NACE CIP 1 Practice Exam Questions and Answers 100% Pass Anode - Answer-the electrode at which oxidation occurs. electrons flow away from the the anode in the external circuit. corrosion usually occurs and metal ions enter the solution at the anode cathode - Answer-the electrode at which reduction occurs. electrons flow towards the cathode in the external ciruit cathodic protection - Answer-A technique to reduce the corrosion of a metal surface by making that surface the cathode of an electrochemical cell. corrosion - Answer-the deterioration of a material, usually a metal, that results from a reaction with its environment. corrosion inhibitor - Answer-A chemical substance or combination of substances that, when present in the environment, prevents or reduces corrosion. crevice corrosion - Answer-localized corrosion of a metal surface at, or immediately adjacent to, an area that is shielded from the environment and full exposure due to the close proximity of the metal to another surface electrolyte - Answer-A chemical substance that promotes conduction of an electrical current galvanic series - Answer-List of metals and alloys arranged according to their corrosion potentials in a given environment (in sea water at 25 celcius) generalized corrosion - Answer-Corrosion that is distributed more or less uniformly over the surface of a material localized corrosion - Answer-Occurs at discrete sites and often in areas that are difficult to inspect mill scale - Answer-The oxide layer formed during hot fabrication or heat treatment of metals. Passivation - Answer-a layer of oxides formed on the surface of a metal that provides corrosion protection (ex stainless steel) a reduction of the anodic reaction rate of an electrode involved in corrosion, Pitting Corrosion - Answer-Localized corrosion of a metal surface that is confined to a small area and takes the form of cavities called pits. Return Path (Metallic Pathway) - Answer-Connects the anode and cathode, allowing passage of electrons, generated at the anode, to the cathode what are the elements of a corrosion cell - Answer-1. Anode 2. Cathode 3. Metallic pathway 4. Electrolyte what happens at anode - Answer-oxidation. metal dissolves into electrolyte what is the function of the electrolyte - Answer-Allows the passage of ions to connect the corrosion cell what is the function of the metallic pathway - Answer-Allows the flow of electrons to connect the corrosion cell The general rules of galvanic corrosion are: - Answer-The less noble (or more reactive) metal when connected to a more noble (or less reactive metal) will corrode preferentially name at least 5 factors that affect the rate of corrosion - Answer-temp, humidity, chemical salts, oxygen, pollutants General Corrosion - Answer-Uniform loss of material over an entire surface and general thinning of affected surface corrosion that is distributed more or less uniformly does not cause catastrophic failures Localized Corrosion - Answer-Occurs at discrete sites and often in areas that are difficult to inspect. concentrated and can cause catastrophic failures what are some of the common tools/methods used for corrosion control - Answer- inhibitors, design, cathodic protection, protective coatings, splash zone systems, altering the environment Coatings Specification - Answer-Formal, structured document containing information on a project (scope, terms, schedule, inspection, etc.) Instrument Calibration History Reports - Answer-Reports that normally contain information on how frequently each instrument is to be or has been calibrated. Materials Inventory Reports - Answer-Reports that contain information on the inventory of jobsite materials, and are normally submitted periodically safety data sheets (SDS sheets) - Answer-a form containing data of known substances in a particular product Quality insurance (QA) - Answer-any systematic process that checks whether a manufactured product or service being developed is meeting specified requirements quality control (QC) - Answer-Procedure intended to ensure that a manufactured product or performed service meets the requirements of the client or customer quality control technician - Answer-Inspector's role, primarily responsible for observing and reporting the technical aspects of a coating project and its conformance or deviation from the project specifications standards - Answer-a term applied to codes, specs, recommended practices, procedures, classifications, test methods, and guides that provide interchangability and compatability.
