Comparison of erosion, corrosion and erosion-corrosion of carbon steel in fluid containing micro and nano size particles

Comparison of erosion, corrosion and erosion-corrosion of carbon steel in fluid containing micro and nano size particles
Comparison of erosion, corrosion and erosion-corrosion of carbon steel in fluid containing micro and nano size particles
This work presents the results of an experimental study on surface damage due to erosion, corrosion and interactive effect of them in seawater in the presence or absence of 1g/l suspended nano-size as well as micro-size Al2O3 particles. Erosion and erosion-corrosion tests have been conducted on low carbon steel targets, using a rotating cylinder system. It is found that nano- and micro-size particles act as inhibitors and decrease the pure corrosion rate in comparison to the base fluids free of these particles but over time the inhibitory effect of microparticles is lost. The presence of microparticles causes more severe steel erosion than the seawater, whereas the difference between nanofluid and seawater is not significant. In spite of nanoparticles effects on pure corrosion and net erosion, mass loss due to erosion-corrosion in a nanofluid is much higher that the base fluid but is less than the fluid containing micro-size particles.

Abstract

This work presents the results of an experimental study on surface damage due to erosion, corrosion and interactive effect of them in seawater in the presence or absence of 1g/l suspended nano-size as well as micro-size Al2O3 particles. Erosion and erosion-corrosion tests have been conducted on low carbon steel targets, using a rotating cylinder system. It is found that nano- and micro-size particles act as inhibitors and decrease the pure corrosion rate in comparison to the base fluids free of these particles but over time the inhibitory effect of microparticles is lost. The presence of microparticles causes more severe steel erosion than the seawater, whereas the difference between nanofluid and seawater is not significant. In spite of nanoparticles effects on pure corrosion and net erosion, mass loss due to erosion-corrosion in a nanofluid is much higher that the base fluid but is less than the fluid containing micro-size particles.
