摘要：

ECM simulation tests and the technological experiments using a permanent magnet on the machine tool have been undertaken. Due to the extra energy provided by the magnetic field, the critical voltage decreases with the increase the probability for the particles to be excited to higher energy level from the ground state. The electric fluxes tend to converge as a result of the alignment and precession of magnetic moments of the ions. It follows that dispersion corrosions in ECM are reduced by the properly designed magnetic field. The theoretical analysis of the mechanism reaches good agreement with the experimental data.
