Abstract:
In cold flow processing of metals, especially steel, coatings of transition metal halogenides, especially FeCl3, have proved suitable because they efficiently counteract cold welding problems. The coatings may be applied in the form of a melt or a saturated or diluted, aqueous solution of the transition metal halogenide. If a melt is used, it may be mixed with one or more common solid lubricants such as MoS2, graphite, or the like.
Abstract:
The present invention provides lubricant compositions for the powder metallurgical field. The lubricant compositions contain a solid phase lubricant such as graphite, molybdenum disulfide, and polytetrafluoroethylene in combination with a liquid phase lubricant that is a binder for the solid phase lubricant. The binder can be chosen from various classes of compounds including polyethylene glycols, polyethylene glycol esters, partial esters of C3-6 polyhydric alcohols, polyvinyl esters, and polyvinyl pyrrolidones. The binder is solubilized in an organic solvent.
Abstract:
A solid lubricant additive for resin-bound friction lining mixtures is characterised in that it contains a combination of copper-I-sulphide (Cu2S) with at least another sulphide of molybdenum, zinc, antimony, wolfram, tin and/or titanium.
Abstract:
A rubber or plastic sliding member coated with a material having excellent durability and high slipperiness, wherein the coating material is composed of a solid lubricant such as molybdenum disulfide and a resin matrix comprising a fluoroolefin vinyl ether polymer resin and/or a fluoroolefin vinyl ether/vinyl ester copolymer resin.
Abstract:
A lubricant additive that includes antimony thioantimonate and antimony trioxide in a specified ratio for enhancing the extreme pressure, antiwear, and antiabrasive properties of conventional lubricants as well as for use in lubrication of a wide variety of lubricated contact surfaces.
Abstract:
This invention provides a threaded connection for pipe or tube that has a non-sticky surface and that suppresses the occurrence of rust and exhibits excellent galling resistance and airtightness even in an extremely low temperature environment without using compound grease, a method of producing the same, and a composition for forming a solid lubricating coating on the threaded connection. A solid lubricating coating (24) formed from a composition containing a binder, a fluorine addition agent, a solid lubricant and a rust proof addition agent is coated as a topmost surface treatment coating on a contact surface of at least one of a pin and a box. Even when exposed to an extremely low temperature environment, the solid lubricating coating (24) can maintain adhesiveness and exhibit a lubricating function, can suppress the occurrence of galling of a threaded connection, and can also secure airtightness after fastening.
Abstract:
A coating of a metal sheet or strip comprising a lubricant and a protective base material is provided. The lubricant is contained in the protective base material, and the protective base material is at least in part selectively removable. There is also provided a metal sheet or strip capable of forming, in particular of superplastic forming, and having a coating according to the invention at least partially on one or on both sides of the metal sheet and a method for manufacturing a metal sheet or strip according to the invention comprising the steps of providing a metal sheet or strip capable of forming, in particular of superplastic forming, and applying a coating according to the invention.
Abstract:
A method of coating uses an anti-seizure agent for hot steel working that exhibits excellent wettability and surface film-adherability. 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.
