Abstract:
The present invention provides a method of recycling a water-based wire saw cutting slurry waste fluid comprising abrasive particles and waste solids in a water-based carrier. The method comprises the steps of (a) separating the waste fluid into a first fraction and a second fraction, the first fraction comprising recovered abrasive particles, and the second fraction comprising waste solids and a portion of the water-based carrier; (b) optionally, separating the second fraction to separate the waste solids from the water-based carrier to form a waste solids portion and a recovered water-based carrier portion; (c) optionally, drying the first fraction from step (a) and separating the resulting dried abrasive particles from smaller waste particles to produce a purified recovered abrasive fraction; and (d) suspending particles of the first fraction from step (a), the purified recovered abrasive fraction from step (c), or both, in a suspending medium comprising at least a portion of the recovered water-based carrier from step (b), to generate a recycled water-based wire saw cutting slurry.

Abstract:
The invention concerns a powder metal composition comprising an iron based powder and a lubricant and/or binder comprising at least one secondary amide of the general formula: R1—NH—CO—R2, wherein R1 and R2 are the same or different, straight or branched, saturated or unsaturated aliphatic hydrocarbon groups. The invention further concerns a method of making green bodies of the powder metal composition according to the invention, a method of producing a bonded iron-based powder composition, as well as the use of the at least one secondary amide as a lubricating and/or binding agent for iron based powders and the use as a die wall lubricant.
Abstract:
A solid stick composition for use on steel surfaces that are in sliding or rolling-sliding contact. The solid stick composition comprises a vinyl ester resin, for example, from about 20 to about 80 weight percent vinyl ester resin, a solid lubricant, for example from about 0 to about 80 weight percent lubricant, and optionally a friction modifier, for example from about 0 to about 40% weight percent friction modifier, or a combination of a solid lubricant and a friction modifier. The solid stick comprises at least one of the lubricant or the friction modifier. A method of controlling friction between a metal surface and a second metal surface by applying the solid stick composition to one or more than one of the metal surfaces is also disclosed as well as a method of reducing lateral force in a rail system comprising applying the solid stick composition onto a wheel or rail surface.

A double-layer lubrication coating composition is made up of an upper-layer coating composition and a lower-layer coating composition. The upper-layer coating composition is made up of 5o to 70 wt % of an epoxy resin or a polyamide-imide resin, 5 to 20 wt % of boron nitride, and 15 to 30 wt % of silicone nitride or alumina. The lower-layer coating composition is made up of 50 to 70 wt % of an epoxy resin or a polyamide-imide resin, 15 to 30 wt % of polytetrafluoroethylene and 5 to 20 wt % of molybdenum disulfide and may include graphite as required.
Abstract:
A sliding film includes a solid lubricant, a binder resin, and a low-melting-point material. The binder resin is for holding the solid lubricant on a surface of a substrate, and exhibits a glass transition temperature. The low-melting-point material exhibits a melting point lower than the glass transition temperature of the binder resin. The low-melting-point material demonstrates a latent heat which can absorb frictional heat generated between sliding members, and accordingly retards the degradation of the binder resin. As a result, the sliding film produces high seizure resistance.

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.
