Name the principle used in electroplating
Electropolishing, also known as electrochemical polishing, anodic polishing, or electrolytic polishing (especially in the metallography field), is an electrochemical process that removes material from a metallic workpiece, reducing the surface roughness by levelling micro-peaks and valleys, improving the surface finish. Electropolishing is often compared to, but distinctly different from, electrochemical machining. It is used to polish, passivate, and deburr metal parts. It is often descr… Witrynathe more common ones currently used in plating. Clearly, there are numerous parameters and resulting methods of application of pulse signals to electroplating. Many applications of pulse plating have been unsuccessful because of the lack of setting up the appropriate parameters: waveform, duty cycle, frequency and amplitude. Care should …
