The wear of friction pairs, especially under current-carrying conditions, significantly reduces equipment per
formance and service life due to electric arc erosion. This study employs laser surface texturing on copper blocks
to create microporous structures, with polyaniline grease synthesized in situ based on these microscale reactors
to reduce material wear and arc erosion. Results demonstrate that this method effectively fills the microporous
with grease, ensuring grease supply under starved lubrication and long-term stable operation of friction pairs.
The textured sample with a diameter of 140 µm at 6 A exhibits a 74.3 % reduction in coefficient of friction, 2.7
times less wear, extremely low arc erosion, and an electrical contact resistance of only 2.5 mΩ, maintaining
stable tribological performance even after 21,600 cycles.
