dc.description.abstract |
The field of Metallurgical Engineering associated with the estimation of the service
life of corroded structural members which has been studied in extensive detail, the
world over. Most of the research work in this area have focused on the general attack
(uniform corrosion) faced by steels across a range of atmospheres. This study sought
to contribute to this field by examining whether the penetration of corrosion beyond
the general attack has a significant effect on the load-bearing capacity of mild steel.
Mild steel samples were corroded in an aggressive atmosphere over a 5-month period,
subjected to periodic tensile testing and corrosion mass-loss analyses and examined
under optical and electron microscopy. Through the identification and measurement
of the penetration of corrosion using scanning electron microscopy, this research
managed to correlate corrosion mass-loss and tensile load-loss data with said
microscopic measurements. The results showed that the actual fracture loads deviated
negatively from the expected load- bearing capacity, which was determined through
conventional methods. This deviation showed a close correlation to the increase of
penetration of corrosion with time. As a result of this correlation, the research
concluded that allowances ought to be made for the penetration of corrosion when the
remaining service life of corroded load-bearing members has to be calculated more
accurately. |
