【Abstract】 The lead-bismuth fast reactor uses liquid lead-bismuth alloy as the coolant, which has high safety and promising development prospects as Generation Ⅳ. In this study, we mainly focus on the lead-bismuth corrosion resistant coatings. The Stellite alloy coatings are prepared on the austenitic stainless steel substrates, whose composition and microstructure are analyzed. The lead-bismuth corrosion resistance experiment of the coating is carried out to analyze its structural integrity, mechanical properties, surface oxide layer, and phase composition changes. The lead-bismuth corrosion resistance of the Stellite alloy coating is evaluated by characterizing the microstructure and mechanical properties to provide theoretical and technical support for the engineering application of the lead-bismuth fast reactors.更多还原
