| 摘 要： | 水轮机用铸造超低碳马氏体不锈钢遭受着泥砂冲刷和腐蚀的双重作用.在生产条件下将经过表面改性处理的纳米SiC粉体加入到铸造超低碳马氏体不锈钢中,分别在加与不加NaCl的两种水砂粒介质中进行磨蚀试验,研究纳米SiC粉体加入量对其耐磨蚀性能的影响.结果表明:纳米SiC粉体强化处理后马氏体不锈钢表现出优越的耐磨蚀性能,其材料失重形式主要为韧性断裂,当SiC加入量为0.1％时,在水砂粒和3.5％NaCl水砂粒中磨蚀率分别降低了90％和86％.

| Abstract: | The turbine steel has to suffer the dual effects of sediment erosion and corrosion.The nano-SiC powders were poured into the melt for ultra-low carbon martensitic stainless steel,and the abrasion test was carried out in sand-water mixture with and without NaCl to study the effect of nano-SiC powder addition on corrosion resistant properties of the steel.The results show that the martensitic stainless steel strengthened by nano-SiC powders shows superior abrasion performance.When the addition of SiC powders ... |
