1. 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 Path- way, Electrolyte 5. Describe what happens at the 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 cell 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 reac- tive) metal when connected to a more noble (or less reactive metal) 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 surface, 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 loss 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 safety 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. 16. Name some tests that may need to be conducted during surface prepara- tion and coating operations.: Temperature, Relative Humidity, Dew Point, Anchor Profile, Surface Cleanliness 17. Name some of the documentation/reports that may be required to be maintained on a coatings project.: Daily/weekly summary, material usage re- ports, manpower and equipment, non conformance, and conformance 18. What are the most important characteristics of a good report?: Objective, Accurate, and Detailed. 19. What is the inspector's primary responsibility and what should the in- spector not do as it pertains to the specification.: The Inspector's primary responsibility as the inspector is to "enforce" specification. The inspector is NOT to make changes to the specification for any reason. 20. What type of information could you expect to find on a Product Data Sheet?: Surface preparation and application information such as recommended level of surface cleanliness, recommended appli
