These were accepted as a true record of that meeting.
David Peacock (TIG) mentioned that Roger Francis' new book had received an excellent review in the journal Materials World. ["Galvanic Corrosion; A Practical Guide for Engineers" Roger Francis, published by NACE, available from the NACE Website (www.nace.org)].
The membership total stands at 34 in 2001. 4 members have not yet sent their subscription cheques, but most are in the process of doing so.
Only 1 subscription cheque was collected in period 1st July to 1st Oct. 2001 giving an income of £587.50. The total expenditure was £6,782.32, which included DERA secretariat expenses, facility hire for 2 meetings, and Virtual Internet Fees. This left the fund balance at 1st October 2001 at £23,824.92.
Clive Tuck (Meighs) reported to the membership that the committee was looking at plans to improve the Club facilities for members with the aim of retaining and increasing membership, since members often found it difficult to justify the cost of membership and attendance at meetings. Press releases for Stainless Steel World, Materials World and the ICorr Magazine were being considered.
Jean Tuck (Secretariat) reported on the new features of the web-site. There is already a 'Stop Press' section, for which news items (e.g. forthcoming meetings of relevance) from members would be welcomed. Also planned were pages for each member, and also links to, and from, other relevant web-sites on a quid pro quo basis. It was suggested that such links could be 'hot-links' to members, and 'cold-links' otherwise. Data from members for their own pages was requested, as was a list of sites that members would like to see linked with that of the Club
The list of forthcoming presentations was displayed, and further volunteers or ideas were requested.
Paul Woollin (TWI) asked about the aims and scope of the Club, and was referred to a statement of the Scope of the MCC (as printed on the Club's advertisement/flyer)
Keith Stokes (DSTL) said any ideas on the Club's future were welcome. David Howarth (Lloyds Register) suggested that venues might be offered by members, which could help to reduce costs. He offered Lloyd's Register facilities in the City of London.
Clive Tuck (Langley Alloys Divn., Meighs Ltd) asked: 'What can be used as a good insulator between a galvanic couple such as a copper alloy bolt in a carbon steel flange?'
Sleeves and washers made of TUFNOL have been found to be effective as it has sufficient bearing strength to withstand loading (care should be taken to see that the TUFNOL fibres are aligned in the correct direction for loading). TUFNOL used in this way has been found to last up to 30 years.
Alumina sprayed coatings can be used as an insulating layer but its effectiveness is dependent on how well it is applied (adhesion is problematic).
Coating of the cathode to reduce corrosion current will act to mitigate corrosion. IRATHANE coatings have been used on titanium and stainless steel. Belzona products have also been used for this purpose.
For threaded joints, Loctite products can be applied to the thread which will act as an electrical insulation layer in service.
David Howarth (Lloyds Register) asked if the Club had a list of consultants. It was generally felt that an updated list of members, with subject area and contact list, would be useful. This could link with improvements already planned for the web-site, but a hard copy circulated to members would also be appreciated.
The next meetings will be held on the following dates:
23 January 2002, IOM, London
9 April 2002, Stakis Hotel, Aberdeen
3 July 2002, National Motorcycle Museum, Birmingham
9 October 2002, IOM, London
22 January 2003, IOM, London
8.1 'Why or is there a gap between laboratory test data and field experience using high alloyed SS for seawater handling', Trond Rogne (SINTEF).
8.2 'Hydrogen Embrittlement Stress Corrosion Cracking of Superduplex Stainless Steel Under Cathodic Protection', Paul Woollin (TWI).
8.3 '25% Cr Superduplex Stainless Steel - 35 years old and still going strong(er)', Clive Tuck (Langley Alloys, Meighs Ltd)
8.4 "Post Fabrication Cleaning: Some Why's and Wherefore's", Chris Baxter (Avesta Polarit).
