Abstract: Electrodes for electrochemical processes, especially anodes for the cathodic protection of metal substrates, e.g. reinforcing bars in concrete, comprise a conductive core which acts as a current-distributing member, an outer member which provides an electrochemically active outer surface, and an intermediate member composed of a material which is of higher resistivity, and/or which is less electrochemically active, than the material of the outer member. The higher the resistivity of the intermediate member, the more regular the current distribution along the length of the electrode. When the intermediate member is less electrochemically active, this protects the core from corrosion if the outer member is damaged by physical means or through electrochemical erosion. Preferably at least one of the intermediate member and the outer member is composed of a conductive polymer, especially one comprising carbon black or graphite as conductive filler.

Abstract: Disclosed are improved compositions useful in providing a conductive layer or coating on or within a substrate. The compositions contain elemental carbon and a polymeric matrix or binder. The improvement comprises employing a unique ground calcined, coal-based coke which approaches graphite in terms of its performance as a conductive additive or pigment but does not possess the disadvantages associated with the use of graphite.The unique coke employed in the compositions and methods of the present invention has a significant level of graphitic structure. This level of graphitization can be most easily recognized by utilizing x-ray powder diffraction. More specifically, when the value of E.sub.c, or the inverse peak width (of the 002 peak), is measured for this material using Mo K.alpha. radiation (.lambda.=0.71 .ANG.), the value is in the range of about 27 to about 80, and preferably about 28 to about 75.The final compositions employ a polymer resin or matrix system as a binder which, when allowed to dry or cure, in situ, is water-permeable. They are useful as cathodic protection coatings for concrete and other building materials which are reinforced with low carbon steels and the like.The invention also relates to the method of applying the compositions to the reinforced substrate, and the resulting coated articles.
