Cathodic Protection QC Course & Interview Questions CP

1. What is ANODE?
 Is an electrode through which positive electric charge flows into a polarized electrical device
2. What is CATHODE?
 Is the electrode from which a conventional current leaves a polarized electrical device, Cathode polarity with respect to the anode can be positive or negative it depends on how the device will operate. (The Current flow of this device are Leaving (-) and Approaching (+).) (Binomial Characteristics)
3. What is ELECTROLYTE?
 Is a Liquid or corrosive, medium that conducts electricity, It contains ions, which are particles of matter that carry a positive or negative charge
4. What is CATHODIC PROTECTION?
 It is a method of protection in iron and steel for electrochemical corrosion
5. What is CORROSION INHIBITOR?

 Is a substantial equipment that, when added to an environment, decreases the rate of attack by that environment. And are commonly added in small amount to acids, cooling waters, steam and other environments
6. What is ICCP?
 Impressed Current Cathodic Protection, it provides an electrical current source to oppose the current of the corrosion cell(s)
