cathodic

Pertaining to reduction

Cathodic relates to the cathode—the negatively charged electrode in an electrochemical cell.

The term appears most often in cathodic protection, a technique that prevents metal corrosion by making the protected surface act as a cathode: The pipeline uses cathodic protection to resist rust.
