NACE CIP 1 EXAM Practice Questions with Correct Answers Latest 2023 | 2024 (Graded) NACE CIP 1 EXAM 2023/2024 Anode - answerthe 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 - answerthe electrode at which reduction occurs. electrons flow towards the cathode in the external ciruit cathodic protection - answerA technique to reduce the corrosion of a metal surface by making that surface the cathode of an electrochemical cell. corrosion - answerthe deterioration of a material, usually a metal, that results from a reaction with its environment. corrosion inhibitor - answerA chemical substance or combination of substances that, when present in the environment, prevents or reduces corrosion. crevice corrosion - answerlocalized 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 - answerA chemical substance that promotes conduction of an electrical current galvanic series - answerList of metals and alloys arranged according to their corrosion potentials in a given environment (in sea water at 25 celcius) generalized corrosion - answerCorrosion that is distributed more or less uniformly over the surface of a material localized corrosion - answerOccurs at discrete sites and often in areas that are difficult to inspect mill scale - answerThe oxide layer formed during hot fabrication or heat treatment of metals. Passivation - answera 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 - answerLocalized corrosion of a metal surface that is confined to a small area and takes the form of cavities called pits. Return Path (Metallic Pathway) - answerConnects the anode and cathode, allowing passage of electrons, generated at the anode, to the cathode what are the elements of a corrosion cell - answer1. Anode 2. Cathode 3. Metallic pathway 4. Electrolyte what happens at anode - answeroxidation. metal dissolves into electrolyte what is the function of the electrolyte - answerAllows the passage of ions to connect the corrosion cell what is the function of the metallic pathway - answerAllows the flow of electrons to connect the corrosion cell The general rules of galvanic corrosion are: - answerThe 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 - answertemp, humidity, chemical salts, oxygen, pollutants General Corrosion - answerUniform 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 - answerOccurs 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 - answerinhibitors, design, cathodic protection, protective coatings, splash zone systems, altering the environment Coatings Specification - answerFormal, structured document containing information on a project (scope, terms, schedule, inspection, etc.) Instrument Calibration History Reports - answerReports that normally contain information on how frequently each instrument is to be or has been calibrated. Materials Inventory Reports - answerReports that contain information on the inventory of jobsite materials, and are normally submitted periodically safety data sheets (SDS sheets) - answera form containing data of known substances in a particular product Quality insurance (QA) - answerany systematic process that checks whether a manufactured product or service being developed is meeting specified requirements quality control (QC) - answerProcedure intended to ensure that a manufactured product or performed service meets the requirements of the client or customer quality control technician - answerInspector'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 - answera term applied to codes, specs, recommended practices, procedures, classifications, test methods, and guides that provide interchangability and compatability.
