The present invention provides a contact member that strikes a balance between low electrical resistance and sliding durability. A contact member of the invention has a metal base and a coating disposed on at least part of the metal base. The coating contains fluorinated oil having a polar group, and metal particles surface-treated with a fluorine-based compound having a polar group.

The present invention provides a contact member that strikes a balance between low electrical resistance and sliding durability under the condition of load as low as about 0.1 N. A contact member of the invention has a metal base and a coating disposed on at least part of the metal base. The coating contains fluorinated oil having a polar group, and metal particles surface-treated with a fluorine-based compound having a polar group.

Disclosed are liquid coolants for electric systems and methods of making the same. An example liquid coolant for electric systems may comprise: a base oil, wherein the base oil is a major component of the liquid coolant; and a dissolved gas in an amount sufficient to have a measurable effect on fluid viscosity of the liquid coolant; wherein the liquid coolant has a kinematic viscosity at 100° C. of about 7 cSt or less.

A dielectric nanolubricant composition is provided. The dielectric nanolubricant composition includes a nano-engineered lubricant additive dispersed in a base. The nano-engineered lubricant additive may include a plurality of solid lubricant nanostructures having an open-ended architecture and an organic, inorganic, and/or polymeric medium intercalated in the nanostructures and/or encapsulate nanostructures. The base may include a grease or oil such as silicone grease or oil, lithium complex grease, lithium grease, calcium sulfonate grease, silica thickened perfluoropolyether (PFPE) grease or PFPE oil, for example. This dielectric nanolubricant composition provides better corrosion and water resistance, high dielectric strength, longer material life, more inert chemistries, better surface protection and asperity penetration, no curing, no staining, and environmentally friendly, compared to current products in the market.

A self-lubricating composite material is disclosed. The self-lubricating composite material can include discontinuous polymer fiber segments dispersed within a woven matrix of semi-continuous thermoplastic fiber. The woven matrix can be embedded within a thermosetting resin. Also disclosed are methods of manufacturing the self-lubricating composite material.

A sliding member has a sliding surface sliding under a wet condition in which a lubricant oil exists. The sliding surface is coated with a laminate film comprising an upper layer and a lower layer. The lower layer comprises hydrogen-free amorphous carbon (hydrogen-free DLC) and carbon particles dispersed on or in the hydrogen-free DLC. The hydrogen-free DLC has a hydrogen content of 5 atom % or less when the lower layer as a whole is 100 atom %. The upper layer comprises boron-containing amorphous carbon (B-DLC) and has protrusions on a surface side of the upper layer along the carbon particles of the lower layer. The B-DLC has a boron content of 1-40 atom % when the upper layer as a whole is 100 atom %. The protrusions have a particle diameter of 0.5-5 m and exist with a density of 20 protrusions/100 m.sup.2 or more.
