2. Minutes of the previous meeting (18 January 2000)
- In the minutes of the previous meeting, David Peacock (Titanium Information Group) was wrongly reported as saying that galvanic corrosion occurred when graphite was in contact with titanium. David Peacock pointed out that this was the opposite of the case. He reported that metals and materials such as graphite and carbon fibre composites, which are even more corrosion resistant than titanium, raised the corrosion potential of titanium into the passive region. Hence, these materials may be coupled to titanium and maintain its resistance in reducing as well as oxidising environments.
In the minutes of 5 July 2000, David Peacock was also reported as saying that there was little field experience to provide more information on the subject. David Peacock confirmed this and added that little was known on the behaviour of titanium in crevices and the effect of a raised potential in this environment.
- Apart from the particular section mentioned above, the minutes were accepted as a true record of that meeting.
3. Matters arising from the minutesThere were no matters arising.
4. Membership/financial status
- Babcock Engineering Services Limited, MacTaggart Scott & Co. Ltd, and STSN Centre Matériaux resigned from MCC. The membership total is now 37. It is planned that Stainless Steel Fasteners Ltd will join MCC in 2001, which will raise the membership to 38.
- The financial details are attached in appendix. The total expenditure for 1/7/00 to 10/10/2000 was £4,331.36, with £12,000 being transferred to the reserve account. The balance in the current account at 10/10/00 was £13,991.09. The following are still outstanding: (i) staff costs for DERA (£5070), (ii) secretariat expenses (£1040), and (iii) new Logo costs (£180). The effective fund total at 10/10/00 was £19,701.09.
5. Open forum
- Roger Francis (Weir Material Services) informed those present that John Oldfield and himself were the UK representative of the European Federation of Corrosion (EFC). The EFC is an association of committees working on corrosion throughout Europe. These working parties meet about three times a year and are open to anyone with an interest in corrosion. An example of the activities of EFC is the organisation of a major international conference on corrosion, Eurocorr. Roger Francis announced that EFC was keen to collaborate with MCC through their activities over the next three years. Possible areas include:
- Publications, that any working group can generate. For example, a thorough report has recently been published on crevice corrosion, including over 1000 references. To obtain a copy of the report or for any information on publications, contact Paul McIntyre from IoM.
- Developing reliable laboratory test methods to measure corrosion on stainless steels. Various laboratories from Europe will collaborate and the results of the study will be presented at seminars. One session of Eurocorr 2000 was dedicated to the subject. The conference proceedings can be obtained through Paul McIntyre.
- Developing a website, possibly in collaboration with MCC. Links will be established between the MCC and EFC websites.
The next active working group meeting will be held in April or May 2001 in Copenhagen. The group is about to start work on a survey of the performance of aluminium alloys and copper alloys in marine service and is open to any member of the MCC willing to get involved. Again, for more information on the meeting, contact Roger Francis (Weir Material services) or Paul McIntyre (IoM).
Alan Turnbull (NPL) reminded those present that the DTI was preparing a research programme entitled 'Life performance of Materials'. Details were given at the previous MCC meeting (see Minutes of the meeting held on the 5th of July 2000). A questionnaire is attached to the minutes for the companies wishing to participate in the programme definition.
- Stuart Bond (TWI) informed those present that TWI was developing a program of work on the optimisation of materials selection for seawater handling systems in the Middle East. For more information, a booklet is attached to the minutes.
6. Any other business
- Keith Stokes (DERA) announced that Brian Bell (Mentor Engineering), a speaker for this general meeting, had sent his apologies. Unfortunately, due to the short notice he had received and other commitments on the days before the meeting, the back-up speaker, Keith Stokes, was not able to bring his presentation slides. In the time slot initially allocated to the presentation, Keith Stokes (MCC Chairman) invited members of the audience to give an introductory talk to inform members of their activities; Barry Torrance (Widney Aish), Manfred Jasner (KME), Clive Tuck (Meighs), John Fowler (Rolls Royce plc), Peter Webster (Copper Development Association) and David Jones (UMC International) gave an introduction of their company activities.
- It was announced that Brian Bell would be contacted to reschedule his presentation.
- Keith Stokes (MCC Chairman) suggested that the MCC may wish to participate in a series of corrosion workshops, in collaboration with NiDi (Contact: Peter Cutler) and TIG (Contact: David Peacock). These would be held in 2001 at venues to be discussed. For example, MCC members who wish to get involved could act as hosts for the seminars/fora of particular interest to them.
David Peacock (Titanium Information Group) suggested that the workshops could be organised as talkshops rather than formal seminars. The sessions could start with a short presentation from an expert in the field, followed by a frank discussion between members of the audience, openly discussing various problems and their solutions.
Keith Stokes (DERA) invited members of the club to put forward their thoughts on topics to be discussed at these workshops. The following topics were suggested:
- Subsea bolting
- Materials selection
- Joining of dissimilar materials; the engineering aspects and corrosion effects
- Corrosion modelling
- ICCP systems in marine applications
