Englisch - Englisch
An electrical system for prevention of rust, corrosion, and pitting of metal surfaces which are in contact with water or soil
method of preventing corrosion of iron or steel by suspending stainless steel anodes in the tank and passing a small current continuously through the system
a means of corrosion prevention whereby electrons are supplied to the structure to be protected from an external source such as anoother more reactive metal or a dc power supply
The process in which a structural metal, such as iron, is protected from corrosion by connecting it to a metal that has a more negative reduction potential
A method of preventing oxidation (rusting) of exposed metal structures, such as bridges and pipelines, by imposing between the structure and the ground a small electrical voltage that opposes the flow of electrons and that is greater than the voltage present during oxidation
a method in which an active metal, such as magnesium, is connected to steel in order to protect it from corrosion
Placing a more reactive piece of metal in contact with a metal to prevent rusting The more reactive metal is a sacrificial (anode) electrode
any one of several methods for protecting underground tanks and pipelines from corrosion Corrosion results from an electric current which is caused by contact between metal surfaces, water, and the chemicals present in soils and water; cathodic protection counteracts this current
The process in which a structural metal, such as iron, is protected from corrosion by connecting it to a metal that has a more negative reduction half-cell potential
Reducing the corrosion of a metal by making the particular surface a cathode of an electrochemical cell
An electrical system for prevention of rust, corrosion, and pitting of metal surfaces which are in contact with water or soil A low-voltage current is made to flow through a liquid (water) or a soil in contact with the metal in such a manner that the external electromotive force renders the metal structure cathodic This concentrates corrosion on auxiliary anodic parts which are deliberately allowed to corrode instead of letting the structure corrode
prevents corrosion An electric current is passed through an electrolyte to a metal surface This process can check or completely prevent practically every corrosion process
a more active metal is placed next to a less active metal The more active metal will serve as an anode and will be corroded instead of the less active metal The anode is then called a sacrificial anode
A technique to prevent corrosion of a metal surface by making it the cathode of an electrochemical cell
A corrosion control system in which the metal to be protected is made to serve as a cathode, either by the deliberate establishment of a galvanic cell or by impressed current (See anode )
Deliberate decrease of the corrosion rate by making the potential of a metal structure immersed in an electrolyte more negative (more cathodic) [back] [top]
A method to prevent oxidation or rusting of exposed metal structures, such as bridges and pipelines, by having a small electrical voltage between the structure and the ground to oppose the flow of electrons
Reduction of corrosion rate by shifting the corrosion potential of the electrode toward a less oxidizing potential by applying an external electromotive force
a means of preventing metal from corroding; this is done by making the metal a cathode through the use of impressed direct current and by attaching a sacrificial anode
