cathode polarization造句怎么写

The cathode polarization: dc through electrode, the cathode potential deviating from the balance to the negative potential moves in the direction of the phenomenon.

Along with the increase of the current density, cathode polarization effect, coating grain with increasing more and fine.

Experiment results indicated that rare earth could improve the hardness of bright nickel plating, the cathode polarization ability, the substrate bond strength and the grinding ratios of diamond tool.

When the current density is too low, the cathode polarization effect, smaller coating, not even orange crystal Bulky coating.

But can't think that the larger the cathode polarization effect the better.

Practice shows that improve the metal electrical crystallization in the cathode polarization effect, can improve the generation of the nucleation rate, easy to get crystallization meticulous coating.
