Corrosion of metals is a complex subject. Planned regular maintenance or replacement regimes can be a solution to alloys with known service lives and be more economic where the system is accessible and labour is cheap. High reliability materials are the alternative solution and often provide lower life cycle costs than cheaper first cost, less reliable systems.


This article has attempted to highlight some of the considerations but for further knowledge about the subject the following information is suggested:


1. The corrosion performance of metals for the marine environment: a basic guide, EFC/NACE Publication 63. Edited by Carol Powell and Roger Francis, Maney Publishing. 2012


2. Copper Alloys for Marine Environments, CDA Publication 206. 2012


3. Copper Alloys in Seawater. Avoidance of Corrosion. R. Francis, CDA Publication 225. 2016


4. Guide to Nickel Aluminium Bronze for Engineers, CDA Publication 222. 2016


5. Galvanic Corrosion. A Practical Guide for Engineers. R. Francis, NACE International. 2017


Copper Development Association and Nickel Institute also provide in-house workshops on corrosion of metals in seawater. Contact info@ copperalliance.org.uk for further information.


Obituary Mark Tur CEng MIMMM MCIM MBA 1958 –2018


Since the completion of this article one of the authors, Mark Tur, has sadly passed away. Mark joined Copper Development Association in 2007 as a Technical Consultant, with 20 years’ experience in the non-ferrous metals industries. His first role was as a metallurgist at Stone Manganese Marine, a heavy foundry specialising in marine propellers, and he completed his time in industry as Managing Director of metal tube producer, Cole and Swallow Materials.


During his 11 years with CDA, he was a fervent supporter of education and professional development initiatives, eager to share his extensive experience with the next generation. Mark developed and delivered many training presentations, workshops and lectures on copper alloys for marine and antimicrobial applications. He connected well with his audiences as he understood both their technical and commercial requirements. Mark was generous with his time and knowledge, had a great sense of humour and was always ready to help. He was a highly respected expert both within the Global Copper Alliance network and among the many professionals he advised on properties, applications and specifications of copper and copper alloys. He loved life in general, was keen on outdoor pursuits and cooking, and had a particular association with the sea, having grown up on the Isle of Wight.


He is survived by his wife, Fiona, and brother, Tim.
