潤滑組成物及びその調製方法

Japanese Patent JP5739012

B2

The invention relates to lubricating compositions and methods for producing same. The lubricating composition comprises a lubricating medium and the product of dehydration of natural minerals or a mixture of natural minerals, or of synthesized hydrates. The dehydration product contains the oxides MgO and/or SiO 2 and/or Al 2 O 3 and/or CaO and/or Fe 2 O 3 and/or K 2 O and/or Na 2 O and has a particle size in a range of 100-100000 nm. The method for producing the lubricating composition comprises a step in which hydrates of metal and/or non-metal oxides are dehydrated at a temperature of from 300 to 1200°C, a step in which the dehydration product is stabilized by being kept at a temperature of from 700 to 1200°C for a period of 1 to 3 hours, and a step in which the resultant product is mixed with a lubricating medium. The resultant lubricating composition not only aids in reducing loads on friction surfaces, but also is capable of performing the function of strengthening friction surfaces as a result of the plastic deformation of the metal in nanovolumes and the surface layer being brought into an active nanostructured state, said surface layer thus being strengthened. At the same time, the grains of the metal undergo intensive fragmentation, the density of the grain boundaries is increased, and the conditions for the diffusion of carbon deep into the surface (vertically) and into the grains (horizontally) are improved.
