| 摘 要： | 在50钢表面进行等离子渗Cr，然后进行等离子超饱和渗碳、淬火及回火处理，获得表面强化层，并对处理后的材料进行拉伸试验和断口形貌观察。结果表明：50钢经表面强化处理后，表面硬度迭HV1000以上，抗拉强度得到了显著提高，极大地改善了其力学性能。表面强化层均存在解理台阶；而未经过处理的基体表面存在大量韧窝。

| Abstract: | The element Cr was permeated into the surface of 50 steel using plasma surface alloying technology. Surface intensifying layer was achieved by plasma supersaturated carburizing, quench and temper treatment subsequently. Tensile experiment was carried out and the fracture appearance was observed. The results showed that the surface hardness of 50 steel reached 1000HV above; its tensile strength had been obviously increased and mechanical property was largely improved. In addition much cleavage step appeared on the fracture appearance of the layer, while a large amount of dimple appeared on the surface of the substrate. |
