Pulse current

from Wikipedia, the free encyclopedia

Pulse current is generated by pulse rectifiers or potentiostats or galvanostats . Pulse current consists of individual pulse sequences that can be anodic as well as cathodic currents and also contain pulse pauses. It can be used for the electrolytic deposition ( electrolysis ) of metals . Deposition with pulsed currents is a further development of the direct current method. From the fact that deposition requires cathodic currents, it follows that the cathodic portion of the pulses predominates during deposition. Pulsed currents can also be used for electrochemical removal. In these cases the anodic current component predominates. Such methods can be used for electropolishing. A wide variety of pulse shapes are used. Among other things, rectangular pulses are used. In this case, the description is made, among other things, by pulse current strength or pulse voltage, pulse duration or Pulse rate.
