The agent comprises: an inorganic component (first component); sodium hydroxide (second component); water-soluble resins and/or water-soluble surfactants (third component); and water. With the sum of the first component, the second component, and the third component as 100 mass %, the anti-seizure agent contains: 96.5 mass % or more and 99.98 mass % or less of the first component; 0.01 mass % or more and 2.0 mass % or less of the second component; and 0.01 mass % or more and 1.5 mass % or less of the third component, and the inorganic component is one or more selected from a group consisting of Al2O3, SiO2, CaO, B2O3, K2O, and Na2O. A coating layer formed solidly adheres to the steel and does not come off in both cold and hot working.

  • Patent number: 8420581
    Abstract: A lubricating coating which is free from harmful heavy metals is formed on a premium threaded joint for pipes constituted by a pin and a box each having a contact surface comprising a threaded portion and an unthreaded metal contact portion (a sealing surface and shoulder) in order to provide the joint with galling resistance, gas-tightness, and anticorrosive properties such that the unthreaded metal contact portion is prevented from yielding even when the joint is made up with a high torque. The lubricating coating comprises one or both of a rosin and calcium fluoride; metal soap; wax; and a basic metal salt of an aromatic organic acid, and preferably it further includes a lubricating powder, magnesium carbonate, and/or a carbohydrate, particularly a cyclodextrin.

  • Patent number: 8420580
    Abstract: A sliding resin composition is provided which hardly seizes by decreasing oil repellency of PTFE to prevent discharging of lubricating oil from sliding surface. That is, by using resin composition 1 where particles of PTFE 3 in the surface of which inorganic compound 4 having oil-absorptivity is embedded are dispersed in synthetic resin 2, the inorganic compound 4 having oil-absorptivity absorbs and retains lubricating oil, and oil repellency of PTFE 3 on the sliding surface can be decreased. Thus, discharging of the lubricating oil from the sliding surface can be inhibited and resin composition 1 hardly seizes.

  • Patent number: 8410029
    Abstract: The present invention provides a surface-oxide abrasion-resistant lubricant coating that can maintain high lubricity for a long time without wear of a base material and a coating or damage to an object to be contacted by a simpler method and with less expensive material. A mixed fluid of a compressed gas and fine-particle powders of two soft metals having lower hardness and lower melting point than the base material of a sliding contact portion is ejected onto a surface of the sliding contact portion. The fine-particle powders of the soft metals are made to react with oxygen in the compressed gas at the surface of the sliding contact portion to form a metal-oxide film with high melting point composed of metal oxides of the two soft metals, one of the metal oxides having higher hardness than the other. This metal-oxide film with high melting point includes a coating having a thickness of 0.

    Abstract: The present invention provides a lubricating oil composition for reducing a friction coefficient adjacent to the surface of being subjected to lubrication. In particular, the present invention provides nanoporous particles capable of being dispersed in a lubricating oil composition comprising base oil having a lubricant viscosity. Since the nanoporous particles having nano-sized, oil soluble pores according to the present invention reduces a friction coefficient, and in the long term, gradually releases an effective ingredient, the lubricating oil composition comprising the same of the present invention can act as a reducing agent for reducing friction for a long period of time, and thereby, exhibit excellent lubricant effects.
