Self-adaptive low friction coatings based on transition metal dichalcogenides

Significance of output:

In this invited paper we present our design of novel self-lubricant coatings with adaptive nanostructure based on transition metal dichalcogenides (TMD). We showed three different systems – nanostructured films, amorphous films, and fullerene-like nanoparticles (IFNP) embedded into hard matrix. All three systems have been prepared for the first time. The nanostructured films clearly outperformed existing coatings based on TMD, since they performed well in humid air. Amorphous WSN film showed one of the lowest friction coefficient ever observed in dry nitrogen (<0.002) due to formation of thin crystalline tribolayer. Contrary to theoretical predictions, IFNP failed to produce low-friction interlayer.
