Investigation of the importance of heat transfer during thin electrolyte formation in atmospheric corrosion using a novel experimental approach

Tijdschriftbijdrage - Tijdschriftartikel

During atmospheric corrosion of metals, the evolution of thin-film electrolyte thickness is the primary factor that determines corrosion rate. Understanding the evolution of the electrolyte thickness as a function of the key environmental parameters is yet to be achieved. Therefore, in the present article, a novel methodology has been developed to conduct experiments under regulated environment to measure the evolution of the film thickness on an undisturbed metal surface using an interferometer. Experimental results are compared with the previously developed simulation model. The heat transfer coefficient is noted as a critical parameter influencing the film characteristics and resulting corrosion rate.
