NACE CIP Level 1 Study Guide Latest Updated 2022 Define Corrosion Correct Answer- The deterioration of a substance, usually a metal from a reaction with its environment What is passivation? Corr ... ect Answer- A layer of oxides formed on the surface of a metal that provides corrosion protection. What is an example of passivation? Correct Answer- Stainless Steel What are the elements of a corrosion cell? Correct Answer- Anode, Cathode, Metallic Pathway, Electrolyte Describe what happens at the anode. Correct Answer- The metal dissolves into the electrolyte What is the function of the electrolyte? Correct Answer- Allows the passage of ions to connect the corrosion cell What is the function of the metallic pathway? Correct Answer- Allows the flow of electrons to connect the corrosion cell What is the galvanic series? Correct Answer- A listing of metals in order of reactivity (more or less noble) in seawater at 25 C The general rules of galvanic corrosion are: Correct Answer- The less noble (or more reactive) metal when connected to a more noble (or less reactive metal) will corrode preferentially Name the five most important factors that affect the rate of corrosion. Correct Answer- Humidity, oxygen, chemical salts, pollutants, temperature General corrosion is: Correct Answer- 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 Localized corrosion is: Correct Answer- 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. List some of the common tools/methods used for corrosion control. Correct Answer- Design, Inhibitors, Material Selection, Cathodic Protection, Protective Coatings, Splash Zone Systems, Alteration of the Environment How does NACE define the inspector's role? Correct Answer- The inspector's role is that of a quality control technician responsible for observing and reporting conformance or deviation from the project specification. What is the inspector's responsibility when it comes to safety on the project? Correct Answer- Safety enforcement is not the responsibility of the inspector; however, it is his/her responsibility to report any issues that may affect the project. Name some tests that may need to be conducted during surface preparation and coating operations. Correct Answer- Temperature, Relative Humidity, Dew Point, Anchor Profile, Surface Cleanliness Name some of the documentation/reports that may be required to be maintained on a coatings project. Correct Answer- Daily/weekly summary, material usage reports, manpower and equipment, non conformance, and conformance What are the most important characteristics of a good report? Correct Answer- Objective, Accurate, and Detailed. What is the inspector's primary responsibility and what should the inspector not do as it pertains to the specification. Correct Answer- 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. What type of information could you expect to find on a Product Data Sheet? Correct Answer- Surface preparation and application information such as recommended level of surface cleanliness, recommended application methods and equipment such as tip sizes. Also, environmental parameters for application such as max and min temperatures, curing times, recoat windows. What type of information could you expect to find on a Safety Data Sheet? Correct Answer- Health, safety and environmental. The PPE required. Physical characteristics. Emergency responder information. Explain the difference between Quality Assurance (QA) and Quality Control (QC). Correct Answer- Quality Assurance - Any systematic process of checking to see whether a product or service being developed is meeting specs. Quality Control - A procedure or set of procedures intended to ensure that a manufactured product or performed service adheres to a defined set of quality criteria or meets the requirements of the client or customer Identify some of the defects that can be caused by incorrect application temperatures. Correct Answer- Failure to cure, too rapid solvent evaporation, poor film formation Describe relative humidity. Correct Answer [Show More]
