The meeting was opened by the Chairman, Clive Tuck
1.1 The Chairman began by welcoming everyone to the meeting.
He then described the current position with respect to the MCF-led
Erosion-corrosion project at Leeds University.
project has now ended and Jackie, the PhD student, will be presenting a summary
of his work at this meeting. Discussions
are now going on to see if a follow-on project can be arranged at Leeds.
If anyone is interested in participating then please let the Secretariat
know. The project would start next
for new possible jointly-funded projects would also be welcomed, and the MCF
would assist the process of getting the project set up.
1.2 The Secretariat outlined the basic financial position of the MCF (see
details in appendix), and asked if anyone wished to contribute a presentation to
the Programme for 2008/9, as this was filling up.
matter for the attention of members was the forthcoming AGM, which would be an
opportunity to nominate further committee members (there are currently two
spaces on the committee), and to decide what should be done about choosing the
next Chairman. The position of
Chairman was originally for 3 years maximum, but the Constitution was altered,
by vote, in 2005, to permit a term of up to 6 years, since there was a shortage
of possible candidates. The 6 years
was now up. Ideally a new
candidate(s) would be nominated, otherwise it would be necessary for the members
to decide whether the Constitution should be amended again, to allow the current
Chairman to continue.
facilitate thought on the matter the Nomination Forms would to be sent out with
the October Minutes, rather than with the January Calling Notices.
She reminded the membership that CPD certificates were always available after meetings for those who wished to use these to build up their CPD portfolio.
2.1 ‘Natural Products for Anti-fouling Coatings’, Lily Chambers, Southampton University & Keith Stokes, DSTL
2.2 Keynote Lecture: The Replacement of Corrosion-resistant Castings by Fabricated Weld Overlay Components’, Norman Cooper, BAE Systems
Ian Hamilton (Aker Kvaerner)
asked what was known of Ferrous Particle contamination of Austenitic Stainless
and Austenitic/Ferritic Duplex Steels.
Howarth (Lloyd’s Register) said that this is often seen on propellers and
after tank cleaning – it is a common phenomenon.
Derek Bates (Materials Technology) added that it is not uncommon in the
pharmaceutical industry where the surface staining was not acceptable, even
though it was not found to be aggressive to the steel.
DH said that it can, however, become aggressive if it gets embedded
during grinding, with a contaminated grinding wheel.
DB mentioned that it was also a common problem in the yachting industry
where the lack of shine on components is disliked.
Norman Cooper (BAE Systems) said that one can get a ‘lion paw prints’
pattern over components, caused by marks from handlers’ fingers.
This is usually removed by alumina blasting and pickling.
Charlie Barraclough (Commtech) said that if one leaves contamination in
saline environment it will continue to corrode, such as when lying on dockside
awaiting fitting. The
effect is worse in hot marine climates.
was felt that the seriousness depends on application – pharmaceuticals use
pickling to remove the staining and it is recommended to pickle stainless steel
after grinding. Interestingly,
in seawater which is oxygen-free the effect of this type of contamination is not
as marked. Overall, the
evidence was that this type of contamination acted to weaken the passivity of
the stainless steel.
Torrance asked whether anyone wished to invite Pierre Roberge (of the Royal
Military College, Kingston, Canada) to visit their company.
He had been invited to give a presentation to the MCF, but would need
further reason to travel.
Report on final year of MCF-led collaborative project on
Erosion-Corrosion, Hang ‘Jackie’ Meng, PhD student (Leeds University),
