The paper reports the operando and self-healing formation of DLC films at sliding contact surfaces by the
addition of synthetic magnesium silicon hydroxide (MSH) nanoparticles to base oil. The formation of such films
leads to a reduction of the coefficient of friction by nearly an order of magnitude and substantially reduces wear
losses. The ultralow friction layer characterized by transmission electron microscope (TEM), electron energy
loss spectroscopy (EELS), and Raman spectroscopy consists of amorphous DLC containing SiOx that forms in a
continuous and self-repairing manner during operation. This environmentally benign and simple approach
offers promise for significant advances in lubrication and reduced energy losses in engines and other mechanical
systems.
