Abstract:
PROBLEM TO BE SOLVED: To provide dry film lubricant coatings by using a silicone resin binder, either as an aqueous emulsion or in a solvent-based system, to fix an alkaline earth metal fluoride to a substrate.SOLUTION: The compositions used to apply the coatings may also include relatively minor amounts of xylene, ammonium benzoate, a wetting agent, and/or a porosity-inducing agent, although none of those additives remains in the cured coating. Multi-layer dry film lubricant coatings are also disclosed, with the multi-layer coating having a basecoat layer as described above, and a topcoat layer made of a layer-lattice solid such as graphite or molybdenum disulfide, and a silicone resin, aluminum phosphate or an alkali metal silicate binder.
Abstract:
PROBLEM TO BE SOLVED: To provide a functionalized nanosphere lubricant which can be used for reducing friction or wear between all kinds of movable parts. SOLUTION: A method for manufacturing the lubricant is disclosed. This method includes provision of rigid nanospheres with a size of less than about 500 nanometers. The method further includes exposure of the nanospheres to radiant energy in order to at least partially bind a functional chemical on the surface of the nanospheres. COPYRIGHT: (C)2009,JPO&INPIT

PCT No. PCT/DE96/00344 Sec. 371 Date Aug. 25, 1997 Sec. 102(e) Date Aug. 25, 1997 PCT Filed Feb. 23, 1996 PCT Pub. No. WO96/26793 PCT Pub. Date Sep. 6, 1996In accordance with the method according to the invention, for the production of the plastics overlay, first of all a paste is made of a plastics dispersion and fillers. This paste is free of organic solvents and is applied to a sintered porous metal layer. The multilayer material thus produced is then sintered. Since the use of organic solvents is dispensed with, health risks and the risk of fire are reduced. Moreover, the composite materials produced according to the invention exhibit excellent cavitation resistance. In addition to conventional lubricant-free applications, such as bearings, these composite materials may consequently be used in particular in gear pumps and shock absorbers.
Abstract:
PROBLEM TO BE SOLVED: To provide a screw joint for an oil well pipe which exerts sufficient leakage resistance and seizure resistance even under non dope in addition to green dope. SOLUTION: The screw joint for steel pipe is composed of a pin 1 and a box 2 respectively contains contact surfaces having screw parts (1a, 2a) and metal contact parts (1b, 2b) without a screw. Sn-Bi alloy plating or Cu-Sn-Bi alloy plating is formed on at least one contact surface of the pin 1 and box 2. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
A powdery mold-releasing lubricant according to the present invention uses a powdery mixture of a powdery organic material, which is evaporated or decomposed by heating to generate a gas, and a powdery inorganic material. A gas-solid mixed layer formed with the gas generated from the powdery mixture and the powdery inorganic material is used as a heat-insulating boundary layer. The powdery mold-releasing lubricant is inexpensive and has a superior mold lubricity.
