The viscosity of the composition is about 50 to 700 cps.
Abstract:
A new organic lubricant for lubricating and cooling tools. The inventive composition is prepared by soaking an amount of okra in a volume of water for a length of time and then straining said okra from the mixture of water and okra so that the remaining mixture forms the organic lubricant. Optionally, the remaining mixture may further evaporated to form a concentrated version of the organic lubricant. Also optionally, preservatives may be added to the organic lubricant to delay the fermentation or decomposition of the organic lubricant.

An article having a multiphase composite lubricant coating of a hard refractory matrix phase of titanium nitride dispersed with particles of a solid lubricating phase of molybdenum disulfide is prepared by heating the article to temperatures between 350.degree. and 850.degree. C. in a reaction vessel at a reduced pressure and passing a gaseous mixture of Ti((CH.sub.3).sub.2 N).sub.4, MoF.sub.6, H.sub.2 S and NH.sub.3 over the heated article forming a multiphase composite lubricant coating on the article.
Abstract:
The invention provides composites of organic polymeric compositions including a matrix of an organic polymer and a filler distributed throughout the matrix, the flier being present in the matrix substantially as separate particles, each about the fundamental particle size of the filler. The fillers are unique mixed metal hydroxide compositions that are obtainable in sub-micron size particles. These particles are layered and have a BET specific surface area in excess of about 100 m.sup.2 /g. An anion of the particulates is selected to be compatible with the organic polymer thereby providing ease of dispersion of the filler particles throughout the polymer matrix.
Abstract:
A composition of matter for depositing a thin anti-friction film that has a coefficient of friction of 0.06 or less. The composition comprises (a) a mixture of solid lubricant particles, a thermoset resin, and a catalyst for setting the resin, and (b) an evaporative medium for carrying the mixture during deposition. A solid film lubricant system for protecting metal wear interfaces subject to high temperatures and wet lubrications, comprising an oil-attracting solid lubricant mixture with at least two elements selected from the group of graphite, MoS.sub.2 and BN; a support for the mixture to loads of at least 10 psi at temperatures of 600.degree.-800.degree. F. while being thermally stable; a thermally stable thermoset polymer matrix, the polymer having inherent hydrocarbon chemical attraction to form a tenacious oil film of the lubricating oil on the wearing surface. A method of making anti-friction coated surfaces comprising providing a light metal based cylinder surface; exposing nonoxidized metal of the surface; applying a high elastic modulus load-supporting metal layer onto at least portions of the light metal cylinder surface; and simultaneously distributing a solvent-based solid film lubricant mixture and thermoset polymer onto at least portions of the layer at about room temperature to form a coating of desired thickness.
Abstract:
A lubricant for the topical application to objects that will contact various forms of water, e.g., liquid, snow, ice, or mixtures thereof, to reduce friction and thereby increase speed, glide and maneuverability. The lubricant consists essentially of hexagonal boron nitride and a binder of single or mixed oxides or organics, the boron nitride content (after drying) being from about 36 wt. % to about 99 wt. %. Binders of particular interest are water-based colloidal aluminum oxide and colloidal silicon dioxide. This lubricant is suitable for topical applications in a thin layer to various sports objects, such as skis, snowboards, ice skates, snowmobiles, toboggans, sleds, boats, etc., where reduced friction, and thus higher speed, glide and maneuverability is desired. Although a solid stick form (by drying or pressure-less sintering) is preferred, the lubricant can be in the form of a paste or a powder. Further, this lubricant can be incorporated into waxes of the type previously used for friction reduction to obtain the benefit of both.
Abstract:
A lubricating composition for use in hot rolling comprises from about 20% to about 70% by weight, based on the total weight of the composition, of an overbased metal sulfonate, e.g., overbased calcium sulfonate, having a base number of at least about 40 mg-KOH/g and preferably at least 200 mg-KOH/g. The lubricating composition can be applied to at least one pair of work rolls in a rolling mill during hot rolling of a steel. It may also be applied to the steel itself immediately before hot rolling. The lubricating composition is effective for preventing galling and reducing roll wear without causing slippage of the steel and it is particularly suitable for use in hot rolling of carbon steel under severe conditions or of stainless steel including high-Cr stainless steel.
Abstract:
A noble metal and solid-phase lubricant composition and an an electrically conductive interconductor including the electrically conductive composition are disclosed. The electrically conductive composition includes a noble metal component and a solid-phase lubricant component. The solid-phase lubricant component is present in an amount sufficient to cause the electrically conductive composition to have a coefficient of friction which is significantly lower than the coefficient of friction of the noble metal component without causing the electrically conductive composition to be significantly less malleable than the noble metal component, nor to be significantly less corrosion resistant than the noble metal component. The electrically conductive composition can form a contact layer of the electrically conductive interconnector. The contact layer is bonded to a diffusion barrier which, in turn, is bonded to a bulk electrical conductor of the electrically conductive interconnector.
Abstract:
In the cold drawing of steel tubing, an excellent lubrication which permits drawing the tubing while retaining its original metallic luster can be achieved by first contacting the surfaces of the tubing, both exterior and interior, with a colloidal titanium containing aqueous composition, drying the tubing, and then applying to the surface of the tubing a liquid lubricating composition comprising (i) from 40 to 95% of a first component selected from the group consisting of olefin/oil or olefin/fat compounds which contain from 23 to 30% of sulfur and olefin/higher ester compounds which contain from 23 to 30% sulfur, including mixtures of two or more chemical species meeting this description; and (ii) from 5 to 50% of a second component selected from the group consisting of oil soluble polymer compounds, fats and oils, synthetic oils, mineral oils, higher fatty acids, and the amine salts of higher fatty acids.
