The Permanent Anode in Impressed‐current Cathodic Protection Systems—Part 2

Progress continues in the search for better and more universal permanent anode materials in impressed‐current cathodic protection systems. Last month graphite, silicon iron and scrap steel were discussed in this connection and the concluding part of the article continues by describing the properties, uses and limitations of lead and platinised lead, and platinised titanium. The fundamental principles of connection are also covered.
