Overvoltage
Overvoltage in relation to electrolysis and electroplating is a phenomenon that occurs in electrochemical processes. Electrolysis is a process in which chemical reactions are induced by applying an electrical voltage to an electrolyte solution. In electroplating, the electrochemical deposition of metal layers on a substrate is carried out.
The overvoltage is an additional electrical input that is required to cause the transfer of an electron or ion at the electrode. In electrolysis and electroplating, overvoltage can be undesirable as it can lead to higher energy consumption and inefficient processes.
Various measures can be taken to minimize the overvoltage, such as selecting suitable electrode materials, optimizing the electrolyte composition or adjusting the process parameters. This helps to improve the energy efficiency of electrolysis and electroplating processes.
Knowledge and control of overvoltage is particularly important in areas such as surface technology, electrochemistry and metal processing, where electrochemical processes are used. Through targeted optimization, companies can not only reduce energy costs, but also improve the quality and efficiency of their electroplating products.
