Chairman, Robin Oakley, opened the meeting at 11:10 am.
1.1 ‘Optical 3D Surface Metrology’, Brian Kyte, Alicona
and Anti Fouling’, Steve
·2.1 Clive Tuck (Lloyd’s Register) asked a question regarding corrosion of 90/10 CuNi heat exchanger tubing. There was a recent case of tube perforation on a heat exchanger where the failures were caused by internal pitting in the tubes at a distance of 40-60mm from the tube ends. The tube sheet was also of 90/10 CuNi and about 30mm thick. The pit morphology was interesting in that the pits were elongated perpendicular to the direction of flow (ie parallel to the front face of the tubesheet.
Roger Francis (RA Materials) asked if the system was cathodically protected and CT said that it was. There was a large zinc anode situated centrally with respect to the tubesheet at a distance of about 50 mm from it. RF said that, in the situation described, the failure was most likely down to cathodic overprotection. He had been involved with work at BNFL with a similar case. They had proposed a mechanism which involved deposition of calcium carbonate and copper sulphide at a distance down the tubes which represented the extent of the anode throwing power (about 5x diameter). Under-deposit corrosion was likely in these areas, producing pits which grew in a parallel direction to the front of the tubesheet, as seen in the current example. In order to overcome occurrence of the phenomenon as seen at BNFL, anodes with a lower electrode potential were employed such as mild steel.
2.2 Barry Torrance (Aish Technologies) asked if any attendees knew of the existence of large scale seawater flow test facilities, (8” diameter and above).
2.3 Robin Oakley (QinetiQ) asked for alternative material choices to brass for the bush on an underwater electrical control knob operating against a 316 stainless steel spindle?
In discussion it was suggested (by Roger Francis, RA Materials) that either matching 316 stainless, if loads are low and galling not a problem, or machined 5% tin phosphor bronze, which would be more resistant to pitting and dealloying than the brass.
TECHNICAL PRESENTATIONS continued
includes a short presentation, and an Open Forum item, held over from the
3.1 ‘Response of 70-30 CuNi to conditioning pre-treatments and sulphide exposure’, R Oakley & J. Galsworthy, QinetiQ
3.2 ‘Mathematical Modelling of Interactions Between Impressed Current and Sacrificial Anode Cathodic Protection Systems in Offshore Installations’, Robin Jacob, Corrosion Consultancy & Cristina Peratta & John Baynham, CM BEASY
on the World Corrosion Organisation. Phil
Dent, Bodicote, made a presentation on the World Corrosion Organisation (WCO).
The organisation was founded by NACE (North America), EFC (Europe), ASA (Australia) and CSCP (China) in 2007 and now has 27 member world-wide societies. The MCF has been a member society since 2008 and is one of three in the UK (IOM3 and ICorr).
The WCO has a mission statement “To
promote education and best practices in corrosion control for the benefit of
society, preservation of resources and protection of the environment” and
has four goals in its strategic plan: -
To raise public awareness of corrosion and corrosion control
To identify world best practices in corrosion management
To facilitate the provision of corrosion control expertise
to governments, industries and communities
To normalize corrosion related standards worldwide
is preparing a ‘white paper’ on industry needs – cost of corrosion, with
the aim to present the WCO study to
the UN, National Governments & other interested groups. Workshops
have already been organised in Edinburgh (Eurocorr), Salt Lake City (NACE),
Beijing (CSCP), Las Vegas (ICC) and Wellington (ACA). A
final workshop in Frankfurt has been planned for the spring of 2009.
The WCO has a
target “to have a membership consisting
of a majority of the world’s not-for-profit corrosion related organizations by
May 2009”. The WCO plans to
apply for NGO status with the United Nations in the spring of 2009, in order to
participate in the UN’s public affairs and environmental functions.
will be holding its next meetings at the NACE 2009 conference in Atlanta and
Phil Dent will be representing the MCF at the General Assembly Meeting on 24th
March. Further details on the WCO
can be obtained from www.corrosion.org
The main meeting closed at approximately 3.00pm,
and was immediately followed by the Annual General Meeting.

