AMPP CIP Level 1 Theory Questions and Answers 2024
What is corrosion? - Correct Answer - The deterioration of a metal or alloy that results from an electrochemical reaction with its environment.
What needs to be present in order for corrosion to occur? - Correct Answer - Anode
Cathode
Metallic Pathway
Electrolyte
What is an anode? - Correct Answer - The anode is the area of the metal surface that corrodes. The metal oxidizes (gains oxygen), causing it to lose mass and dissolve into the electrolyte.
What is oxidation? - Correct Answer - Oxidation is a chemical reaction that occurs at the anode where the metal loses electrons.
What is a cathode? - Correct Answer - The cathode is the area of the metal surface that reduces (loses oxygen).
What is reduction? - Correct Answer - Reduction is a chemical reaction that occurs at the cathode that involves the metal gaining electrons.
What is the metallic pathway? - Correct Answer - The metallic pathway connects the anode to the cathode and allows the passage of electrons generated from the cathode to the anode.
What is an electrolyte? - Correct Answer - The electrolyte is the conductive medium (any solution, like water) in which ions are carried from the anode to the cathode.
What is a barrier coating? - Correct Answer - A barrier coating protects the substrate/metal by providing
a chemical and physical barrier between the metal surface and the environment. The barrier coating interrupts the electrolyte of the electrochemical cell.
What is passivation? - Correct Answer - Passivation is when a layer of oxides form on the surface of a metal that provides corrosion protection.
What is the purpose of the electrolyte? - Correct Answer - To allow the passage of ions from the anode to the cathode. What is a sacrificial coating? - Correct Answer - A sacrificial coating is a coating that contains a metal (usually zinc) that will corrode instead of the metal substrate.
What is an inhibitive coating? - Correct Answer - Inhibitive coatings act as aa barricade to slow down the
reaction at the anode, or cathode, or both. They contain special pigments that react with moisture or oxygen and form a hard, non-reactive surface film that interferes with the corrosion process.
What are the 4 basic components of a coating? - Correct Answer - Pigments
Binder/Resins
Solvents
Additives
What is are pigments? - Correct Answer - Pigments are the solid particles that give specific protective, mechanical, or decorative qualities to the coating. In its unmixed form, pigments are powders.
What are binders/resins? - Correct Answer - Binders/resins are liquids that adhere to the substrate and chemically change (cure) to form a hard, protective film.
What are solvents? - Correct Answer - Solvents are the liquid components of the coating that are responsible for dissolving the solid binder/resin.
What are additives? - Correct Answer - Additives are special ingredients used to enhance the performance or certain properties or characteristics of coatings. They are commonly liquid components that are added in small amounts.
Which 3 materials are commonly used as galvanic anodes for carbon steel? - Correct Answer - Zinc
Magnesium
Aluminum
How does high or low temperature affect the corrosion rate? - Correct Answer - High temp = corrosion rate increases
Low temp = corrosion rate decreases
