Publisher Summary Cathodic protection is used in hazardous locations to prevent corrosion in tanks, pipelines, and other associated equipments. It has proven to be unsafe with respect to sparking, and is dangerous in the neighborhood of flammable vapors. Double ground an equipment in a hazardous area with cathodic protection.

Publisher Summary This chapter presents a discussion of Cathodic Protection (CP) systems and their design. It begins with an introduction to corrosion fundamentals and CP principles. Cathodic protection is a thermodynamic means of controlling the rate of corrosion and can be applied either by electrically coupling the metal to more reactive metal that

Small, 2018
The development of manganese dioxide as the cathode for aqueous Zn-ion battery (ZIB) is limited by the rapid capacity fading and material dissolution. Here, a highly reversible aqueous ZIB using graphene scroll-coated α-MnO2 as the cathode is proposed ...

A cathode spot vacuum arc with graphite cathode
Proceedings ISDEIV. 18th International Symposium on Discharges and Electrical Insulation in Vacuum (Cat. No.98CH36073), 2002A theoretical study of near-electrode processes on graphite cathodes is presented. A physical model based on the kinetic treatment of cathode evaporation and electron emission from the cathode, as well as plasma production, is developed. A system of equations for calculating the electrode erosion rate and cathode potential drop as well the cathode ...

Cathodic etching in a penning cold cathode discharge
Vacuum, 1959Abstract An apparatus for cathodic etching using a Penning cold cathode discharge is described. One of the twin cathodes is the specimen to be etched whilst the other is made of aluminium. The cathodes are water cooled so that metals of either low melting point or low sputtering rate will not overheat during the cathodic etching.

Layered MgxV2O5·nH2O as Cathode Material for High-Performance Aqueous Zinc Ion Batteries
ACS Energy Letters, 2018The performance of chemically intercalated V2O5 was found to strongly depend on the interlayer spacing, which is related to the radius of hydrated metal ion, which can be readily tuned by using different intercalated metals.

Highly Durable Na2V6O16·1.63H2O Nanowire Cathode for Aqueous Zinc-Ion Battery.
Nano letters (Print), 2018Rechargeable aqueous zinc-ion batteries are highly desirable for grid-scale applications due to their low cost and high safety; however, the poor cycling stability hinders their widespread application.

Cathode spot development on a bulk cathode in a vacuum arc
2012 25th International Symposium on Discharges and Electrical Insulation in Vacuum (ISDEIV), 2012This work considers transient spot development on a bulk cathode, taking into account the initial adjacent plasma generated during arc triggering. A self-consistent model was developed to describe the transient cathode phenomena and the time dependent cathode potential drop, taking into account the kinetics and gasdynamics of cathode plasma flow.
