anodeThe positive electrode in an electrolytic cell (see electrolysis), thermionic valve, cathode ray tube, or similar device, towards which negative particles are attracted. The negative particles originate from the cathode. In these cases the flow of electrons is out of the device at the anode. The term is also inconsistently applied in some other cases to electrodes at which the flow of electrons is into the device – for example, to the positive terminal of a battery.

The homopolymer PVdF is highly anodically stable owing to its strong electron with drawing functional groups (--C--F) and high dielectric constant ([epsilon] = 8. After the sensor is installed over an inspection area, the steel in the area becomes anodically polarised, creating oxidisation--a passive film on the surface. In zinc-rich primers, zinc is used to produce an anodically active coating. |
