PLATINUM in ANODES: Cathodic Protection Applications—Part I Available to Purchase

The increasing use of platinum — containing anodes in cathodic protection and the discussions which took place at the recent International Congress on Metallic Corrosion in London, make this subject of topical interest. In this review paper the author provides a balanced overall picture of the various applications in this field. The development, advantages and limitations are described of three types of support for a thin layer of the metal, as well as an alternative use of platinum in the platinum‐lead bi‐electrode. At present only two types of platinum electrode can be widely recommended.
