In recent, accordingly as the concern about environment has increased, the plasma nitriding is attracting many people's attention as one of distortion-free processing. The plasma nitriding is the surface modification process in which nitrogen is penetrated and diffused in the surface by the high energy of plasma, and thus nitride layer of favorable surface properties is created.
But the plasma nitriding has the compound layer of brittleness. So the plasma radical nitriding is developed to renovate its problem.
plasma radical nitrding is a process which adds a small amount of NH₃ to the mixed gas of N₂ and H₂ used at the glow discharge plasma nitriding method.
we examined the plasma radical nitriding by changing the treatment temperature.
In the test of the surface properties of plasma radical nitriding and we measured the surface roughness and investigated the thickness of the diffusion layer.
we examined microstructure by using OM and we analyzed the X-ray patterns the wear properties in the plasma radical nitrided SKD61
We could observe the surface properties of plasma radical nitrided specimens, and confirm that the surface properties became improved in comparison with the plasma nitriding.
