A low friction wear surface with a coefficient of friction in the superlubric regime under a sliding and rolling movement. The low friction wear surface includes molybdenum disulfide and graphene oxide on a first wear surface with a tribolayer formed on a rough steel counter surface during the sliding and rolling movement. Methods of producing the low friction wear surface are also provided.

A bearing assembly is disclosed that includes a first component with a first bearing surface, and a second component with a second bearing surface. A fluid is disposed between the first bearing surface and the second bearing surface supporting the first bearing surface and the second bearing surface in a non-contact rotational relationship. The first bearing surface, or the second bearing surface, or both the first bearing surface and the second bearing surface include a surface layer with solid lubricant 2D nanoparticles in a matrix.

A lubricating composition which, when used with a device for clamping an article, such as a chuck, produces excellent lubricating properties whilst remaining strongly adhered to metal parts in a clamping mechanism of the device and showing enhanced chemical and physical resistance to fluids such as cutting fluids.

[Object] An object of the present invention is to provide a high-aspect-ratio plate-like alumina particle having low aggregability and high dispersibility and a method for producing the particle. [Solving Means] The above problem is solved by providing a plate-like alumina particle including a step of firing an aluminum compound in the presence of a shape-controlling agent and a molybdenum compound serving as a fluxing agent. The above problem is solved also by providing a method for producing a plate-like alumina particle, the method including a step in which the aluminum compound and the molybdenum compound react with each other to form aluminum molybdate and a step in which the aluminum molybdate is decomposed to obtain the plate-like alumina particle.

Described herein is a stabilized lubricant composition for use in steel casting, in particular in continuous casting processes. In particular, the lubricant composition for processes for producing steel by continuous casting includes a dispersion of a lubricant powder, for an ingot mold, in continuous casting, in an oily liquid means, and a stabilization additive, characterized in that it has the following shear thinning index values: TABLE-US-00001 RVT 0.1/1 1/10 10/100 100/1000 STI 3.0-7.5 2.0-6.5 1.0-3.0 0.5-2.0 wherein RVT is the ratio between two different shear speeds and STI is the shear thinning index corresponding to the RVT values.
