| 中文摘要: |
| 采用低温气体多元共渗技术在20钢表面同时渗入C、N、0三种元素，在材料表面形成了厚且致密均匀的渗层。利用X射线衍射和扫描电子显微技术测定了渗层相的组成以及渗层的表面形貌，结果表明：渗层以氧化物、氮化物和碳化物为主，且氮化物居多，渗层厚度约50 p.m。显微硬度测量结果表明，相对于原始材料硬度提高了4倍，这在工业生产中有广阔的应用前景。 |
| 英文摘要: |
| Performance of 20 steel was studied by low temperature gas multicomponent permeation technique. Carbon, nitrogen, oxygen were infiltrated into the material. The phase construction and micro-structure of alloying layer were investigated by XRD and SEM technique. The experimental results show that penetrated layer contains oxide, nitride and carbide. And the nitride is primary. The thickness of penetrating layer is about 50pjm. Compared with original material, the penetrated layer has much higher surface hardness. These properties have important significance and foreground in industry. |
