چکیده انگلیسی
Long-term corrosion tests for up to â¼13,194 h on 1.4970 (15-15 Ti), 316L and 1.4571 austenitic steels were carried out at 400 °C in flowing LBE (2 m/s) with 10â7 mass% dissolved oxygen. The steels show general slight oxidation (Cr-based oxide film) along with local, pit-type solution-based corrosion attack. The incubation time for pit-type attack is â¼4500 h. After â¼13,194 h, the maximum pit depth observed was â¼14, 23 and 57 μm for 1.4970, 316L and 1.4571, respectively, that corresponds to local corrosion rates of â¼6, 10 and 26 μm/year. At 450 °C and 550 °C, the corrosion rates are ranged in between â¼120â220 μm/year and â¼500-3000 μm/year, respectively. Corrosion appearances and mechanisms are discussed.
