ELECTRODES WITH MECHANICALLY COARSENED SURFACE FOR ELECTROCHEMICAL APPLICATION Russian patent published in 2012 - IPC B21B1/22

Abstract RU 2466805 C2

FIELD: machine building.

SUBSTANCE: mechanical coarsening is reached by pinch rolling between two mill rolls, at least one of them has a pattern corresponding to desired profile transferred to metal sheet surface by pressing.

EFFECT: simplifying production of metal sheet with desired highly reproducible roughness pattern, possibility of easy production of coarsened metal sheets with equivalent roughness pattern upon metal sheet passing through working rolls with a certain pattern of texturised surface in one roll mill, enhancing electrochemical performance characteristics of gas-evolving electrode.
