METHOD FOR COMPOSING A NANO-PARTICLE METAL TREATMENT COMPOSITION FOR CREATING A CERAMIC-METAL LAYER

A metal treatment composition including Tin (II) Chloride and processed montmorillonite clay. The addition of Tin (II) Chloride to the composition provides Tin for forming a ceramic-metal layer on the surfaces of the friction pair. Tin (II) Chloride provides Chlorine ions for forming Chloric films for protecting juvenile surfaces which form in the friction zone. The clay is heated and pulverized to produce a powder comprising both particles having crystalline layer structure and salts and oxides. The layered crystalline structure of the clay contains slip planes that transversely shift when tangential pressure from the friction pair is applied thereby lubricating the friction pair. The salts and oxides contribute to the formation of the ceramic -metal layer.

There is provided a lubricant for hot plastic working, which contains 20 to 40 mass % of iron oxide and 10 to 30 mass % of sodium silicate, wherein impurities are 3 mass % or less, and the lubricant contains 40 to 60 mass % of water. By virtue of combined action of these components, the lubricant exhibits excellent lubricity and suppliability and does not adversely affect the corrosion resistance of product. The lubricant is suitably used for lubricating a guide shoe in piercing-rolling, for example, a high-Cr steel and achieves a great effect of preventing a seizure flaw from occurring on the outer surface of product by being applied directly to the outer surface of a workpiece just before piercing rolling, preferably, within one second before starting piercing rolling.

СМАЗОЧНАЯ КОМПОЗИЦИЯ И СПОСОБ ЕЁ ПОЛУЧЕНИЯ И ПРИМЕНЕНИЯ

Настоящее изобретение относится к области смазочных материалов и, в частности, описывает смазочную композицию и способ ее приготовления и использования. Смазочная композиция включает базовое масло и диспергированные в нем частицы каучука, имеющего сшитую под действием излучения структуру, причем базовое масло является непрерывной фазой, а частицы каучука являются дисперсной фазой. Вязкость смазочной композиции по настоящему изобретению можно эффективно регулировать при изменении температуры. По сравнению со смазочной композицией, включающей химически сшитые частицы каучука, она имеет более низкую вязкость при низких температурах и более высокую вязкость при высоких температурах и имеет относительно высокий индекс вязкости, что может соответствовать требованиям при применении при температуре выше 200°C. Кроме того, смазочная композиция по настоящему изобретению также имеет отличные противоизносные и антифрикционные свойства. 5 н. и 19 з.п. ф-лы, 4 табл., 14 пр.

Nanoparticle graphite-based minimum quantity lubrication method and composition

A lubricant composition is disclosed that includes (a) a machining oil and (b) an exfoliated graphite nanoparticle (EGN) material stably dispersed in the machining oil. The lubricant composition is a stable suspension and is suitable for use as a liquid lubricant in a Minimum Quantity Lubrication (MQL) process. In the MQL process, the lubricant composition is applied/transferred to a worksite in the form of a mist. The presence of the EGN material in the lubricant composition provides high-temperature stability and lubricity under MQL conditions. A very small amount is transferred especially at high cutting speeds where the mist of the machining oil evaporates, but the EGN material remains on the surface to provide lubricity. Any operation involving machining can benefit from this lubricant composition. The method provides important benefits of reducing chipping on cutting tools and providing the additional lubricity especially when the cutting become very hot and thus extending tool life.
