高铬铸铁的冲蚀磨损性能研究
|
摘要
利用自制射流式气固冲蚀磨损实验机研究了耐磨材料高铬铸铁的冲蚀磨损性能。对该材料的组织和冲蚀磨损后的形貌采用扫描电镜(SEM)进行表征。分析了冲蚀角、冲蚀时间和冲蚀石英砂粒径对其冲蚀磨损性能的影响,研究了该高铬铸铁的冲蚀磨损机理。结果表明:60°冲击角作用下,冲蚀磨损最严重。随着冲蚀磨损时间的延长,冲蚀粒径的增大,高铬铸铁的磨损均加剧。
The erosion wear performance of high-chromium cast iron wear-resistant materials was studied by using the self-made jet-type gas-solid erosion wear tester. The microstructure and morphology of the material after erosion wear was characterized by SEM. The effects of erosion angles, erosion time and size of abrasive quartz sand on the erosion wear performance were analyzed. The erosion wear mechanism of the high chromium cast iron was analyzed. The results show that the erosion wear is the maximum under the impact angle of 60°. With the increase of erosion wear time and the erosion particle size, the wear of high chromium cast iron increases.
