本文通过对高铬铸铁(15Cr3Mo)在销盘磨损、冲击磨损、腭式破碎机腭板磨损条件下的磨损形貌观察,分析了磨屑的形成过程。并结合高铬铸铁磨损试样的表面及亚表面观察。探讨了高铬铸铁中碳化物的失效方式及对磨损过程和磨损机理的影响。最后提出了高铬铸铁的磨粒磨损过程示意图及选用高铬铸铁的依据。
In this paper, wear of high chrome cast iron (15Cr3Mo) under pin-plate wear, impact wear and palatal jaw pavement wear was observed and the forming process of wear debris was analyzed. Combined with high chromium cast iron wear the sample surface and subsurface observation. The failure mode of carbide in high chromium cast iron and the influence on the wear process and wear mechanism were discussed. In the end, a schematic diagram of abrasive wear process of high chromium cast iron and the basis for selecting high chromium cast iron are put forward.
