Abstract:
The invention relates to thermally conductive greases that may contain carrier oil(s), dispersant(s), and thermally conductive particles, wherein the thermally conductive particles are a mixture of at least three distributions of thermally conductive particles, each of the at least three distributions of thermally conductive particles having an average (D 50 ) particle size which differs from the other average particle sizes by at least a factor of five. The thermally conductive greases of the invention exhibit desirable rheological behavior during installation/ application and during use of devices involving these materials.

Abstract:
The coating comprises a solid matrix adhering to the substrate in which are dispersed particles of solid lubricants from at least two classes which are selected to exert a synergistic effect between themselves and with the constituents of the matrix. Protection against corrosion and against galling of the threadings of threaded elements used in h drocarbon wells.
Abstract:
A composition and method for providing a wear-resistant and fuel-saving coating on metals, particularly metal surfaces within internal combustion engines. A source of ammonium ions, an alkali metal in an aqueous medium, and the coating metal to be applied to the surface are combined to produce an electrolyte solution comprising a complex ion mixture. The electrolyte solution can be used to deposit the coating metal on conductive substrates. The coating metal may comprise phosphorus, sulfur, carbon, bismuth, boron, silicon, and combinations thereof. The electrolyte solution can be dehydrated in a hydrocarbon medium, thus providing novel materials for use as lubricating oil additives and as fuel additives. These new surfaces may significantly reduce coefficient of friction, smooth the flame front, reduce corrosion, enhance fuel economy, and reduce hydrocarbon emissions when used in internal combustion engines.
