“There is a sucker born every minute” is a statement attributed to P.T. Barnum of circus fame who also opined that “Every crowd has a silver lining.” This apparent truism has encouraged all kinds of grifters, con men, and others scoundrels to devise schemes to […]
Magnetism and magnetic effects are know to nearly everyone but the explanation of how magnetism behaves can be very complicated. This presentation will attempt to simplify magnetic theory to permit the understanding of magnetic fields and their influence on various materials. The nature and strength […]
Elements known to the ancients were given Latin names which were abbreviated. Iron was called Ferrum in Latin which was abbreviated to Fe. Copper was called Cuprum shortened to Cu, etc. More recently discovered elements are usually abbreviated by using the first two letters in […]
It is best to review the differences between these two protection techniques before discussing their application in the Paper Industry. Corrosionists have been aware of the electrochemical nature of aqueous corrosion since the studies of Davy & Faraday. Apart from some early experiments using zinc […]
Cathodic protection is discussed in relation to the likelihood that its application will rest on economic considerations. Various methods are presented from the literature and a case is made for the use of the Equivalent Annual Cost Method together with several illustrations of its use.
Following a short review of corrosion theory, cathodic and anodic protection is described with reference to some practical problems that arise from the application of these techniques.
In a recent editorial m the British Corrosion Journal, they referred to the objection of a councilor on Surrey County Council who objected to the provision of a E 20,000 sterling laboratory to be associated with a new sewage disposal plant. He objected because he […]
