Isocorrosion chart snapshot

  concept Isocorrosion chart Use Estimate corrosion rates for an alloy Select an alloy for a particular application with specific parameters Definition A plot of temperature versus electrolyte concentration, with lines depicting combination where similar corrosion rates are found example how to use it? An application needs a temperature and concentration as depicted by point 1 in the image above. We can plot it on the isocorrosion chart for that alloy and estimate the corrosion rate. The design of the component and corrosion allowance can be decided accordingly. A method to determine the suitability of the alloy for an application and electrolyte-temperature combination. Video below for practical demo of the use of the chart! Dive Deeper: Tips to begin experiments Do you like to solve quizzes ? https://corrospective.com 😀 Happy learning! 😀

CAREER OPTIONS IN CORROSION

  CAREER OPTIONS IN CORROSION The first time I studied corrosion was in 2009. The last 14 years have taught me one important thing - The path of a career in corrosion is not as straightforward as we are led to believe. Whether we are starting as a student of corrosion, or are entering the field after working as a non-corrosion person, there is always some career pathway that we are not aware of. There are research projects, certifications , audits, inspections , etc. EveryEng gave me the opportunity to share my learnings about the possible options in the field of corrosion . If you are someone who is starting or wants to switch to/between corrosion and its related fields, here is a short presentation for you! https://www.everyeng.com/mentor/course/view/3559864f 😀 Happy learning! 😀

Coupon test for corrosion inhibitors

Concept Coupon test is used to gauge a material's corrosion rate in a corrosive environment. It is also used to test the efficiency of corrosion inhibitors. Parameters Material - The coupons are made from the same or similar material as that of the actual component Electrolyte - The electrolyte for exposure is the same or similar to the actual environment. Sometimes, coupons are placed in the actual environment with the component, for example in the soil with submerged pipelines. Steps Clean the coupon of any oil/grease/rust Measure the weight of original coupon - W Measure the Area of coupon to be exposed - A. Take photographs and/or optical micrographs of the coupon Immerse the coupon in the electrolyte without inhibitor Note the time of measurement - t. This is decided by the concerned parties or as per the standards followed. Take out the coupon after the time. Take photographs and/or optical micrographs of the coupon Clean the corrosion products off the coupon. DO NOT USE ROUG...
