摘要
采用微观形貌观察以及失重法研究了不同转速下循环泵叶轮材料高铬铸铁Cr30A在模拟湿法脱硫浆料环境中的腐蚀磨损行为,研究了转速对高铬铸铁腐蚀磨损行为的影响以及腐蚀-磨损交互作用。结果表明,腐蚀磨损中机械磨损占主导作用。腐蚀-磨损交互作用程度随转速不同而产生变化,当转速为400 r/min时,腐蚀磨损试样表面无氧化膜,腐蚀磨损交互作用量占总腐蚀磨损量的48.73%,表现为协同作用;当转速为1200 r/min时,腐蚀磨损试样表面存在致密氧化膜,腐蚀-磨损交互作用量为负,表现为对抗作用。腐蚀-磨损交互作用是影响材料耐磨蚀性能的重要因素。
        The erosion wear performance of Cr30A high chromium cast iron in a simulated circulating pump operation condition with slurry related to wet desulfuration process for thermal power plant, was investigated by means of mass loss test and microstructure examination. The result shows that with the increasing rotation speed, the mass loss of the steel significantly increases. The wear component is the main fraction of the total amount of corrosion-wear. When the rotation speed is 400 r/min, there is no oxide scale on the surface of the test steel sample. The component of interaction for corrosion and wear may be accounted for 48.73% of the total corrosion-wear, implying that there existed synergistic effect of the two. When the rotation speed is 1200 r/min, there is a dense oxide scale on the steel surface, the component of corrosion-wear interaction is negative and it seems that the two processes are antagonistic. The interaction between corrosion and wear is an important factor affecting the wear resistance of materials.
