Self-lubricating effect

Development and tribological evaluation of these self-lubricating composites over the past several years has recently been reviewed by Sutor and Gardos (7, 8). This work demonstrated that many of the composites which were excellent lubricants for steel were poor lubricants for silicon nitride. Thus, achieving effective solid lubrication of silicon nitride was of particular concern. 

Rubbing of polyarylene etheroketone (PAEK) containing ether links in its backbone chain, a carbonyl group and aromatic nuclei is accompanied by destruction along mainly ether links and structuring processes. Formation of stable transfer films on the steel counterbody leads to friction between polymer layers with the effect of self-lubrication that lowers the friction coefficient and heightens wear resistance of PAEK as compared to PPO [99]. 

INHAM materials are related to self-lubricating antifrictional composites intended for friction parts experiencing the effect of harsh liquid media.

Frictional effects of PDMS sliding on gold surfaces,glass, silicon oxide surfaces, or glassy polymers, have been investigated in detail. There has also been some interest in self-lubricating biomaterials. -... 

The development of a graphitic film on the mating surface is a basic requirement for effective self-lubrication by mechanical carbons. In the absence of adsorbed moisture or vapors on carbon, or of the oxide films that are usually present on metal surfaces, the required graphitic film may not be established...
