That the old, largely hand-worked metal of about 30 years ago is
superior in rust-resisting quality to the usual modern steel and iron is
attested by the recorded evidence of a large number of observers.
On Paints and Corrosion Inhibitive Pigments
The many theories which have attempted to explain the rusting of
iron during the last century have stimulated a large amount of
original research on the relation of various pigments to the corrosion
problems. In the course of the investigations undertaken, the
subject of protective coatings for iron and steel was naturally
brought into prominence and received a considerable amount
of attention.
The study of protective coatings for iron has led many paint
manufacturers, as well as scientific investigators, to make closer studies
of the causes of corrosion. It is evident that the electrochemical
explanation of corrosion must have a direct bearing on paint problems.
1.3 Needs for Corrosion Education
The specific needs for corrosion education vary greatly with the level
of education required, the functions expected of the personnel, and of
course the applications where corrosion is a concern. In order to
indicate the suitability of the various teaching aids and texts for
particular types of training, four categories of corrosion personnel
based upon their particular activities have been identified by the
European Federation of Corrosion (EFC).
• Group A: corrosion scientists and engineers
• Group B: technologists
• Group C: technicians
• Group D: operatives
In real-world situations, all corrosion personnel would, of
course, work toward the solution of often very specific corrosion
problems and there will be considerable overlap between the tasks
assigned to individuals. Any person working primarily in one
group will probably have interests and activities in other groups.
The distinction between these groups is therefore more one of
perspective, rather than level of skills. When designing a corrosion
training course or program, it should be realized that while the
training material should be broadly based and cover all major
aspects of corrosion and protection, there will inevitably be some
emphasis put on the lecturer’s field of interest and expertise. There
could also be some specific requirements depending on the trainee’s
type of work, for example, aeronautical, automotive, oil and gas,
and medical.
