Define Corrosion: The deterioration of a substance, usually a metal from a reaction with its environment 2. What is passivation?: A layer of oxides formed on the surface of a metal that provides corrosion protection . 3. What is an example of passivation?: Stainless Steel 4. What are the elements of a corrosion cell?: Anode, Cathode, Metallic Pathway, Electrolyte 5. Describe what happens at th e anode .: The metal dissolves into the electrolyte 6. What is the function of the electrolyte?: Allows the passage of ions to connect the corrosion cell 7. What is the function of the metallic pathway?: Allows the flow of electrons to connect the corrosion ce ll 8. What is the galvanic series?: A listing of metals in order of reactivity (more or less noble) in seawater at 25 C . 9. The general rules of galvanic corrosion are:: The less noble (or more reactive) metal when connected to a more noble (or less reactive meta l) will corrode preferentially 10. Name the five most important factors that affect the rate of corrosion.: Humidity, oxygen, chemical salts, pollutants, temperature 11. General corrosion is:: Results in a relatively uniform loss of material over the entire surfac e, Results in a general thinning of the affected surface, Relatively easy to inspect, Does not casue catastrophic failures 12. Localized corrosion is:: Typically pitting and crevice corrosion. It is typically of the most concern as damage is concentrated and l oss of integrity or structural failure can result. 13. List some of the common tools/methods used for corrosion control.: Design, Inhibitors, Material Selection, Cathodic Protection, Protective Coatings, Splash Zone Systems, Alteration of the Environment 14. How does NACE define the inspector's role?: The inspector's role is that of a quality control technician responsible for observing and reporting conformance or deviation from the project specification. 15. What is the inspector's responsibility when it comes to sa fety on the project ?: Safety enforcement is not the responsibility of the inspector; however, it is his/her responsibility to report any issues that may affect the project.
