APOLOGIES  

1.  TECHNICAL PRESENTATIONS 

1.1  ‘Computer modelling of cathodic protection, applications on a harbour integrity design’, Ernesto Manuel Santana-Diaz, DNV and John Baynham, CM BEASY

2.  OPEN FORUM

2.1   The Chairman announced that one of the day’s speakers, Chris Fowler (Bodycote), had recently been chosen by NACE International as its Vice-President, and would also become the President the following year.  Congratulations were offered on this prestigious role.

2.2    The MCF had recently taken Membership of the World Corrosion Organisation, and was represented at the WCO General Assembly Meeting held at the NACE 2008 conference in New Orleans by Phil Dent (Bodycote; MCF Vice Chairman).  

• The meeting was chaired by George Hays (NACE) and attended by representatives from world-wide corrosion organisations including:  

• At the present time the organization has 4 founder members (NACE, ACE, CSCP and EFC) and 23 general members including MCF. It was reported that there is believed to be 73-74 corrosion societies world-wide and the aim of the WCO is to attract 50% to become members.  

• The Treasurer reported that 2008/2009 budget has been approved and the net surplus is $900-00.  
• Presentations were made by the four founder members on the strategic goals of the organization, which are:

#1 :    To Raise Public Awareness of Corrosion and Corrosion Control (Presented by Wayne Burns (ACA))

#2 :    To Identify World Best Practises in Corrosion Management (Presented by Kewei Gao (CSCP))

#3 :    To Facilitate the Provision of Corrosion Control Expertise to Governments, Industries and Communities (Presented by Paul McIntyre (EFC))

#4 :    To Normalise Corrosion Related Standards Worldwide (Presented by David Webster (NACE)) 

·        The one aim of the organisation is to gain status as a non-governmental organisation (NGO) of the United Nations.  The WCO has already gained charitable status which is the 1^st step in gaining UN NGO status.

 Further information on the WCO activities can be obtained from Phil Dent (phil.dent@bodycote.com) or by looking at the WCO website  (www.corrosion.org)  

2.3  Carol Powell (Copper Development Association) made an announcement to the meeting that there would be a European Federation of Corrosion Marine Workshop held the morning of the 11th September at Eurocorr 2008 in Edinburgh. It will be called Optimising the Performance of Copper base Alloys in Sea Water Piping Systems.  

It has long been recognised that copper alloys are sensitive to corrosion in stagnant and polluted waters and there is currently significant work underway particularly with copper nickels in naval applications to more fully explain and provide practical means of prevention. This has very beneficial implications to the marine industry in general.

The aim of the meeting is to look at the current status of copper alloy applications and identify specific areas where more understanding is required such that any future research needs can be identified and prioritised.

A programme of presentations will soon be available.  

2.4  Charlie Barraclough (Commtech Associates) had sent in a question: Had anyone knowledge of problems with hydrogen embrittlement (HE) of Thermally Sprayed Aluminium (TSA) Coatings on duplex stainless steels. 

Robin Oakley (QinetiQ) said that this should not be a problem provided the duplex is not subjected to stresses in excess of the proof stress (i.e. to plastic strains).  Chris Googan (Anti Corrosion Engineering) mentioned that a group sponsored project is currently being run on this topic and the results will be published in due course.  Ernesto Santana-Diaz (DNV) said that the DNV RP F112 relating to hydrogen induced stress cracking (HISC) may provide some guidance on the susceptibility of duplex stainless steels to HISC. 

2.5  Robin Oakley (QinetiQ) asked if anyone had knowledge of problems with polymers becoming chemically eroded adjacent to anode sites on cp systems and is this due to chlorine gas evolution at the anode? 

Barry Torrance (Aish Technologies Ltd) felt this would be due to chlorine gas evolution at the anode.  Chris Googan (Anti Corrosion Engineering) said that Cl / Fl resistant polymers will need to be selected. Polyethylene will degrade and also rubbers will be affected, since Cl attacks the C-C double bonds. 

At this point there was a break for lunch 

2.6  Barry Torrance (Aish Technologies Ltd) asked if anyone had a spent sacrificial anode that they could lend or give to him.

2.7  Barry Torrance (Aish Technologies Ltd) advised that Aish was presently carrying out some experimental work with impressed current anodes running at near-sacrificial voltages; any discussion on applications would be welcome.

3.  TECHNICAL PRESENTATIONS (part 2)
