The meeting was opened by the Chairman, Clive Tuck
1.1 The Secretariat presented the list and topics of forthcoming meetings. 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. Only one member company had not yet paid their 2005 subscription, and financial statements were available for those who wanted one. CD-Business cards advertising the MCF were available, and members were encouraged to take some of these to pass on to potential members.
1.2 MCF/NACE Conference: Offshore Materials & Corrosion: 40 Years On. The Chairman announced that plans were going ahead for this conference, which was also endorsed by ICorr Aberdeen. The Radisson SAS Hotel Edinburgh had been booked for 20th 22nd June 2006, and a programme of 16 invited speakers would cover a variety of relevant topics. Brochures would be available very shortly.
Standards, Quality & Design Issues in Materials for Seawater Systems,
Roger Francis (Weir Materials & Foundries)
2.2 Keynote Lecture: 2.1 Performance Monitoring and Analysis of Ships Tank Coatings, Keith Lucas, Director of Center for Corrosion Science & Engineering, US Naval Research Laboratory
Robin Oakley (QinetiQ) mentioned a problem with a CuNi seawater system
heat exchanger. Coating with
electroless Ni with PTFE particles to stop biofouling has been tried.
This was an alternative to chemical cleaning which wasnt possible.
Galvanic compatibility of these materials? It was felt that this type of coating would be very porous,
giving micro-cracks. Electroless
nickel preparations often involve phosphoric acid or phosphates.
Phosphorus and CuNi dont go well together.
It was felt that the natural biofouling resistance of CuNi should be
utilised, if possible.
EUROCORR 2006 - EFC WP9 MARINE CORROSION.
Roger Francis (Weir) brought the EuroCorr
Conference to the attention of members. Their
marine corrosion working party is organising a one day symposium at the above
conference (Sept 25th 28th, Maastricht, Holland).
The subject will be laboratory corrosion testing and its relevance to
service performance. Bob Kain (LaQue
Labs) has been invited to give the Plenary Lecture.
Bob has been active in the field of marine corrosion testing for 40 years
with many publications on a wide range of materials and coatings.
The working party welcomes offers of papers
and for more information contact the WP9 chair, Ulf Kivisakk ([email protected]).
Schleich (KME) mentioned that there would be a common session with the Cathodic
Protection working party, on sub-sea pipelines. More details could be found on www.eurocorr06.nl.
Papers from, and attendance of, MCF members would be very welcome.
3.3 Wilhelm Schleich (KME) explained to members
that KME and CDA thought that it could be valuable to have an MCF sub-group to
discuss research and use of copper alloys in seawater.
If this were set up experiences could be shared, and possible standards
could also be discussed. Details will be circulated to members, and anyone
interested in taking part should contact the Secretariat, who will compile a
3.4 Barry Torrance (Aish) had a question on the
performance of impressed current electrodes.
He showed a few slides of a steel plate containing a cathode and several
anodes immediately after removal from seawater, and also after one night.
There was an interesting pattern around the cathode, which darkened after
exposure, but he wondered what it was. Magnetite,
partial oxide or sulphide? It was
suggested that he scrape off some of the black substance and test it with a
magnet, since the patterns were typical of those of a magnetic field.
It was most probably magnetite which forms from the initial FeOOH
deposit. The magnetite would be
expected to convert easily to reddish Fe2O3, which was
observed on the plate when left moist overnight.
TECHNICAL PRESENTATIONS (part 2):
4.1 Report on first year of MCF-led collaborative project on Erosion-Corrosion, Hang Jackie Meng, PhD student (Leeds University), supervisors: Prof. Anne Neville & Dr. Xinming Hu
in Water Distribution & Closed Recirculating Systems,
Phil Munn (Corrosion & Environmental Services Ltd)
The Chairman closed the meeting at approx. 3:30 pm
