dc.description.abstract |
Corrosion of metals makes a large impact on the
remedial actions to prevent structures,
corrosion the corrosion that
economy of a country. Therefore, it is important
machinery and vehicles from corrosion. Among the various types of
occurs in the atmosphere is known as atmospheric corrosion and it accounts for
more failures than other types oj corrosion. To take preventive actions against atmospheric corrosion of
metals, it is essential to study the corrosivity of the atmosphere by analyzing factors that influence it. The
corrosivity of the atmosphere mostly depends on several atmospheric variables, such as relative humidity,
temperature, rainfall, chloride deposition rate, pollutant gases like nitrogen and sulfur oxides.
In order to study the severity of the atmosphere which promotes the
used structural materials mild steel, stainless steel 304 and 316
conditions. Two corrosion test panels
to take
metal corrosion three types of commonly
were exposed in two different atmospheric
placed in two geographical locations and loss of weight due to
corrosion was continuously measured in all three types of metals. The atmospheric variables in the two
locations were also continuously recorded. Finally, these data were fitted with the power model in order to
predict the rate of corrosion under particular atmospheric conditions. With the predicted corrosion rate under
a particular atmospheric condition it is possible to take necessary> preventive measures during the design or in
the service of metallic structures, machinery and vehicles etc. The broad aim of this research work is to collect
adequate data to develop a corrosion model to predict the corrosion rate in any atmospheric environment in
Sri Lanka using measured atmospheric variables and thereby establish a 'corrosion map'for Sri Lanka. |
