workpiece (30) with the die (34; 36) to plastically deform the workpiece. The solid lubricant sheet (38) decreases the shear factor for the forging system and reduces the incidence of die-locking.
Abstract:
An electric submersible motor is provided that includes a plurality of rotors and bearings mounted on a shaft, and a stator external to said rotors. A running clearance is located between an inner diameter of the stator and external diameter of the rotors, and includes a lubricating oil that includes a base hydrocarbon oil and a plurality of nanoparticles. Also provided is an improved lubricant oil and method of preparation thereof are provided. The lubricant oil includes a hydrocarbon containing base oil and a plurality of nanoparticles. The nanoparticles may be present in an amount up to 30% by volume.
Abstract:
The invention relates to methods for enhancing the lubricity of a surface by forming at least one metal oxide on the surface. In some embodiments, the metal oxide enhances the lubricity, and in other embodiments, the metal oxide works with another lubricant to further enhance lubricity. The wear rate of a metal surface is reduced dramatically when at least one metal oxide is formed on the surface, in some embodiments.
