Abstract:
Provided is an innovative belt-shaped lubricating material for dry wiredrawing which not only can be used under severe wiredrawing processing conditions such as those of high temperature/high pressure/high speed as well as conventional powdered or granular lubricants for dry wiredrawing but also can cope with diameter reduction to a wide range of wire diameters ranging from a small diameter to a large diameter and a wide range of linear speeds ranging from a low speed to a high speed, has excellent functionalities such as lubricity, followability, spreadability, adhesiveness, heat resistance, processability, workability, safety, durability and productivity irrespective of a processed shape, is effective in improving work environments and is friendly to the global environment.The belt-shaped lubricating material for dry wiredrawing includes a film containing 10 to 90% by weight of a metal salt of a saturated fatty acid and 10 to 90% by weight of a thermoplastic resin.
Abstract:
A manufacturing method for providing a low-friction surface comprises providing (210) of a mechanical element. A tool is mechanically rubbed (212) against a surface of the mechanical element. A process liquid is provided (214) to a contact area between the mechanical element and the tool. The process liquid comprises a first element that is a refractory metal and a second element that is a chalcogen. The first and second elements are provided in a liquid substance. The mechanical rubbing is performed with a contact pressure that is between 1% and 100% of an ultimate strength of the mechanical element. The mechanical rubbing thereby causes a combined burnishing of the surface of the mechanical element and a deposition of a tribofilm on the surface of the mechanical element. The tribofilm comprises the first element and the second element.
Abstract:
A process for the in-situ formation of a lubricating phase comprising sulphur and tin in a friction material, wherein reaction of a sulphur source with a tin source in said friction material results in the formation of said lubricating phase, and wherein said reaction is initiated or effected by heat resulting, in use, from the generation of friction, wherein said sulphur source is selected from one or both of sulphur and/or a metal sulphide selected from one or more of iron, copper, zinc, titanium and bismuth, and wherein said tin source is selected from one or more of tin, a tin-containing compound and/or a tin-containing alloy.
Abstract:
Certain preferred embodiments of the present invention relate to compositions for the production of sintered molded parts, components/parts produced therefrom, and methods for preparing such compositions. In accordance with certain embodiments, compositions for production of sintered molded parts comprise a metal-based, a ceramic-based, and/or a polymer-based powder, and a compaction aid, having 25 to 60 weight percent of a polyglycol, based on the total weight of the compaction aid, and 40 to 75 weight percent of a montan wax, based on the total weight of the compaction aid. The compaction aid may be present in an amount from about 0.1 to 5 weight percent, preferably 0.5 to 1.5 weight percent, based on the total weight of the composition. The composition may also include a lubricant such as, for example, MoS2, WS2, BN, MnS, and/or carbon.
Abstract:
A lubricant suitable for use in an industrial forming process, especially cold pilgering, comprises a polyglycol as base fluid, a water-soluble inorganic filler and an organic filler.
Abstract:
A method for treating the phosphate sludge waste from phosphate conversion baths used in the metal forming and metal working industry is described whereby the phosphate sludge is completely converted into a lubricant additive which can be used in lubricant formulations for the metal forming and metal working industry as well as general purpose lubricants. By operation of this process, waste treatment and waste disposal problems associated with the phosphate sludge are essentially eliminated. Various dry-soap lubricant formulations, warm forming lubricant formulations, non-reactive lubricant formulations, and metal precoat formulations containing the recovered or recycled phosphate sludge additive are described. The lime normally contained in many of these lubricant formulations can be significantly reduced or essentially eliminated by using the recovered phosphate sludge additive of this invention, thereby resulting in improved lubricant formulations. The recovered phosphate sludge is especially useful as an Extreme Pressure Additive.
Abstract:
A process for producing a mixture of sulfides of alkaline earth metal salts of an alkylhydroxybenzoic acid and an alkylphenol comprising the steps of: reacting a mixture of a phenol, a dihydric alcohol and an alkaline earth metal oxide and/or hydroxide (hereinafter referred to as an alkaline earth metal reagent) in an amount of no more than 0.99 gram equivalents per gram equivalent of said phenol; distilling off water and the dihydric alcohol until the amount of the dihydric alcohol becomes no more than 0.6 moles per mole of the alkaline earth metal reagent; reacting the resulting distillation residue with carbon dioxide; and reacting the resulting product with elemental sulfur in an amount of 0.1-4.0 moles per mole of the alkaline earth metal reagent.
Abstract:
A lubricating oil additive is prepared by reacting a triglyceride with a basic nitrogen compound to form a reaction product, reacting said reaction product with an acidic molybdenum compound to form an intermediate reaction product, and reacting said intermediate reaction product with a sulfur compound to produce a lubricating oil additive.
