| 摘 要： | 采用MSH型腐蚀磨损实验机,通过改变水砂两相流的冲击速度、含砂量和固相粒径等环境因素,研究了电沉积Ni-P非晶合金的冲蚀-腐蚀磨损行为。结果表明,电沉积Ni-P非晶合金的冲蚀失重率和冲蚀-腐蚀失重率均随着冲击速度、含砂量和固相粒径的增加而增大。与AISI 304不锈钢相比,电沉积Ni-P非晶合金冲蚀失重率和总失重率较高,但腐蚀失重率较低,也表现出了良好的抗冲蚀-腐蚀磨损性能。棒状Ni-P非晶合金镀层的冲蚀-腐蚀磨损,正面以砂粒挤压锻打造成的唇片和断裂为主,侧面以切削和犁削为主。

| Abstract: | With the variation of impingement velocity,sand content and sand size,erosion-corrosion behavior of amorphous Ni-P electrodeposits was investigated using model MSH erosion-corrosion equipment in this paper.Results show that the mass loss rates of erosion and erosion-corrosion increased with impingement velocity,sand content and sand size.Compared with AISI 304 SS,the mass loss rate of erosion and total mass loss rate of amorphous Ni-P electrodeposits are higher,but mass loss rate of corrosion is lower.And it also suggests amorphous Ni-P electrodeposits have good erosion-corrosion resistance.The erosion-corrosion mechanism of rod amorphous Ni-P electrodeposits is lip and fracture on its frontal side and cutting and furrow on its lateral side. |
