Effect of black phosphorus modified by fullerene C60 on the self-lubricating properties of PEEK-based composite coatings

Poly-ether-ether-ketone (PEEK) has many excellent properties for being used as self-lubricating coatings. In order to further improve the friction performance, black phosphorus (BP) was used as filler to prepare BP/PEEK composite coating . BP-C 60 was formed by modification of BP edge by fullerene C 60 to solve the problem of BP oxidation , so that BP still existed in the sintered PEEK coating. Then, the effects of C 60 and BP-C 60 on the tribological properties of PEEK coating were studied, and the results showed that the wear rate and friction coefficient of BP-C 60 /C 60 /PEEK composite coating were significantly reduced. This was attributed to the synergistic effect of BP and C 60 , which enhanced the stability of BP and reduced coating porosity.