MINUTES OF LAST ANNUAL GENERAL MEETING (23 January 2008)
only nomination for the Management Committee was Julian Wharton of the
University of Southampton. He
had been co-opted by the committee as an academic representative when his
colleague, Robert Wood, had resigned due to pressure of work.
Howarth (Lloyd’s Register) had stepped down from the committee.
Clive Tuck (Lloyd’s Register) was already on the committee as
Immediate Past Chairman. This
was now a one-year position, but he could revert to an ordinary committee
member if the Forum was in agreement.
These two candidates were nominated by the committee and accepted by the meeting. The Chairman pointed out that there was still further space on the committee and volunteers/nominations would be very welcome for next year!
What can I remember of my first year as Chairman of the MCF? I was impressed with how well it was set up and handed over to me by Clive Tuck. It would otherwise have been a great deal of work to get established. There have been a number of well-attended meetings; attendance seems not only to be holding up, but actually increasing, providing a very good opportunity for networking.
Our Aberdeen meeting was extended by one additional speaker and this provided a good link with the ICorr branch meeting which followed on. We plan to do the same again this year.
Membership fluctuates each year, but it has stayed at the same healthy level for 2008. My only regret is not having more time to devote to spending on the MCF.
At the end of 2008 the
membership stood at 30, the same as in 2007.
We lost 4 members: BP, Clyde Pumps, DNV and Vetco Gray. 4 companies joined us:
CM BEASY, British Energy, Corrosion Control and Impalloy.
A list of members will be sent out, as usual, with the January
The end of year accounts were detailed for members. Copies are sent to members with the printed or pdf minutes.
For 2009 the Management Committee have decided to leave the rates at the 2008 level.
The Full membership fees are therefore £655, but with a £100 discount for those companies that pay by 1st May 2009.
Overseas membership and Sole
Trader membership will be £410 with a similar £100 reduction for
prompt payment. Overseas
payments not in sterling will incur a charge of £50 to cover our bank
costs. A facility for
payment by credit card is also be possible, but there is a small charge for
this to cover the costs to MCF of making the credit card transaction.
booklet of member company Laboratory Facilities, produced last year, has
been updated. It is available
in pdf format and can be found on the MCF website.
A similar document has been produced for member Consultancies.
These can easily be updated, so any member company wishing to
participate in these, or requiring their details changed, should make a
request to the Secretariat.
CPD certificates continue to be available at meetings, and we have been pleased to have the continued recognition of IoM3 and IMarEST for these.
The MCF web-site continues to provide a popular contact point. The average number of visits to the web-site, for the last quarter of 2008, was 360 per day, 40% up on the same period last year. Links on the site enable interested parties to request further information about the MCF, or to request an invitation to a meeting.
The search facility continues to be used regularly. Recent popular search terms have been: “corrosion, experiment, bolts, marine, paint, testing, propeller, seawater & detection”. All available abstracts of presentations going back to the early days of the MCF are still available for reference on the site. The News page gives details of conferences and other items likely to be of interest to members. As usual, further items are always welcomed.
The Chairman thanked the Secretariat for her efforts.
Acceptance of these accounts was proposed by Roger Francis (RA
Materials) and seconded by Robin Jacob (Corrosion Consultancy), and accepted
by the meeting as correct.
Possible MCF-led Project(s): The Management Committee
were looking in to the possibility of having future MCF-led project(s)
similar to that done over the last few years with the University of Leeds.
Several member companies had taken part, and the MCF itself had
benefited from several project updates being presented at the meetings.
Details would be passed round to members as these emerge.
Members could then comment on the suitability and any interest within
their own companies.
Possible Future MCF or MCF/partner Conference: The MCF has traditionally run a conference, at around 4-yearly intervals. If a 2010 or 2011 conference was to be considered, then planning should commence shortly. The committee would welcome any ideas from members on whether or not this would be good, and if so, what type of subject area should be covered, and whether we should look to have a partner in the way that NACE UK were involved with the last conference.
