Kathodischer

Kathodischer is a German adjective meaning cathodic, relating to the cathode, the electrode at which reduction occurs in electrochemical cells and electrolysis. The term is used across disciplines such as electrochemistry, corrosion science, materials science, and semiconductor processing to describe processes, reactions, or properties associated with the cathode. It contrasts with anodisch or anodic, which pertain to the anode.

In general usage, kathodischer describes phenomena that occur at the cathode. For example, kathodische Abscheidung refers to cathodic deposition—electrodeposition of material onto a cathode during electroplating or related processes. Kathodischer Schutz, or cathodic protection, is a widely used method to prevent metal corrosion by making the protected structure act as a cathode in a galvanic cell or by applying an external current.

Cathodische Prozesse typically involve reduction reactions, such as metal ion deposition or hydrogen evolution, depending on the electrolyte, electrode materials, and applied potential. These processes are fundamental in manufacturing and maintenance contexts, including corrosion control, electroplating, and thin-film or vacuum deposition techniques where cathodic deposition or sputtering plays a role.

The term is often encountered alongside its counterpart anodisch, which describes oxidation processes at the anode. In technical writing and practical applications, kathodischer is used to specify that a described process, reaction, or property is associated with the cathode side of an electrochemical system. In English literature, the equivalent term is cathodic.
