Corrrosion is thermodynamically favoured, unstopable
chemical reaction that has very seriuos adverse economical
and ecological impacts. There are five methods by which
corrosion can be treated: (1) use of chemicals such as corrosion
inhibitors and biocides, (2) implementation of cathodic/anodic
protection, (3) application of coatings, (4) modification of the
design of the part to make it less vulnerable to the corrosive
eenvironmnet and (5) materials selction in the sense that
materials with better corrosion resistance will take the place of
more susceptibe ones.
There are basically two parrallel approaches to deal with
corrosion: One approach which is known as Corrosion
Management (CM) deals with the risk of corrosionin
purelytechnical and engineering terms while Corrosion
Knowledge Management (CKM) is a management approach
to be implemented by decision making managers. While
all the five methods to manage corrosion are more or less
costly, materials selction is with no doubt the most expensive
of the five becuae it often involves replacing the cheaper
material with lower corrosion resistance with the one that
is very expensive owing to its improved mechanical and
chemical properties. The difference in the cost could be
so huge that the overal cost of the project could become
doubled or tripled in terms of CAPEX (Capitial expenditure).
Increasing the CAPEX of a project is not an easy issue to
handle unless the project management is educated and
assured that the OPEX (operation expenditure) will be low
during the life cycle of the part. This is often a management
decision rather than a purely engineering ratification act
and for that a CKM mentality about the engineering risk
of corrosion in terms of its “Risk” and “Cost” must exist.
A company in which the top management is aware of the
risk of corrosion (in engineering terms) and cost of corrosion
(in managerial terms) will be more prone to accept the risk
of a higher CAPEX project in terms of materials selection
to minimise the consequenet OPEX than a company that
is considering corrosion something that” can be handled
anyway” down the line of the life cycle of the asset. In this
presentation, after a quick review of some economical and
environmental aspects of corrosion, the main framework of
CKM and its four principles will be introduced and discussed.
Speaker Biography
Reza Javaherdashti holds a double degree in Materials Science and
Metallurgical Engineering. In addition to being an internationally renowned
expert on microbial corrosion, He has several internationally referenced
booksandpapersonthesubject.Hehasover20yearsoffieldandacademic
experience as both a consultant and a researcher. He is the first scientist
who has applied Fuzzy logic in prediction the risk of microbial corrosion
successfully. While as an engineer corrosion is his passion, as a manager he
has grown interest in studies related to the cost of corrosion. He theorised
and formulated Corrosion Knowledge Management (CKM) for managers
and was the first who applied Future Studies to present a Futuristic model
for managers that had corrosion as its integral element.
