Abstract:
A composition and method for providing a wear-resistant and fuel-saving coating on metals, particularly metal surfaces within internal combustion engines. A source of ammonium ions, an alkali metal in an aqueous medium, and the coating metal to be applied to the surface are combined to produce an electrolyte solution comprising a complex ion mixture. The electrolyte solution can be used to deposit the coating metal on conductive substrates. The coating metal may comprise phosphorus, sulfur, carbon, bismuth, boron, silicon, and combinations thereof. The electrolyte solution can be dehydrated in a hydrocarbon medium, thus providing novel materials for use as lubricating oil additives and as fuel additives. These new surfaces may significantly reduce coefficient of friction, smooth the flame front, reduce corrosion, enhance fuel economy, and reduce hydrocarbon emissions when used in internal combustion engines.

Lubricating compositions including crystalline boric acid and a base lubricant selected from oils, greases and the like. The lubricity of conventional oils and greases can also be improved by adding concentrates of boric acid.
Abstract:
A lubricant composition for the plastic working of metals that does not require a phosphate undercoating, is waterborne, requires only a simple application process of immersion or spraying followed by drying, and provides an excellent lubricating performance comprises synthetic resin, water-soluble inorganic salt, and water. The weight ratio of the content of salt to that of synthetic resin is from 0.25:1 to 9:1. This composition can also contain liquid and/or solid lubricating agent(s) and extreme pressure additive.

PCT No. PCT/CA97/00658 Sec. 371 Date Jun. 22, 1999 Sec. 102(e) Date Jun. 22, 1999 PCT Filed Sep. 11, 1997 PCT Pub. No. WO98/13445 PCT Pub. Date Apr. 2, 1998The present invention relates to novel lubricant compositions comprising a solid lubricant and a binding agent in water medium suitable for lubricating steel-steel interfaces such as tractor-trailer couplings, rail-wheel systems and other heavy duty applications. The invention also relates to compositions described above which include friction modifiers with high or very high and positive coefficients of friction such that the coefficient of friction is considerably higher than the solid lubricant. The invention further relates to compositions comprising a binding agent and a friction modifier with a very high and positive coefficient of friction in a water medium.
Abstract:
A silicon elastomer compatible constant velocity joint grease comprises a urea grease composed of a lubricating oil and a urea thickener and an effective amount of a friction reducing additive package comprising vermiculite, molybdenum oxysulfide dithiocarbamate, polyphenylene sulfide and potassium triborate. The additive package solids have particle sizes below about 40 microns.
Abstract:
A lubricant and surface conditioner for formed metal surfaces, particularly beverage containers, reduces the coefficient of static friction of said metal surfaces and enables drying said metal surfaces at a lower temperature. An aqueous composition for forming the conditioner by contact with metal surfaces includes a water-soluble organic material selected from a phosphate ester, alcohol, fatty acid including mono-, di-, tri-, and polyacids; fatty acid derivatives such as salts, hydroxy acids, amides, esters, ethers and derivatives thereof; and mixtures thereof and at least one of the elements selected from zirconium, titanium, cerium, aluminum, iron, tin, vanadium, tantalum, niobium, molybdenum, tungsten, and hafnium in metallic or ionic form. In order to avoid formation of sludge in the aqueous lubricant and surface conditioner forming composition, the composition should contain as little as possible of materials containing phenanthrene rings, such as conventional surfactants made by ethoxylating rosin. In order to assure the minimization of such surfactants in the aqueous lubricant and surface conditioner forming composition, surfactants containing phenanthrene rings should also be avoided or minimized in earlier cleaning stages.
Abstract:
Contact of acid or alkaline cleaned aluminum surfaces, particularly cans, with a water based composition containing a combination of (i) alkoxylated phosphate esters, (ii) ions of aluminum, zirconium, iron, tin, and/or cerium, (iii) a metal etching component, and (iv) a combination of alkoxylated alcohol and alkoxylated alkyl phenol emulsifiers, gives the surface after drying lowered surface friction without loss of high quality printability and lacquer adhesion and removes any brown spotting on the cans that may have developed during the cleaning or post-cleaning rinses. The cans after treatment are substantially free from any water breaks when rinsed with water. The foaming resistance and storage stability of the water based composition as described above, and of other similar surface friction reducing treatments for aluminum containers, may be advantageously increased by adding a biocidal agent, preferably hydrogen peroxide, and a combination of liquid paraffin, solid wax, and a high molecular weight fatty acid derivative(s) as antifoam agent.
Abstract:
A graphite-free lubricating oil which comprises a base oil having dispersed therein 10 to 40% by weight of a carbohydrate and/or a derivative thereof whose particle size ranges from 10 to 150 µm, 2 to 20% by weight of a film-boosting agent and 0.1 to 20% by weight of a dispersant. Moreover, the lubricating oil is free of black-colored substances such as graphite. Therefore, the oil permits the improvement of working surroundings and exhibits excellent properties such as formability through forging almost comparable to or even greater than that of the commercially available graphite-in-oil type lubricating oils. The lubricating oil can be used instead of the graphite-containing lubricating oils for warm forging, hot forging, rolling, tube-manufacturing, drawing and extrusion in place of the graphite-containing lubricating oils and ensures the improvement in the working surroundings and excellent lubricity.
Abstract:
A rheologically controlled glass lubricant for hot metal working comprises a glass powder, a binder, a rheological agent, and a weetting and viscosity modifier. These materials may be dispersed in a carrier. The lubricant is made by mixing the constituent elements, milling the mixture, and stabilizing the milled mixture. The lubricant can be used in a forging operation by coating a metal part with the lubricant, heating the coated part, placing the coated heated part in a forge, and rapidly applying sufficient pressure to deform the coated metal part into a desired shape.
