Abstract:
본 발명에 따른 방법에 따라서 플라스틱슬라이드층의 제조를 위해 무엇보다도 페이스트가 플라스틱분산물과 충진재로부터 만들어진다. 상기 페이스트는 유기용매를 포함하지 않으며, 소결된 다공성 금속층에 도포된다. 생산된 다층재료는 그다음 소결된다. 유기용매가 사용되지 않으므로 건강상의 위험과 화재의 위험이 경감된다. 더구나 본 발명에 따라 제조된 복합재료는 뛰어난 공동화 내성을 보인다. 베어링과 같이 종래의 윤활제가 없는 적용에 추가하여 이들 복합재료들은 특히 기어펌프 및 충격흡수기에서 결과적으로 사용될 수 있다.
Abstract:
A wire rod is payed out from a pay-off stand and descaled in a descaling process. After preheating to a predetermined temperature by a preheating device, it is subjected to a lubrication pretreatment through a zinc calcium phosphate solution applied with ultrasonic wave in the lubrication pretreatment process. After rinsing process, the lubrication-pretreated wire rod is coated with a calcium stearate or a sodium stearate in lubricating process. Thereafter, the wire rod is dried sufficiently in drying process, and then added with a predies lubricant in wire drawing process and coiled by a coiler.

Abstract:
Lubricating compositions for use in the casting of steel, in particular in continuous casting processes are provided. Methods for making and using such compositions are also provided.
Abstract:
Provided is a method for producing a seamless tube, in which after a starting material to be extruded has been heated to a heating temperature T [° C.] satisfying the relationship of Formula (1) or Formula (2) depending on the outside diameter d0 [mm] thereof, the starting material is hot extruded by providing a solid lubricating glass between the starting material to be extruded and a die, whereby a transverse flaw on the outer surface in the top portion of tube can be prevented when hot extrusion is performed by using a starting material for extrusion having low deformability at high temperatures. When d0
Abstract:
The present invention provides a new composite material comprising a porous matrix made of metal, metal alloy or semiconducting material and hollow fullerene-like nanoparticles of a metal chalcogenide compound or mixture of such compounds. The composite material is characterized by having a porosity between about 10% and about 40%. The amount of the hallow nanoparticles in the composite material is 1-20 wt. %.
Abstract:
Dry film lubricant coatings are provided by using a silicone resin binder, either as an aqueous emulsion or in a solvent-based system, to fix an alkaline earth metal fluoride to a substrate. The compositions used to apply the coatings may also include relatively minor amounts of xylene, ammonium benzoate, a wetting agent, and/or a porosity-inducing agent—although none of those additives remains in the cured coating. Multi-layer dry film lubricant coatings are also disclosed, with the multi-layer coating having a basecoat layer as described above, and a topcoat layer made of a layer-lattice solid such as graphite or molybdenum disulfide, and a silicone resin, aluminum phosphate or an alkali metal silicate binder.
