In this time of relative isolation from friends and professional colleagues, CorroZoom seeks to build and maintain a worldwide community of scientists with mutual interests in the area of corrosion science. This webinar series will be free to everyone in the world. CorroZoom is not associated with any professional organization or society. An informal organizing committee has selected the speakers. Should it prove successful and the need continue, more speakers will be added.
Each webinar will only be synchronous, live only – you must be logged on to see it. The webinars will include a presentation of about 45 min in length and a discussion of about 15 min. Every participant will be able to submit questions for the speaker in the Zoom Q&A box, which will be handled by a moderator.
On 18 November 2021, the CorroZoom webinar will start at these times worldwide:
0800 | Columbus (US Eastern) |
1000 | Sao Paulo |
1300 | London |
1400 | Paris |
1600 | Istanbul |
1630 | Tehran |

Cerium conversion coatings on aluminium alloys
Ingrid Milošev
Jožef Stefan Institute, Ljubljana, Slovenia
Abstract
Conversion coating is formed on the metal surface by an electrochemical or chemical process. In the past, the most important coatings used for corrosion protection of aluminium alloys were chromate conversion coatings. Due to their negative impact on the environment and human health, alternatives have been sought in the last decades. Among those, coatings based on cerium (rare earth metal) are chosen to be the focus of this lecture. Both have been investigated for almost 40 years, bringing scientific data on coatings' formation mechanisms and properties regarding their composition, structure, thickness, and corrosion performance. In the first part of the lecture, some basic considerations of the chemistry of Ce salts and the general mechanism of coatings formation will be presented. This will be followed by the examples from our research work on this type of coatings, aiming to point out some specific issues which are still open to further investigation.
Biography
Dr Ingrid Milošev is the Head of the Department of Physical and Organic Chemistry at the Jožef Stefan Institute in Ljubljana, Slovenia, where she has worked since 1987. Dr. Milošev received a BSc in Chemical Technology in 1986 from the University of Zagreb and a PhD in Chemistry in 1993 from the University of Ljubljana. In the 1990s, she was a visiting researcher for two months at the University of Sherbrooke in Canada and then for almost two years at the Institute of Physical Chemistry of the Heinrich-Heine University in Duesseldorf, Germany. Her interest in corrosion protection methods includes corrosion inhibitors, sol-gel coatings, conversion coatings, and inorganic coatings. She serves on the editorial boards of several scientific journals.
CorroZoom Updates
Season 1 of CorroZoom has ended as of the last webinar on 9 June 2021. You can view the list of speakers from season 1 in the tab marked “Previous Webinars.” You will also find links to recordings of four of the six webinars.
The list of speakers of CorroZoom Season 2 will be announced here when it is available and by email to people for whom we have email addresses. If you are not on the CorroZoom email distribution list but want to be added, please send an email to guo.237@osu.edu.
Thanks to everyone for making season 1 of CorroZoom a huge success!
