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,micro-hardness,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.
