 1.   MCF NEWS 

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. 

The 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 October. 

Ideas 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. 

A 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. 

To 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.      TECHNICAL PRESENTATIONS (part 1):

 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

3.      OPEN FORUM.  

3.1   Ian Hamilton (Aker Kvaerner) asked what was known of Ferrous Particle contamination of Austenitic Stainless and Austenitic/Ferritic Duplex Steels.    

David 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.   

It 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.

3.2     Barry 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. 

3.3   Report on final year of MCF-led collaborative project on Erosion-Corrosion, Hang ‘Jackie’ Meng, PhD student (Leeds University), supervisors: Prof. Anne Neville & Dr. Xinming Hu

This presentation contained an overview of the work done, and the main conclusions.

 

4.    TECHNICAL PRESENTATIONS  (part 2):

 4.1  Testing and Experience of Metallic Components in Subsea Hydraulic Control Fluids', Simon McManus, MacDermid Offshore Solutions

4.2 ‘Learning From Failures 2’, Derek Bates, Materials Technology Ltd

The Chairman closed the meeting at approx. 3:30 pm
