Abstract:
Bei einem Kolben (1) für einen Verbrennungsmotor, mit Gleitlagerflächen (5) aufweisenden Nabenbohrungen (3) zur Aufnahme eines Kolbenbolzens, soll ein Festfressen und Verschleissen von Kolbenbolzen und Nabenbohrungen hochwirksam und kostengünstig dadurch vermieden werden, indem mittels Rotationszerstäubung eine selbstschmierende Beschichtung (6) aus einem thermisch ausgehärteten Harz mit darin eingelagerten Festschmierstoffpartikeln mindestens in einem Teilbereich (Tb) direkt auf die Gleitlagerflächen aufgebracht wird.
Abstract:
A process for producing a metal wire rod for plastic working, characterized in that it comprises the steps of cleaning the surface of a wire rod of a metal such as steel, stainless steel or aluminum for 20 seconds or less, by the use of at least one cleaning method selected from the group consisting of shot blasting, sand blasting, bending, anodic pickling and cathodic pickling, contacting the resulting wire rod, for 5 seconds or less, with an aqueous treatment liquid for forming a lubricating coating film comprising at least one inorganic salt selected from the group consisting of a phosphate, a sulfate, a borate, a silicate, a molybdate and a tungstate, and at least one lubricating agent selected from the group consisting of a metal soap, a wax, polytetrafluoroethylene, molyblenum disulfide and a graphite, and drying the rod immediately after the cleaning, and the steps are carried out continuously in an in−line system, to form a lubricating coating film on the surface of the wire rod in an amount of 0.5 to 20 g/m 2 . The process allows the production of a metal material for plastic working having excellent lubricating characteristics in a short time.

Abstract:
A lubricating agent which comprises a phosphate salt (A) containing at least one divalent or trivalent metal selected from the group consisting of Zn, Fe, Mn, Ni, Co, Ca, Mg and Al, a dispersant (B), and at least one lubricant (C) selected from the group consisting of a wax and a metal salt of a fatty acid. The lubricating agent is an aqueous agent and can be used for forming a lubricating coating film suitable for a plastic working, such as forging, wire drawing or pipe drawing, of a metal material such as steel, stainless steel, titanium or aluminum, without a chemical treatment of the metal material.
Abstract:

The solid lubricant having from about twenty-five percent to about seventy percent by volume of a polymeric carrier, about five to seventy-five percent by volume of organic and inorganic extreme pressure additives, about zero to twenty percent by volume synthetic extreme pressure anti-wear liquid oil, and about zero to one percent by volume optical brightener.
Abstract:
A grease composition having a base oil and a thickener, which grease additionally has from 0.05% to 30% by weight of sodium thiosulphate and at least 0.1% by weight of one or more additives selected from the group of: calcium salicylate, magnesium salicylate, calcium phenate, and calcium sulphonate, based on the total grease composition, and use of the grease composition to improve rust prevention and abrasion resistance. The invention also relates to a method for preparing the grease composition.
Abstract:
A circuit breaker which is excellent in heat resistance and oxidation resistance in lubricating an open/close mechanism and provides an extended, stable operation, and which comprises an open/close mechanism (A) housed in an insulating case (1) and for opening/closing a movable contact (3) from/to a fixed contact (2), an engaging unit (B) engaging with the open/close mechanism (A), and a tripping mechanism (C) for freeing the engagement of the engaging unit (B) when an over-current is detected in a cable way and separating the movable contact (3) from the fixed contact (2), wherein a part of the open/close mechanism (A) is formed of a material containing iron or iron compound, and its sliding portion is provided with a lubricating oil formed by adding 1 to 5wt.% of molybdenum disulfide to an oxidation inhibitor-added phenyl ether oil.
Abstract:
An aqueous lubricant for use in plastic working of a metallic material which comprises (A) a water soluble inorganic salt and (B) a wax, wherein the components are dissolved or dispersed in water, and wherein a solid concentration ratio (weight ratio) (B)/(A) is 0.3 to 1.5; and a method for forming a lubricant film, characterized in that a lubricant film is formed by applying the aqueous lubricant, preferably in a dried weight of 0.5 to 40 g/m , on the surface of a metallic material having no chemical film formed thereon, followed by drying. The aqueous lubricant preferably further comprises (C) a metal salt of a fatty acid in a solid concentration ratio (C)/(A) of 0.01 to 0.4. The water soluble inorganic salt(A) is preferably selected from among a sulfate, a silicate, a borate, a molybdate and a tungstate. The wax is preferably a natural wax or a synthetic wax which is dispersed in water and has a melting point of 70 to 150 DEG . The metal salt of a fatty acid (C) is preferably obtained through reacting a saturated fatty acid having 12 to 26 carbon atoms with a metal selected from among zinc, calcium, barium, aluminum, magnesium and lithium. The aqueous lubricant can be used for imparting excellent bubricity with ease to the surface of a metal having no chemical film formed thereon.
