Résumé : |
A corrosion study with respect to contaminants (water soluble salts I ike sulphates, ch lorides and nitrates etc.), design of the components (macro and micro defects developed due to improper design and physico-chemical behaviour of coatings (adhesion, permeation of air and moisture) etc. was done by several scientists and found that these elements prove to be the deciding factors in rate of corrosion. The presence of soluble salts (chloride, sulphate & nitrate) and their effect of the coating-metal interface was studied along with the chemistry of coating, water and oxygen permeabi I ity, coating th ickness and metal surface preparation. The macroscopic defects, caused due to improper design ing, handl ing, etc. also causes corrosion. The surface anomalies have their own rote in deciding the coating life. There are some coating systems which can reduce or postpone corrosion mechanism. |
