Abstract

This study investigates the erosion-corrosion behaviour of spark plasma sintered Fe-Cr-Ni relating additive and synergistic effects on the sintering temperature and time in mining and mineral processing industries. All tests were carried out using a rotating cylinder electrode system. The relative density has a relationship with the hardness values of the sintered alloys. The results linked the effects of the stainless steel sintering parameters (temperature and time) on the total mass loss, pure erosion, erosion-enhanced corrosion, and corrosion-enhanced erosion conditions. No correlation exists between the erosion-corrosion components and the densification mechanism since the porosity of the samples does not influence the sintered alloys behaviour. The surfaces indicated localized attack which increased with increasing time but decreased as the sintering temperature increased.
