摘要
利用Nd:YAG固体脉冲激光对GCr15钢样品表面进行了激光氮化处理,获得了高硬度、高耐磨损、表面致密均匀的氮化铁改性层,并对改性层进行了XRD谱分析和表面及剖面显微形貌分析、表面硬度及硬化深度和磨损率等的测量。同时对GCr15钢表面激光氮化机理进行了分析和研究。
Pulse laser nitriding of GCr15 steel was studied. The experimental results show that a high hardness, good wear resistance, compact and uniformity hard layer of iron nitride was obtained. The microstructure, phase constitution, microhardness, depth and wear properties of the layer were determined and analyzed, and the pulsed laser nitride mechanism on the surface of GCr15 steel was discussed.
