    Abstract: Thermal spray coatings are described herein. The coatings include at least one base material having a thickness. Within at least a portion of the thickness is a dispersion of solid lubricant particles. The thermal spray coatings may be applied to at least a portion of a component that has a mating surface with another component. The mating surface may cause the thermal spray coating to wear down and become thinner. As the coating becomes thinner, particles of solid lubricant entrapped deeper within in the base material become exposed and impart friction reducing properties to the component.

    Abstract: Corrosion by ammonia/amine salts in hydrocarbon streams such as distillation overhead streams that contain a mineral acid and water can be prevented, avoided or minimized by adding certain strong amines to the streams. The amines have a pKa between about 10.5 to about 12 and include, but are not necessarily limited to, dimethylamine, diethylamine, dipropylamine, diisopropyl-amine, di-n-butylamine, diisobutylamine, di-sec-butylamine, di-tert-butylamine, pyrrolidine, piperidine, and combinations thereof. If the hydrocarbon stream further includes a nitrogen-containing compound such as ammonia, a tramp and/or a residual amine which can form a corrosive salt with the mineral acid, then the added amine is a stronger base than the tramp or residual amine, if present. The amount of added amine is greater than total amount of nitrogen-containing compound, so that any corrosive salts formed are less corrosive than the salts that would otherwise form from the ammonia and/or tramp amine.

The invention provides for grease compositions comprising (1) base oil (which can be mineral, vegetable, synthetic or combinations thereof), (2) at least one grease thickener (selected from calcium sulfonates or lithium-based soaps), and (3) water as major components. The invention also provides a method for the preparation of the grease composition and a method for lubrication of bearings, gears, surfaces and other lubricated components comprising use of the grease composition of the present invention. The grease compositions of this invention display excellent fire resistance properties and still have outstanding physical and performance characteristics for applications where temperatures and loads are high, shock loading is significant and in the presence of significant amounts of water.

  • Patent number: 7910525
    Abstract: The present invention provides a grease composition capable of effectively preventing a rolling surface of a bearing from having hydrogen brittleness-caused peeling, a grease-enclosed bearing in which the grease composition is enclosed, and a rotation-transmitting apparatus with a built-in one-way clutch in which the grease composition is enclosed at a sliding portion. The grease composition contains a base grease consisting of a base oil and a thickener; and an additive added to the base grease. The grease composition prevents a frictional wear surface of the sliding portion or a newly generated surface consisting of iron or the like exposed owing to wear from being peeled owing to hydrogen brittleness. The additive contains a bismuth-based additive or a magnesium-based additive. The bismuth-based additive consists of at least one of inorganic bismuth and organic bismuth not containing a sulfur component. The magnesium-based additive consists of at least one of inorganic magnesium and organic magnesium.

  • Publication number: 20110048809
    Abstract: The present disclosure relates to greases containing metal sulfonate thickeners. In one example the thickener may be a calcium sulfonate thickener. In other examples grease may contain a combination of a metal sulfonate thickener and another thickener, such as a metal complex soap grease, detergent, or non-soap thickener. The grease may be formulated to meet specific performance criteria relevant to lubrication of a roller cone drill bit in downhole conditions. The disclosure also relates to a roller cone drill bit containing a grease of the disclosure.
