Abstract: Iron-based metallurgical powder compositions are produced by mixing iron-based powder with an improved binder/lubricant that comprises dibasic organic acid and one or more additional components such as solid polyethers, liquid polyethers, and acrylic resin. These novel binder/lubricants impart one or more enhanced green properties to the powder compositions and reduce the ejection force required to remove the compositions from molds and dies.

Abstract: A machining oil composition comprises at least two ingredients, that is a lubricating base oil and a salt selected from sulfonates of alkali metals and the like. The composition may further comprise a metal composition selected from thiophosphates and the like, and/or sulfur-based extreme pressure agents. Since no chlorine-based extreme pressure agent is contained, little problem on the environmental pollution or the damage of incinerators is involved. The composition exhibits good machining or cutting performance.

Abstract: A graphite-free lubricating oil which comprises a base oil having dispersed therein 10 to 40% by weight of a carbohydrate and/or a derivative thereof whose particle size ranges from 10 to 150 µm, 2 to 20% by weight of a film-boosting agent and 0.1 to 20% by weight of a dispersant. Moreover, the lubricating oil is free of black-colored substances such as graphite. Therefore, the oil permits the improvement of working surroundings and exhibits excellent properties such as formability through forging almost comparable to or even greater than that of the commercially available graphite-in-oil type lubricating oils. The lubricating oil can be used instead of the graphite-containing lubricating oils for warm forging, hot forging, rolling, tube-manufacturing, drawing and extrusion in place of the graphite-containing lubricating oils and ensures the improvement in the working surroundings and excellent lubricity.
Abstract translation: 一种无石墨的润滑油,其包含分散有10〜40重量%的碳水化合物和/或其衍生物的基础油,其粒度范围为10〜150μm,2〜20重量% 增压剂和0.1〜20重量%的分散剂。 此外,润滑油不含石墨等黑色物质。 因此,油可以改善工作环境,并且通过与几乎相当于或甚至大于商业上可获得的油包油型润滑油的锻造而通过锻造显示出优异的性能,例如锻造成形性。 可以使用润滑油代替用于温锻,热锻,轧制,管制造,拉伸和挤出的含石墨的润滑油代替含石墨的润滑油,并确保工作环境的改善和优异的润滑性 。

Abstract: A halogen-free lubricant additive composition is disclosed which comprises the reaction product of elemental sulfur, an olefin, and an aqueous solution of an alkali metal or alkaline earth metal salt of hydrosulfide. The reaction product has been found to contain little or no dithiolethiones and is useful as an extreme pressure/antiwear additive for motor fuels, as well as lubricants such as mineral- and synthetic-based oils and greases.

Abstract: Lubricant compositions, especially suitable as gear oils, containing sulphur-containing extreme pressure or anti-wear agents, are improved by incorporation of an oil-soluble salt of an amine and a weak acid or amino acid. The resulting compositions confer extended life on gears operated in them.
