The effects of mechanical properties, chemical composition, microstructure, and surface morphology of duplex stainless steel surfacing layers as well as the parameters of serving environment on the cavitation erosion behavior of duplex stainless steel surfacing layers were introduced. The analysis shows that by regulating the alloy composition and improving the microstructures, modified duplex stainless steel surfacing layers with excellent cavitation erosion resistance are expected to be prepared, which will provide materials and engineering schemes for the development of marine industry in China. 双相不锈钢 堆焊层金属 空化腐蚀行为 duplex stainless steel surfacing layer cavitation erosion behavior TG172;TG457.11 国家自然科学基金资助项目(51879089);中央高校基本科研业务费专项资金资助(B200204036) 2022-03-08 9 50
