Abstract:
Compositions containing a reverse micelle comprising a first compound and a second compound are disclosed, wherein the second compound is configured to change conformation in response to a stimulus, a first conformation selected for formation of the reverse micelle, and a second conformation selected for disruption of the reverse micelle; and wherein the first compound is selected to interact with the first conformation of the second compound to form the reverse micelle.
Abstract:
A die release agent composition is provided that is used by being applied to a die used for the squeeze casting, low-pressure casting, or the like of a metal or a die used for die forging. The die release agent composition includes a mineral oil or a synthetic oil, a solid lubricant, a thermosetting resin, and a polymer compound. The die release agent composition is used by being applied to the inner surface of a die for casting or forging.
Abstract:
An object of the present invention is to provide a sliding member suitable to a soft mating member low in hardness. The present invention relates to a sliding member for sliding with a mating member having a ferrite phase at least on a surface thereof, the sliding member including a coating layer containing a binder resin, molybdenum disulfide, and hard substance particles.
Abstract:
A nanolubricant composition is described where the lubricant composition includes a flowable oil or grease with a multi-component nanoparticle dispersed in the flowable oil or grease. The multi-component nanoparticle includes a first nanoparticle component which effects thermal conductivity at a part interface and a second nanoparticle component which effects shearing at a part interface.
Abstract:
Compositions having a plurality of hard particles and a plurality of lubricant nanoparticles are disclosed. Methods of making and using the compositions are also disclosed.
Abstract:
A tubular threaded element including a dry protective coating. The coating includes a solid matrix adhering to the substrate in which there are dispersed particles of at least one solid lubricant belonging to one and the same class. The solid matrix is lubricating and has a rheological behaviour of plastic or viscoplastic type. The coating protects the threadings of the threaded elements, used for example in hydrocarbon wells, from corrosion and galling.
Abstract:
A lubricating grease composition for extra heavy duty extreme pressure applications comprises a major amount of a synthetic base oil a lithium complex thickener, at least one extreme pressure agent; and at least 5 wt. % of molybdenum disulfide, based on a total weight of the lubricating grease composition.
Abstract:
A composition that includes solid lubricant nanoparticles and an organic medium is disclosed. Also disclosed are nanoparticles that include layered materials. A method of producing a nanoparticle by milling layered materials is provided. Also disclosed is a method of making a lubricant, the method including milling layered materials to form nanoparticles and incorporating the nanoparticles into a base to form a lubricant.
Abstract:
The invention provides a lubricating grease composition with a worked penetration of 400 to 500 for a machine tool equipped with an automatic lubricator, containing a base oil having a kinematic viscosity at 40° C. of 10 to 200 mm2/s and 0.1 to 10 mass % of solid particles insoluble in the base oil. The lubricating grease composition of the invention can be fed using the automatic lubricator attached to the machine tool, and can prevent the stick-slip from occurring on the sliding lubrication portion of the machine tool.
Abstract:
Coating systems which provide corrosion resistance and, optionally, lubrication, for threaded connections are disclosed. The compositions comprise a first coating composition comprising polymer matrices of polyimides or epoxies which are modified with small amounts of a fluorine containing polymer. Also present in the coating compositions are corrosion inhibiting agents and inorganic particles having a mean diameter of between approximately 10 nm and 10 μm. Solid lubricants, which may include at least one of PTFE, HDPE, Graphite, and MoS2, are optionally added to provide the first coating with a low coefficient of friction. The coating systems may further comprise a second coating composition, comprising a solid lubricant dispersed within an epoxy resin and a solvent. The first and second coating compositions are deposited on at least a portion of at least one of the pin and box members of the threaded connections.
