Adhesion enhancement compositions

A composition for increasing adhesion between two surfaces that are in traction, sliding or rolling-sliding contact with each other, the composition consisting of:

• (a) one or more than one first component, each of the one or more than one first component having a Mohs hardness value of equal to or greater than 7, or a Vickers hardness of greater than or equal to 1000, wherein the one or more than one first component is selected from the group of carbide based compounds, amphoteric oxide based compounds, zirconium oxide based compounds, a mineral compound, boron carbide, boron nitride, diamond, nanocrystalline diamond, fullerite, polymerized C60, garnet, topaz, crystalline silica (sand), and any combination thereof;
• and
• (b) an organic rheology additive, wherein the organic rheology additive is a xanthan gum,
• wherein the one or more than one first component is present in an amount from 90% to 99.9% (wt/wt) and the organic rheology additive is present in an amount from 10% to 0.1% (wt/wt), and
• wherein the composition is a powder form.
