Abstract:
The field of Metallurgical Engineering includes a vast range of applications from tiny
mechanical components to massive construction applications. The service life of
metals is highly concerned and studied extensively. Among all industrial metals, plain
carbon steel plays a considerable role. Detecting the actual amount of corrosion has
become very vital and critical since the failures occurring due to corrosion is still a
substantial problem. Ultrasonic Testing is one of the modem methods which can be
used to identify the degree of corrosion of a metallic component accurately, without
causing any destruction. This study sought to contribute the field of metallurgical
engineering by identifying the effect of carbon content and ultrasonic attenuation
towards the corrosion of plain carbon steels. Plain carbon steel samples of different
carbon contents were allowed to corrode under accelerated environment and
periodically tested for ultrasonic attenuation and weight loss measurements. In
addition, corrosion penetration of the samples was examined under optical and
scanning electron microscopes. Observations were taken for both destructive and nondestructive
testing and were correlated so that, using this correlation, the degree of
corrosion can be determined in a non-destructive way without damaging the
components and hence the remaining service lifetime could be predicted.
