Abstract:
The present invention relates to lubricant compositions and can be used for treatment of friction units in different machines and mechanisms in manufacturing processes, the purpose of which is modification of friction surfaces. The basis of the invention is the improvement of lubricant composition, in which as the consequence of the additional use of thickener and wax, the viscosity of lubricant composition sufficient for conversation of uniform distribution of solid component in lubricant composition in broad temperature range is provided; and at the expense of that, the possibility of conservation of lubricant composition in any packaging and bulks, which are usable even under operating conditions of machines and mechanisms, is reached. The lubricant composition acquires the state of gel, that is convenient to put on any friction surface, to deposit on a zone of friction of any friction units. The lubricant composition ensures the receiving of engineering results similar to those, which solid components exhibit using fine-dispersed powder on basis of natural minerals from flaky silicates series and at the same time the sedimentation properties of lubricant composition permit its continuous conservation in broad temperature range without variation of lubrication and modification properties.

The disclosure relates to improved gel/grease compositions as well as grease compositions capable of imparting improved corrosion resistance. The grease includes a silica/silicate mixture that can impart a relatively high pH and corrosion resistant properties to the grease.
Abstract:
A lubricating composition comprising a base oil of mineral and/or synthetic origin in combination with a friction-reducing additive combination comprising molybdenum disulphide, zinc naphthenate and one or more metal dithiophosphates, and optionally one or more metal dithiocarbamates. A lubricating grease comprising such a composition in combination with a thickener, which may be a urea compound, a simple lithium soap or a lithium complex, is particularly suitable for lubricating constant velocity joints such as constant velocity ball joints.
Abstract:
A solid film lubricant system for protecting metal wear interfaces subject to high temperatures and wet lubrications, comprising an oil-attracting solid lubricant mixture (A) with at least two elements (A1, A2, A3) selected from the group of graphite, MoS2 and BN; a support (B) (i.e., hard lands or hard sublayer) for the mixture to loads of at least 10 psi at temperatures of 600-800 DEG F while being thermally stable; a thermally stable thermoset polymer matrix adhering the mixture to the support or the wear surface, the polymer having inherent hydrocarbon chemical attraction to form a tenacious oil film of the lubricating oil on the wearing surfaces, such as cylinder bore surfaces of a cylinder block of an internal combustion engine.
Abstract:
Iron-based metallurgical powder compositions are produced by mixing iron-based powder with an improved binder/lubricant that comprises dibasic organic acid and one or more additional components such as solid polyethers, liquid polyethers, and acrylic resin. These novel binder/lubricants impart one or more enhanced green properties to the powder compositions and reduce the ejection force required to remove the compositions from molds and dies.
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 mu m. Lubricants are suitable for most applications, but are especially useful for conditions of high temperature and pressure.
Abstract:
A lubricating composition with a solid friction modificator consists of an oil base and a highly-dispersed carbon addition. The addition represents in itself clustered carbon with the size of clusters of 1-10 nm and contains 2.0-99.0 % by weight of non-abrasive diamond and 1.0-98.0 % of graphite. The ratio of the components in per cent by weight is as follows: clustered carbon 0.01-1.0; oil base the balance.
Abstract:
The title lubricant composition comprises a base oil or base grease and a specified amount of a heat insulating agent comprising (A) an inorganic compound undergoing endothermic melting at temperatures of 1200 DEG C or below and (B) an inorganic powder which neither melts nor decomposes at temperatures of 1200 DEG C or below and which has a thermal conductivity of 0.01 cal/cm.s. DEG C or less and a friction coefficient of 0.7 or less at room temperature added alone or as a combination. This lubricant composition has an excellent heat-insulating effect and is effective in preventing occurrence of thermal crown of working rolls.
Abstract:
A wax-based lubricant compounded for use as a bullet lubricant but also useful as an additive to greases and oils for general lubricating usage. The lubricant comprises a combination of petroleum and silicone oil metallic soap greases, beeswax and graphite and molybdenum disulfide.
