| Abstract: | 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. |
