Protection by impressed currentThe electrical current is generally provided by a transformer-rectifier and its negative pole is connected to the...
The cathodic protection of buried structures can be obtained by galvanic anodes but more generally by impressed current. In all cases the anodes are...
The buried works to which cathodic protection can be applied are pipes (gas, oil, water), buried tanks, well linings, lower parts of aerial tanks and...
Types of structures to be protectedDesignImplementationMonitoring and control
The aim of the cathodic protection systems design is to define the number, the mass, sizes and the distribution of the anodes in order to be sure...
A cathodic protection installation muste be regularly monitored and controlled to make sure the protection is efficient. Level of...
Galvanic cathodic protectionSome metals or alloys placed in the same electrolytic environment as the structure to be protected have an electrode...
Cathodic protection is a technique enabling to reduce the corrosion rate of a metallic material, in an aqueous environment, by decreasing the...
Normal hydrogen electrode (NHE)In electrochemistry, the standard hydrogen electrode (SHE) is the absolute reference electrode; its potential is...
The corrosion of metallic materials at ambient or relatively low temperature is mainly due to liquid water coming to their contact. The aqueous phase...
