For example, mechanical tunnel driving with boring machines, problem is due excavated material, which sticks metallic parts machine, requiring cleaning, in turn causes delays financial losses. article suggests a method reduce adhesion material on steel surface means electro-osmosis. The different types metal was studied tilted plate tests. Three samples were compacted cut into slices thickness 1 cm. Afterwards, both direct current (DC) pulsating DC, consisted positive half-cycle only, applied order study influence electro-osmosis adhesion. application electrical fields caused detachment clays from slight shear forces. It not currently possible determine DC or behavior because complexity system. However, use results lower contact impedance. reduced impedance higher currents (for same potential difference) thus electro-osmotic efficiency (i.e., energy needed detach significantly than DC). sample impedances determined spectroscopy measurements.
