After attending this course delegates should be able to cost effectively prevent corrosion at the design stage by application of the knowledge gained. Suitable for: The course is aimed at engineers of all disciplines including trainees, consultants, architects and educators. The course will be of particular value to those who are suppliers of metals and alloys, and to manufacturers of corrosion resisting materials such as paint and zinc. It will also be of value to those involved in service industries (electrical, gas and sewerage) and construction, mining, marine and especially galvanisers.

Course programme
A two day course aimed at practicing engineers and designers interested in the prevention of corrosion by selection of appropriate materials and coatings. The basic theory of corrosion is presented in an easy to understand manner. Marine, building, automotive, and chemical sectors are used to illustrate the application of corrosion resisting materials. Coatings, anodic and cathodic protection are examined in detail. Interesting case studies are presented to demonstrate typical problems and solutions.
Corrosion in industrialised nations costs vast amounts of money every year. Typically 3.5 to 5.0% of the GNP. Existing corrosion prevention technology, correctly implemented can reduce these costs by up to two thirds.
