Want this question answered?
electrons can flow through circuits.
Yes . Some insulators do allow the flow of electrons but most do not.
elelctric current
When electrons flow through a conductor such as a wire, it is called, "Electricity".
The flow of electrons from atom to atom is an electrical current.
Cathodic protection is a way of preventing or controlling corrosion of a metal structure.
Cathodic protection survey is a method used to assess the effectiveness of cathodic protection systems on buried or submerged metal structures like pipelines or storage tanks. It involves measurements of electrical potentials, current flow, and other relevant parameters to ensure that adequate protection is being provided to prevent corrosion and extend the lifespan of the structure. The survey results help in identifying any issues or areas that may require maintenance or improvements in the cathodic protection system.
Cathodic protection is used to control corrosion of metal on the surface of structures in various environments. In some cases Cathodic protection can prevent stress corrosion and fracturing.
The KKS system is a standardized system for the classification of technical equipment in power plants. It does not specifically address cathodic protection systems. Cathodic protection systems are typically classified based on their method (e.g., impressed current or sacrificial anode) and location within the power plant.

Coatings Cathodic Protection If steel- galvanizing
Good design Proper material selection coatings including metal coatings and paints Impressed Current Cathodic Protection Sacrificial Anode Cathodic Protection Anodic Protection Combinations - especially use of CP and coatings
aluminum, platinum, carbon & silicon
Cathodic protection - attach a piece of zinc Cathodic protection - pass electric current through it - take care this is an industrial method only for protecting pipelines etc. Galvanizing Painting Wax/oil/grease
Taken from Introduction To Corrosion Science by E. McCafferty Two notable things occur during a cathodic reaction. 1.) A given species undergoes reduction (there is a decrease in its oxidation number) 2.) A gain of electrons at the cathodic site (electrons are consumed by the reaction) An example of a cathodic reaction is: 2H+(aq) + 2e- ==> H2(g) This reaction however is just a half-cell reaction, which means it is usually coupled (happens along with) an anodic reaction.
The deflection of cathodic rays was the source of inspiration for Thomson.
