Erosion-corrosion properties of two novel Fe-based multicomponent alloys for marine applications
Abstract
The erosion-corrosion behavior in piping and drilling systems is a significant concern for their durability because of the presence of hard particles in fluids. Fe-based alloys are promising coatings materials for this kind of application, combining high corrosion and wear resistance and reducing costs. This work aims at studying the erosion-corrosion behavior of two novel Fe-based multicomponent alloys containing a low amount of Cr (11%at.) fabricated by spray forming and correlate the effect of the compositional difference on the microstructure and consequent erosion-corrosion behavior. Samples of two compositions, Fe61Cr11Mo8Nb4B16 and Fe61Cr11Mo8Ni4B16, were processed by spray forming deposition on an AISI 1020 substrate under N2 gas and temperature of 1750°C. The coating thicknesses were about 1-3mm. The microstructure was analyzed by scanning electron microscopy and X-Ray diffraction. Vickers microhardness was also evaluated, and values around 800 HV were found for both compositions. Polarization curves were carried out in a chloride-rich environment, Ecorr of -311 mV and icorr equal to 0.7 μA/cm2 were obtained for the Nb-containing composition, with better values when comparing to the Ni-containing and similar compositions found in the literature. Degradation tests were performed in a jet erosion-corrosion cell using commercial sand with a maximum flow rate of 5.5 m/s and jet angle of 45° and 90°. The potential fluctuated during the two hours of impingement, and a slight recovery was observed for both compositions. The measure of OCP after impingement indicates a better recovery capacity for the Nb-containing alloy, suggesting a better capacity of repassivation.
