| Abstract: | The impact abrasive wear property of Fe-B-C alloy was studied by using MLD-10 abrasive wear testing machine, compared with the same property of high chromium cast iron. The wear mechanism of Fe-B-C alloy was discussed based on the analysis of scanning electron microscope （SEM）. The results show that： First, the hardness, impact toughness and wear resistance of Fe-B-C alloy are equivalent to that of high chromium cast iron, so the Fe-B-C alloy has great performance price ratio. Second, the wear mechanism of Fe-B-C alloy is a mixed abrasion mechanism, mostly micro cutting, with micro-fracture and micro-ploughing coexist. |
