Abstract:
A lubricant composition comprises at least 0.1 % by weight of substantially spherical particles of a hard, abrasion-resistant and fracture-resistant, thermally stable and chemically inert material, and up to 99.9 % by weight of a supporting vehicle. The particles are preferably of silica-alumina ceramic material, and preferably have an average diameter of less than 250 νm. Lubricants are suitable for most applications, but are especially useful for conditions of high temperature and pressure.
Abstract:
A kit and process are provided for working metals, said kit comprising a metal nitride and/or metal carbonitride coated metal working tool and a water soluble metal working fluid, said fluid comprising a relatively large alkoxylated amine, an alkanolamine and an acid-derived compound selected from organic acids, inorganic acids, and salts thereof, and said process comprising contacting a metal workpiece with said metal working tool in the presence of said fluid to effectuate working of said metal.
Abstract:
Verbindungen, erhältlich durch Mischen und/oder, gegebenenfalls gleichzeitiges, Mahlen eines vorzugsweise flüssigen Phosphats und einer Festschmierstoffkomponente, wie Graphit, eignen sich vorzüglich als Additive für Schmierstoffe.
Abstract:
Organic peroxide curable polydiorganosiloxane compositions having improved release from metal molds upon curing are disclosed. In addition to the conventional high molecular weight polydiorganosiloxane gum, reinforcing filler, structure control additives, and curing agent, the improved compositions of this invention contain from 0.05 to 3 parts by weight of a polydiorganosiloxane fluid having methyl groups and carboxyfunctional groups as substituents.
Abstract:
The present invention describes a lubricant additive composition characterised in that the additive composition comprises a first metal component and nanoparticles including a second metal component. Furthermore the present invention describes a lubricant composition and a grease composition comprising the present additive composition.
Abstract:
Composite particles and a method of forming composite particles are described. The composite particles comprise at least one inorganic nanoparticle covalently bound to at least one inorganic microparticle with a linking compound. Lubricant compositions and sprayable dispersion compositions comprising composite particles are also described.
Abstract:
The present invention describes use of use of a metal compound to control the quality of a functional fluid. Additionally, the present invention concerns a method for controlling the quality of a functional fluid comprising the steps of: adding a metal compound to a component of a lubricant; mixing the component with a base oil; measuring the concentration of the metal compound in the functional fluid; and comparing the expected concentration of the metal compound with the measured concentration.
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.
