A corrosion-resistant dry film lubricant composition includes a lubricating pigment, a binder, and a solvent. The lubricating pigment comprises graphene platelets and is dispersed in the binder, and the solvent solubilizes the lubricant pigment and the binder. The graphene platelets are oxidized and functionalized with a silane. A method of producing a corrosion-resistant lubricant includes oxidizing exfoliated graphene to produce oxidized graphene platelets, functionalizing the oxidized graphene platelets with a silane to produce functionalized graphene platelets, and dispersing the functionalized graphene platelets in a lubricant composition, wherein the lubricant composition comprises a binder and a solvent.

A corrosion-resistant wet film lubricant composition includes a lubricating pigment, an oil, and a thickener. The lubricating pigment comprises graphene platelets and is dispersed in the oil, and the thickener thickens the wet film lubricant. The graphene platelets are oxidized and functionalized with a silane. In another example, a method of producing a corrosion-resistant lubricant includes oxidizing exfoliated graphene to produce oxidized graphene platelets, functionalizing the oxidized graphene platelets with a silane to produce functionalized graphene platelets, and dispersing the functionalized graphene platelets in a lubricant composition, wherein the lubricant composition comprises an oil and a thickener.

A method is provided that forms a solid film on a bearing component of a rolling bearing. A solution containing a fluorine compound and a lubricant having no functional group is allowed to adhere to the bearing component as a first liquid film (adhesion step). The adhering first liquid film is hardened to form the solid film on the bearing component. The rolling bearing including the bearing component with the solid film formed thereon is rotated. The rolling bearing is washed in a washer fluid containing the same lubricant as that used in the adhesion step, and the washer fluid is allowed to adhere to the bearing component as a second liquid film. Then, the adhering second liquid film is dried.

This disclosure provides low viscosity, low volatility alkylated siloxane compounds and alkylated alkoxy silane compounds. This disclosure also provides processes for producing the alkylated siloxane compounds and alkylated alkoxy silane compounds, and lubricating oil basestocks and lubricating oils containing one or more of the alkylated siloxane compounds or one or more of the alkylated alkoxy silane compounds. This disclosure further provides a method for improving one or more of solubility and dispersancy of polar additives and/or sludge in a lubricating oil by using as the lubricating oil a formulated oil containing one or more of the alkylated siloxane compounds or one or more of the alkylated alkoxy silane compounds.

Provided is a one-pack type ultraviolet-thickable thermally conductive silicone grease composition which, at the initial stage, has a low viscosity (is easy to apply) but has high shape retentivity and which, after curing, is pliable (has low hardness). The ultraviolet-thickable thermally conductive silicone grease composition comprises, as essential components, (A) an organopolysiloxane having a viscosity at 25° C. of 50-100,000 mPa.Math.s and containing at least one alkenyl group in the molecule, (B) a liquid organohydrogenpolysiloxane which has a viscosity at 25° C. of 100 mPa.Math.s or less, contains 2-10 silicon-atom-bonded hydrogen atoms in the molecule and contains at least one alkoxy and/or epoxy group bonded to a silicon atom through an alkylene group and in which the polysiloxane has a degree of polymerization of 15 or less and the skeleton of the polysiloxane includes a cyclic structure, (C) a photoactivable platinum complex curing catalyst, and (D) a thermally conductive filler having a thermal conductivity of 10 W/m.Math.° C. or greater.

A lubricant composition includes a base lubricant and a plurality of lubricant additive molecules. Each lubricant additive molecule includes a surface active group attractable to a target surface, and a carbon containing component connected to the surface active group, for providing a carbon source to form a carbon film on the target surface. A method for in situ forming of a carbon film using the lubricant composition, includes adding the lubricant composition into a target machine such that the lubricant composition is in contact with a target surface of the target machine, and operating the target machine to cause a temperature and a pressure at the target surface so that the carbon containing component is unraveled thereon to form a carbon film on the target surface during the operation.
