A pre-lubricated stock sheet and a method and system for making the same are described. The pre-lubricated stock is generally in a coil wound form. The stock sheet can have opposing first and second sheet surfaces joined together by opposing side edges and opposing ends. Typically, the first and second sheet surfaces are substantially smooth and planar, wherein the sheet has 3 mg/foot.sup.2/side to about 200 mg/foot.sup.2/side of a solid lubricant having a melting temperature from about 80 to 212 degrees Fahrenheit. Moreover, the opposing side edges usually are substantially free of the solid lubricant. In some configurations, the stock sheet is an aluminum stock sheet, more particularly an aluminum can stock sheet. Furthermore, the lubricant can be in some configurations a food grade lubricant, that is qualifies a low volatile organic compound under one or more of municipal, state and federal governing authorities.

Specifically, the metal shaping composition discussed herein are environmentally-friendly, water-containing composition which provide excellent lubricity under metal shaping process conditions while also providing excellent rust protection. The metal shaping compositions discussed herein contain (i) a film-forming lubricant capable of being solubilized into water in dispersible or emulsifiable form and which softens at a temperature of about 80 to about 200 C.; (ii) a film forming polymeric binder capable of being solubilized into water in dispersible or emulsifiable form; (iii) a solid lubricant capable of being solubilized into water in dispersible or emulsifiable form; and (iv) a corrosion inhibitor.

A lubricating oil for press working contains a base oil and a fat or oil-containing additive and a calcium-containing additive added to the base oil. The proportion of the fat or oil-containing additive with respect to the whole volume of the lubricating oil for press working is 10 to 30%. The proportion of the calcium-containing additive with respect to the whole volume of the lubricating oil for press working is 5 to 15%.

A water-soluble quenching fluid composition prepared by blending: water, at least one kind selected from a polyoxyalkylene glycol and a derivative thereof (A), and at least one kind selected from an alkylene glycol ether (B) and a monocarboxylic acid (C), the polyoxyalkylene glycol or a derivative thereof (A) having a mass average molecular weight of 10,000 or more and 100,000 or less, the alkylene glycol ether (B) having a boiling point of 200 C. or more and a molecular weight per 1 mol of 1,000 g/mol or less.

Forge lubrication processes are disclosed. A solid lubricant sheet is placed between a workpiece and a die in a forging apparatus. Force is applied to the workpiece with the die to plastically deform the workpiece. The solid lubricant sheet decreases the shear factor for the forging system and reduces the incidence of die-locking.

Provided are microalgal compositions and methods for their use. The microalgal compositions include lubricants that find use in industrial and other applications.

A process for surface treatment of metal substrates, including the steps of: providing a metal substrate including hydroxyl groups at its surface; bringing the metal substrate into contact with a solution of at least one organophosphorus compound to enable the reaction of the hydroxyl groups at the surface of the metal substrate with the organophosphorus compound to form a monomolecular layer over the surface and a second layer of physisorbed organophosphorus molecules at least preponderantly crystallized, the obtained treated substrate being coated with the organophosphorus compound in the form of a first monomolecular layer coating at least 15% of the surface of the substrate and in the form of a physisorbed second layer at least preponderantly crystallized. A treated metal substrate which may be obtained by the process thereof, corresponding solution and its use for treating metallic substrates to improve their tribological properties during their shaping, in particular their stamping.

The present invention relates to a method for reconditioning bearing lubricants that can be used in equipment for metal working, in which cooling lubricant that can be used in equipment for metal working is separated from the bearing lubricant. In addition the invention relates to a bearing lubricant for use in the method according to the invention.

The present disclosure is directed to an aqueous lubricating composition comprising, based on the weight of the composition: from 1 to 20 wt. % of a) at least one water-soluble inorganic salt, said inorganic salt or salts being in a dissolved state; b) at least one particulate solid lubricant; from 0.1 to 5 wt. % of c) at least one rheological control agent; from 0.1 to 5 wt. % of d) at least one base; and, from 0.1 to 5 wt. % of e) at least one surfactant selected from the group consisting of anionic surfactants, nonionic surfactants, cationic surfactants, amphoteric surfactants and zwitterionic surfactants, wherein said composition is free from boron and boron compounds and is further characterized in that the ratio by weight of b) said at least one solid lubricant to a) said at least one water-soluble inorganic salt [(b):(a)] is from 0.1:1 to 1:1.

Provided is a solid lubricant that is non-black in color and capable of reducing industrial waste (environmental conservation), and further capable of achieving a balance among excellent lubricity, moisture absorption resistance, and corrosion resistance in a heavy working region, and a lubricating coating agent including the solid lubricant.

A solid lubricant including carrier particles including a lipophilic lubricating component that is at least one of an oil, an extreme-pressure agent, a soap, and a wax between particles of and/or between layers of at least one layered clay mineral selected from the group consisting of natural products and synthetic products of a smectite group, a vermiculite group, a mica group, a brittle mica group, a pyrophyllite group, and a kaolinite group.
