Abstract
We investigate relationships between the elemental composition and microstructure of DSS 2205 materials and their acid corrosion behaviour (4â¯M HCl) in the absence and presence of inhibitor (naphthylmethyl quinolinium chloride, NMQCl). Without inhibitor, the corrosion rate decreases with increasing Ni and austenite content. The austenite content is mainly controlled by Ni and N contents. In the presence of inhibitor, at concentrations 4-11.1â¯mM, the corrosion rate decreases with increasing Ni content and inhibition efficiencies are 94.5-99%. When the inhibitor dosage is 20â¯mM, the corrosion rate becomes independent of Ni content and inhibition efficiencies are â¥99%.
