Abstract
This study investigated the influence of the additions of various amounts of ruthenium (Ru) and palladium (Pd) on the electrochemical behaviour and corrosion resistance of 304 stainless steel in a number of different organic acid media, by measuring their electrochemical polarization behaviour in these media at room temperature. The analysis of the results obtained showed that the alloyed sample containing almost equal amounts of Pd and Ru (PdRu) exhibited more corrosion resistance in all the organic acids studied compared to the rest of the other samples. It was observed that the PdRu alloy sample was most susceptible to corrosion in lactic acid and least in citric acid. All the Ru alloyed samples (Ru1, Ru2 and Ru3) corroded less in lactic acid medium and more in oxalic acid (Ru1 and Ru2) and citric acid (Ru3). It can be confirmed that the addition of Pd and Ru in the alloyed samples considerably improved the corrosion resistance of these alloys.
