Abstract
Erosion-corrosion is one of the most common problems in process industries such as the mineral processing, mining, and chemical industries. For decades, erosion-corrosion in many industries was due to transporting process fluid over long and short distances in a pipeline. This common problem in industries has resulted in catastrophic failure of equipment and loss of mechanical efficiency, hence, this phenomenon has gained attention in the field of engineering research. This work investigated the synergistic effect of erosion-corrosion on 2205 duplex stainless steel in mine water. The objectives of the study were to (i) determine the impact of flow velocity on the erosion-corrosion behaviour and on components such as pure erosion, erosion-corrosion synergy, erosion-enhanced corrosion ( ) and corrosion-enhanced erosion ( ) in mine water, (ii) evaluate the mechanical stability of the 2205 duplex stainless steel before and after exposure to the erosion-corrosion and pure-erosion environments, and (iii) characterise 2205 duplex stainless steel before and after exposure to the studied environments. The erosion-corrosion components were determined using the gravimetric and electrochemical measurements techniques. ..
