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!
