Determination of Atmospheric Salinity at Kalpakkam Using Wet Candle Experiment

摘要

The extent of chloride content in the atmosphere has a direct influence on the susceptibility to stress corrosion cracking and pitting corrosion of austenitic stainless-steels. This report presents the results of a systematic evaluation of the chloride content in the Kalpakkam's coastal atmosphere, carried out over a period of two years, using a wet-candle experimental set up (as per IS - 5555). The results have been correlated with other atmospheric parameters like relative humidity, temperature and rainfall. It has also been shown that atmospheric salinity has a direct bearing on the extent of corrosion of samples exposed to this atmosphere. (ERA citation 11:020910)
