Cathodic Protection—What is it? How Does it Work? | MATCOR
Cathodic protection (CP) is an electro-chemical process that slows or stops corrosion currents by applying DC current to a metal. When applied properly, CP stops the corrosion reaction from occurring to protect the integrity of metallic structures. MATCOR's Ted Huck is "YouTube Famous" for his explanation of cathodic protection in this ...

Cathodic protection - Wikipedia
Cathodic protection (CP; / k æ ˈ θ ɒ d ɪ k / ⓘ) is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. A simple method of protection connects the metal to be protected to a more easily corroded "sacrificial metal" to act as the anode. The sacrificial metal then corrodes ...

Degradation of phenol in wastewater by the cathodic and anodic ...
Reverse electrodialysis reactor (REDR) can convert the concentration gradient energy of the working fluids into the degradation energy of organic matters in wastewater. In order to verify this energy conversion process, the experiments on the degradation of phenol wastewater in the cathodic and anodic independent loops of REDR powered by concentration gradient energy were conducted.

意义和目的. 4.1 Damage to pipe coatings is almost inevitable during transportation and construction. A break or breach in the pipe coating may expose the pipe to corrosion because after the pipe is installed underground, the surrounding soil will contain moisture and constitute effective electrolytes.

DCVG
As pipelines age coatings deteriorate and the cathodic protection becomes increasingly important in mitigating corrosion damage. In addition, the cathodic protection is switched on and off repeatedly using an electronic switch commonly referred to as an interrupter.
