Abstract:
A lubricant additive produced by the process comprising mixing a metal halide with an organophosphate, the metal halide participating as a reactant and reacting the metal halide and the organophosphate to produce a reaction mixture comprising the lubricant additive. Also disclosed is a lubricant produced by the process comprising forming a lubricant additive by reacting metal halide and organophosphate together to form a reaction mixture, the metal halide participating as a reactant, and adding at least a portion of the reaction mixture to a lubricant base.
Abstract:
The present invention provide a two-component anti-seizure agent for hot metal working process comprising the first aqueous solution and the second aqueous solution, wherein the first aqueous solution contains 10~30 mass % of sodium silicate equivalent to anhydride to 100 mass % of total mass of the first aqueous solution, and the second aqueous solution contains at least one kind Selected from a group consisting of: an organic acid and water-soluble amine salts thereof, an inorganic acid and water-soluble amine salts thereof, a water-soluble amine, a water-soluble alcohol, and a water-soluble metal chloride. When the two-component anti-seizure agent is applied onto disk-roll type guide shoes, it can be provided and maintained on the circumferential surface of the disk-roll type guide shoes without washed away by rolls' cooling water. Thereby, the anti-seizure agent does not adhere to rolls and the rolls and a pipe material do not cause slippage each other. Thus, it is capable to carry out piercing-rolling of the pipe material.
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:
Lubricating oils exhibiting anti rust properties are obtained by adding to the lubricating oil an acidic anti rust additive and an acid scavenger such as carbodiimide, in a specific sequence.
Abstract:
A stainless steel wire is plated with nickel (Ni) to a thickness of from not less than 1 mu m to not more than 5 mu m. An inorganic salt coat film mainly composed of at least one of potassium sulfate and borax (borate) and free from fluorine (F) or chlorine (Cl) is then deposited on the nickel (Ni) plate 2 as the substrate. The steel wire is then drawn to a reduction of area of not less than 60% to adjust the surface roughness thereof to a range of from 0.80 to 12.5 mu mRz, preferably from 1.0 to 10.0 mu mRz.
Abstract:
Dry film lubricant coatings are provided by using a silicone resin binder, either as an aqueous emulsion or in a solvent-based system, to fix an alkaline earth metal fluoride to a substrate. The compositions used to apply the coatings may also include relatively minor amounts of xylene, ammonium benzoate, a wetting agent, and/or a porosity-inducing agent-although none of those additives remains in the cured coating. Multi-layer dry film lubricant coatings are also disclosed, with the multi-layer coating having a basecoat layer as described above, and a topcoat layer made of a layer-lattice solid such as graphite or molybdenum disulfide, and a silicone resin, aluminum phosphate or an alkali metal silicate binder.
