A wear and/or friction reducing additive for a lubricating fluid in which the additive is a combination of a moderately hydrophilic single-phase compound and an anti-wear and/or anti-friction aqueous salt solution. The aqueous salt solution produces a coating on boundary layer surfaces. The lubricating fluid can be an emulsion-free hydrophobic oil, hydraulic fluid, antifreeze, or water. Preferably, the moderately hydrophilic single-phase compound is sulfonated castor oil and the aqueous salt solution additionally contains boric acid and zinc oxide. The emulsions produced by the aqueous salt solutions, the moderately hydrophilic single-phase compounds, or the combination thereof provide targeted boundary layer organizers that significantly enhance the anti-wear and/or anti-friction properties of the base lubricant by decreasing wear and/or friction of sliding and/or rolling surfaces at boundary layers.

Novel materials as additives for advanced lubrication

Номер: US20130079262A1
Автор: Ali Erdemir, Kuldeep MISTRY, Michael M. Thackeray, Vilas G. Pol
Принадлежит: UChicago Argonne LLC

This invention relates to carbon-based materials as anti-friction and anti-wear additives for advanced lubrication purposes. The materials have various shapes, sizes, and structures and are synthesized by autogenic reactions under extreme conditions of high temperature and pressure. The lubricant compositions comprise carbon-based particles suspended in a liquid hydrocarbon carrier. Optionally, the compositions further comprise a surfactant (e.g., to aid in dispersion of the carbon particles). Specifically, the novel lubricants have the ability to significantly lower friction and wear, which translates into improved fuel economies and longer durability of mechanical devices and engines.

A method and chemical composition and material structure for improving fretting wear in substrates, particularly carbon-carbon composite (CCC). The invention relates to trilayer coatings, comprising a base of hard ZrO 2 , a middle layer of Al 2 O 3 , and atop layer of lubricious ZnO. The coatings of the present invention exhibit conformality and pore-filling down to approximately 100 microns into a carbon-carbon composite to which they are applied. The methods for preparing the coatings include a chemical vapor infiltration route, such as an atomic layer deposition (ALD) process, to uniformly and conformally coat the porous and open structure of CCC with a solid lubricant trilayer of ZnO/Al 2 O 3 /ZrO 2 that results in significant improvement (65%) in fretting wear.

The pipe end correction method for correcting an inner diameter of pipe end of a seamless pipe made of a high Cr stainless steel containing 8 to 35 mass % Cr, and 0.1 to 10 mass % Ni includes a pipe end correction step following hot tube-making and heat treatment, that forces a plug into the inside of pipe end portion for inner diameter correction so as to expand the pipe end portion while oxide scale, which is generated during tube-making or heat treatment, remains accumulated on an inner surface of the pipe end portion. A lubricant film forming step, prior to the pipe end correction step, applies lubricant at least either on the inner surface of the pipe end portion of the seamless pipe or on a surface of the plug. Seizure flaws can be prevented on the inner surface of the pipe end portion of the high Cr stainless steel.

A solid-state lubricant composition is disclosed. The solid-lubricant contains graphene, an oxide of a metal, and one or more polymeric binders. A method of making a solid-state lubricant coating on various substrates is disclosed. The method includes the steps of making a homogeneous slurry comprising powder of an oxide of a metal, graphene, and a polymeric binder with organic volatile solvent; coating a substrate with the homogeneous slurry with desired thicknesses; and drying the slurry on the substrate naturally or applying additional heat, resulting in a solid lubricant coating on the substrate. Substrates with coated solid composite lubricant show wear reduction and lower coefficient of friction compared with uncoated substrates.

A composition for an aqueous tacky lubricant, specifically targeted towards increasing lubricant retention to the moving components of chainsaws. More specifically, the composition includes a novel additive composition for environmentally-neutral lubricants. The ideal function of the composition would be to increase the adhesive qualities of an aqueous lubricant without compromising the coolant and lubricant roles of such a substance. To accomplish this, the composition includes an additive compound, that is made of a linear anionic polyamide and a cationic surfactant. The reaction between the linear anionic polyamide and the cationic surfactant creates a viscoelastic tackifier that helps the lubricant to cling to a moving chain thus preventing the lubricant from flinging off the chain when in motion. In other words, the additive compound is a tackifier agent, presented as novel both as an independent composition and in addition to extant lubricants. 1. A composition for a water-soluble lubricant with increased adhesive quality , comprising:a quantity of an anionic linear polyamide;a quantity of a cationic surfactant;a quantity of a water-soluble lubricant;the quantity of the anionic linear polyamide and the quantity of the cationic surfactant, being homogeneously mixed into a lubricant additive;the quantity of the water-soluble lubricant and the lubricant additive being homogeneously mixed into an aqueous tacky lubricant.2.

GER fluids are improved by the addition of a polar molecule additive. By addition of a polar molecule additive, yield stresses under electric field are improved by over 50% while the current density is reduced to less than a quarter of the original GER. The reversible response time still remains the same, and the sedimentation stability is greatly enhanced. The zero field viscosity of the modified GER fluid remains the same as that of the original GER fluid without the additive. The improved GER characteristics improve general functionality as an electrical-mechanical interface, attendant with applications to car clutches, fluid brakes, and vehicle shock absorbers.
