WebIt can also be used to determine iso-corrosion diagrams and at which temperature the corrosion rate exceeds 0,1 mm/a. ISO 18069:2015 is not intended for excessive corrosion rates above 1 mm/a since an even higher corrosion rate indicates that the stainless steel is not suitable in the application. Web-below line {a} – water is unstable and must decompose to H2 -above line {a} – water is stable and any H2 present is oxidised to H+ or H 2O -above line {b} – water is unstable and must oxidize to give O2-below line {b} – water is stable and any dissolved O2 is reduced to H2O 3 regions: upper: - H2O electrolysed anodically to O2 lower: - H2O electrolysed …
WebThe Pourbaix diagram has a y-ordinate of potential or voltage and x-ordinate of pH. It is specific to one temperature and aqueous environment. The kinetic conditions are based upon Faraday's law combined with the Arrhenius rate equation. The combination of these two relationships results in a kinetic corrosion diagram, known as the Evans ... WebAug 1, 2024 · The diagram consists of lines, each representing an alloy and its corrosion rate at 0.1 mm a year. At temperatures or concentrations above the line, the corrosion rate tends to be elevated. If the concentration is below the line, the speed of corrosion is less.
