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:
Lubricant oil and grease composition containing an additive package comprising wear-resistant additives in the form of nanoparticles, wherein the additives are a carbonate selected from the group consisting of a carbonate of a Group 1a alkali metal and a carbonate of a Group 2a alkaline earth metal, a sulfate of a Group 1a alkali metal or a Group 2a alkaline earth metal, a phosphate of a Group 1a alkali metal or Group 2a alkaline earth metal, a carboxylate of a Group 1a alkali metal and a carbonate of a Group 2a alkaline earth metal, or a combination thereof.
Abstract:
A composition for treating the surface of a ferrous metal. The composition comprises aluminum sulfate, boric acid or a boric acid precursor, and polycarboxylic acid or salt thereof. Treatment of the ferrous metal with an aqueous solution of the composition at elevated temperature and low pH provides a coating that imparts lubricity to the metal, thereby facilitating metal working processes such as drawing for wire production.

Abstract:
According to the invention there is provided a method of reducing wear of one or both of two steel elements having surfaces in sliding or sliding-rolling contact. The method involves applying an HPF friction control composition to one, or more than one contacting surface of one or both of the two steel elements. In a particular example, the HPF friction control composition comprises a rheological control agent, a lubricant, a friction modifier, and one, or more than one of a retentivity agent, an antioxidant, a consistency modifier, and a freezing point depressant.
Abstract:

Abstract:
An aqueous one step type lubricating agent for efficient cold forging, characterized in that it comprises (A) a water-soluble inorganic salt, (B) a wax and (C) a metal salt of a fatty acid in a form dissolved or dispersed in water, wherein weight ratios of solid contents are 0.60 to 0.70 for (B)/(A) and 0.1 to 0.3 for (C)/(A). The water-soluble inorganic salt can be selected from among a sulfate, a silicate, a borate, a molybdate and a tungstate. As the wax, use can be made of a synthetic wax being dispersible in water and having a melting point of 70 to 150 DEG C. As the metal salt of a fatty acid, use can be made of a reaction product of a saturated fatty acid having 12 to 26 carbon atoms with at least one metal selected among zinc, calcium, barium, aluminum and magnesium.
Abstract:
A water-based composition for protective film formation, characterized by containing a water-compatible inorganic salt and a smectite clay mineral. By merely applying the composition to a surface of a metallic material and drying it, a coating film can be formed which is less apt to have spots and is even, and is equal or superior in processability and seizing resistance to coating films formed by a chemical treatment. In the case where the composition further contains a lubricating ingredient, the coating film can further have improved lubricity.
