| 摘 要： | 为拓宽粉末冶金材料的应用领域，研究了一种铁基粉末烧结材料，并对其进行了高频感应淬火表面处理。用扫描电镜（SEM）观察了材料表面硬化层的组织形貌，用显微硬度计测定了材料横截面的显微硬度，在磨损试验机上进行了干滑动摩擦磨损试验。结果表明，经高频淬火后，在该铁基粉末冶金材料表面得到了针状马氏体相变硬化层，材料表面硬度显著提高，因而耐磨性也得到明显提高，同时还扩大了铁基粉末冶金材料的应用载荷范围。该材料可用于制造汽车齿轮、凸轮等零件。 |
| 关 键 词： | 铁基粉末冶金材料 高频淬火 耐磨性 |

| Abstract: | A kind of high frequency hardened iron base PM materials was studied. The case hardened structure was examined by SEM,mierohardness of the cross-section was determined by microhardness tester,and friction and wear test was performed in a tribological rig under dry sliding condition.It was shown that needle-shaped martensite hardened case could be obtained in iron base PM materials by high frequency hardening,as a result,the hardness could be remarkably increased and wear resistance could be remarkably improved at a widen applied load range. This kind material can be used to manufacture automotive parts as gear,cam,etc. |
| Keywords: | iron base PM materials high frequency hardening wear resistance |
