摘要
通过浆状镀铝在 T91 钢上制作了铁铝涂层。在 550 °C 的静态 LBE（铅铋共晶）条件下，评估了有涂层和无涂层试样的腐蚀行为。与无涂层试样相比，无论氧气浓度如何，涂层大部分都完好无损，并表现出很强的耐腐蚀性。这是因为涂层能在极低的溶解氧水平下在表面形成一层氧化铝保护膜。这种涂层在提高铁基合金在 LBE 中的耐腐蚀性方面具有重要的工程价值。
Enhancing corrosion resistance of T91 F/M steel in liquid lead-bismuth (LBE) by slurry FeAl coating
A FeAl coating was fabricated on T91 steel via slurry aluminizing. The corrosion behavior of coated and uncoated samples was assessed in static LBE (lead-bismuth eutectic) with two both high and low dissolved oxygen concentrations at 550 °C. The coating was mostly intact and exhibited great corrosion resistance compared to the uncoated specimens regardless of the oxygen concentration. That is because the coating can form a protective alumina film on the surface at extremely low dissolved oxygen level. This coating is of significant engineering value in enhancing the corrosion resistance of Fe base alloy in LBE.
