An anti-friction lacquer has a resin matrix of a polymer and functional fillers containing mixed-phase oxides having a specified grinding hardness and proportion and optionally contain further functional fillers. A sliding element is also disclosed having a metallic substrate layer and a coating applied to the substrate that is made of at least in part of the anti-friction.

In relation to the NAO friction material free of copper component, this invention is to provide the friction material that prevents the occurrence of metal catch while securing sufficient wear resistance. In the friction material manufactured by forming the NAO friction material composition which is free of copper component, the above-described friction material composition does not contain metal simple substance or alloy and contains, as the lubricant, metal sulfide having 600 centigrade or higher decomposition temperature to be decomposed into metal and sulfur, 2.0-5.0 weight % of graphite and a zirconium silicate as an abrasive material. Here, the metal sulfide is not a molybdenum disulfide or a tungsten disulfide. Especially, the content of the metal sulfide is preferably 0.5-2.0 weight % relative to the total amount of the friction material composition.

In an embodiment, the silasesquioxane has the chemical formula [RSiO3/2].sub.n with: n=6, 8, 10, 12; where R independently of one another=alkyl (C1-C20), cycloalkyl (C3-C20), alkenyl (C2-C20), cycloalkenyl (C5-C20), alkynyl (C2-C20), cycloalkynyl (C5-C20), aryl (C6-C18) or heteroaryl group, oxy, hydroxy, alkoxy (C4-C10), oxirane polymer (degree of polymerization with 4 to 20 repeat units), carboxy, silyl, alkylsilyl, alkoxysilyl, siloxy, alkylsiloxy, alkoxysiloxy, silylalkyl, alkoxysilylalkyl, alkylsilylalkyl, halogen, epoxy (C2-C20), ester, aryl ether, fluoroalkyl, blocked isocyanate, acrylate, methacrylate, mercapto, nitrile, amine, and/or phosphine group, each substituted or unsubstituted.

A method for performing a coiled-tubing process, the method having the steps: performing a coiled-tubing process using a fluid-lubricant composition that includes a sulfur-containing compound, and introducing the fluid-lubricant composition into a subterranean wellbore casing.

A non-curable injectable ester containing packing material for use in the repair of leaking valves contains a calcium sulfonate grease containing at least one polyalphaolefin, an ester, an anti-wear/anti-galling agent, a binding/thickening agent and a plasticizing agent.

Embodiments of the present disclosure provide for mixtures, methods for making mixtures, articles, methods for making articles, and methods of using articles.

One or more embodiments presently described are directed to lubricants and methods for making such lubricants. According to one embodiment, a lubricant suitable for use in a water-based drilling fluid may comprise one or more alkyl esters and a fatty acid blend comprising at least palmitic acid and stearic acid. The sum of the weight percent of the palmitic acid and stearic acid may be at least 50 wt. % of the fatty acid blend. The weight ratio of the one or more alkyl esters to the fatty acid blend may be from 1:1 to 3:1. The molar ratio of palmitic acid to stearic acid may be from 20:80 to 40:60.

The invention relates to lubricating greases based on alkali metal soaps and/or earth-alkali metal soaps and metal complex soaps based on (R)-10-hydroxyoctadecanoic acid and to the use thereof.
