Abstract:
This invention relates to a method (and a corresponding system) of creating a cylinder oil, the method comprising modification of at least one initial fluid (101) by determining the TBN(s) of the at least one initial fluid, determining a desired TBN of a cylinder oil (102) and adjusting the TBN(s) of the at least one initial fluid (101) accordingly by blending the at least one initial fluid (101) with suited additive(s) (103). In this way, a method (and system) for modifying initial fluid(s) to create a cylinder oil by adjusting TBN is obtained. This provides significant economical benefits since lubricants that otherwise would have to be disposed of can be re-used as a total-loss cylinder lubricant. Further cylinder oil does not have to be purchased. The oil(s) used to blend the cylinder oil is/are of more consistent quality as it is replenished contrary to the traditional practice which reduces machinery wear, etc. Thus, the replenishment of the initial fluid(s) provides enhanced and consistent performance of the initial fluids resulting in greatly reduced component wear and equipment lifecycle cost. Even further, a more environmentally friendly method/system is provided since waste, in the form of spent oil(s) that is discarded after prolonged use, is reduced as it is converted into a cylinder oil.
Abstract:
The problem is to provide a protective coating-forming waterborne composition that can form, by a simple method comprising coating and drying onto a metal surface, a coating that is uniform with little unevenness and that has an excellent galling resistance and workability that are at least as good as the corresponding properties afforded by conversion treatment methodologies. ÄSolutionÜ Waterborne composition for forming protective coatings, that characteristically contains water-soluble inorganic salt and smectite-type clay mineral. The lubrication performance of the coating can also be improved when said composition additionally contains a lubricating component.

A grease composition for constant velocity joints consists essentially of: (a) a base oil; (b) an urea thickener; (c) molybdenum disulfide; (d) a calcium salt or an overbasic calcium salt selected from the group consisting of calcium salts or overbasic calcium salts of oxidized waxes, petroleum sulfonates, alkyl aryl sulfonates, salicylate, and phenates; (e) a metal-free sulfur-phosphorus extreme pressure agent; and (f) molybdenum dithiocarbamate. The grease composition exhibits excellent wear-resistance and pitting-inhibitory effect.

PURPOSE: To provide uniform motion joint grease compositions having a high effect of reducing inductive thrust and excellent durability. CONSTITUTION: Uniform motion join grease compositions comprise (a) a base oil, (b) a diurea based thickening agent represented by the formula: R1NH-CO- NH-C6H4-p-CH2-C6H4-p-NH-CO-NHR2 (wherein R1 and R2 are each a 6C or 7C aryl group or a cyclohexyl group), (c) a dialkyl sulfide molybdenum dithiocarbamate, (d) a dialkyl sulfide molybdenum dithiophosphate, (e) molybdenum disulfide, (f) a calcium alkylaromatic sulfonate, and (g) a phosphorus-free, sulfur-based extreme-pressure additive.
Abstract:
A lubricant additive for gear oils and an improved gear oil are disclosed. The additive comprises about 0.01 to about 65 percent, by weight, of solid lubricant particles selected from the group consisting of molybdenum disulfide, graphite, cerium fluoride, zinc oxide, tungsten disulfide, mica, boron nitrate, boron nitride, borax, silver sulfate, cadmium iodide, lead iodide, barium fluoride, tin sulfide, fluorinated carbon, PTFE, intercalated graphite, zinc phosphide, zinc phosphate, and mixtures thereof; combined with about 0.1 to about 25 percent, by weight, of a stabilizing agent consisting of an ethylene-propylene copolymer; and a fluid carrier. The lubricant additive provides the gear oil with improved demulsibility, stability, and compatibility characteristics of the gear oil when contaminated with water.
Abstract:
A water-soluble metal-working composition is provided which comprises a relatively large alkoxylated amine, an alkanolamine and an acid-derived compound selected from organic acids, inorganic acids, and salts thereof.
Abstract:
Novel lubricant compositions contain at least one rare earth halide, e.g., cerium trifluoride, and at least one surfactant including a hydrophobic moiety and a hydrophilic moiety, such hydrophilic moiety comprising ethylene oxide and/or propylene oxide units and, optionally, hydrophilic functional groups, dispersed in an oily medium compatible therewith.
Abstract:
The invention provides a powder coating composition comprising of thermoplastic polymers, ceramic particles, and cermet particles for lowering the friction coefficient, and improving wear and corrosion resistance of coated surfaces in high-temperature, high-pressure, and corrosive environments. It also provides a method of coating application for improving adhesion of the coating to the substrate. The coating compositions are devoid of volatile organic solvents and can be applied on surfaces using thermal spraying, compression molding and other particle sintering approaches. A multilayer architecture consisting of an adhesive bottom layer and a non-adhesive, low friction top layer is disclosed. The coating can be used in oil and gas production and seawater injection.
