将45钢表面进行碳氮共渗试验，再将碳氮共渗层进行激光重熔试验。试验前后对比结果显示：碳氮共渗层表层出现的裂纹、黑带、组织粗大、网状化合物合成等组织缺陷已经得到很好的改善。

Firstly, the carbonitriding experiment has been carried out on the surface of 45 steel, and then the laser remelting experiment has been done. By contrast with the two experiments mentioned above,the bug of organization like crack, black belt, coarse-microstructure in carbonitriding layer has been eliminated by laser remelting, and the d...
