- Description
- Steel structures are known to corrode in the presence of seawater and inert particles (sands, rusts, coal, iron ore, etc) of different sizes. Previous work by others has shown that particle size can influence corrosion mass loss rates. However, it remains to be seen whether particle size has an influence on the long-term corrosion mass loss and pit depths under fully immersed seawater conditions. This paper presents experimental work aimed at studying this behaviour. Mild steel coupons were buried in three different particulate media (sand, a coarse silicon carbide, and a fine silicon carbide) and immersed in seawater for up to a year. Pitting depth and extent were found to be independent of particle size. Mass loss was found to increase with an increase in particle size. The progression of corrosion pit depths and mass loss with time are consistent with the initial stages of the bi-modal trend for steel corrosion.
