Abstract

A composition for prevention or reduction of fatigue damage, especially trench formation or micropitting, of the surfaces of drive elements, is provided that comprises 0.1 to 40% by weight of surface-modified nanoparticles, and 99.9 to 60% by weight of a carrier material suitable for application to the drive element surfaces.
