Kentaro Hata (JFE Steel Corporation)23/06/2021, 10:40Hydrogen EmbrittlementOral PresentationZinc coated high strength steel sheets are applied to the automotive part due to the superior corrosion resistance and the lightweight of car body. The hydrogen absorption into the high strength steel sheet has been known to be promoted by zinc coating during corrosion, however, its behavior has not been clarified. In this study, the effect of corrosion status of zinc coating on the hydrogen...Go to contribution page

Dominique Thierry (French Corrosion Institute)23/06/2021, 11:00Fundamentals on Atmospheric Corrosion and Corrosion ModellingOral PresentationA compact and autonomous corrosion sensor using the principle of electrical resistance variations of its metallic sensitive tracks has been used for different applications under atmospheric corrosion conditions. The measurements of the corrosion rate can be performed in-situ both under laboratory and field exposures. From the results, it is possible to better understand the atmospheric...Go to contribution page

Masataka Omoda (JFE Steel Corporation)23/06/2021, 11:20Fundamentals on Atmospheric Corrosion and Corrosion ModellingOral PresentationFor prediction of corrosivity of steel products used in atmospheric environments, exposure tests in the actual environment have been widely conducted. Long-term corrosion loss has been predicted by extrapolating the change of corrosion loss with time in exposure tests. However, the data of exposure test in regions where we would like to know corrosion rate doesn’t always exist. In this case,...Go to contribution page

Shunsuke Yamamoto (JFE Steel Corporation)23/06/2021, 11:40Automotive Corrosion BehaviorOral PresentationZinc coated steel sheets are used in order to protect corrosion of automobile bodies. It is well known that the type of automotive corrosion can be divided into perforation corrosion and cosmetic corrosion. Although the mechanism of the perforation corrosion has been studied well, the mechanism of the cosmetic corrosion has not been clarified yet. In this study, an in-situ observation...Go to contribution page

Rinta Sato (JFE Steel Corporation)23/06/2021, 12:00Fundamentals on Atmospheric Corrosion and Corrosion ModellingOral PresentationGlobal expansion of automotive market leads to demand for optimization of materials selection corresponding to the corrosion severity in environments. Although great efforts have been devoted to study the corrosion behaviour of steel products in East and Southeast Asia, reports concerning corrosion occurring in the automotive body in those regions are still quite limited to the date....Go to contribution page
