The present study has been conducted to investigate the interaction between corrosion and erosion processes and to quantify the synergism in realistic flow environments, including sudden pipe constrictions, sudden pipe expansions, and protrusions. Tests were conducted on AISI 1018 carbon steel using 1% wt sodium chloride (NaCl) solution purged with CO 2 as the corrosive media and silica sand as the erodent.The experiments were designed to understand whether erosion enhances corrosion or corrosion enhances erosion and to evaluate the contribution of the individual processes to the net synergism. It was observed that erosion enhances corrosion and corrosion enhances erosion, with each contributing to significant synergism; however, the dominant process was the effect of corrosion on erosion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
