Peculiar Relationship of Plume Brightness and Hard Layer Formation in Atmospheric-Pressure Plasma Jet Nitriding

Peculiar Relationship of Plume Brightness and Hard Layer Formation in Atmospheric-Pressure Plasma Jet Nitriding

Irradiating the plume of atmospheric-pressure pulsed-arc plasma jet with nitrogen/hydrogen mixture gas enables to harden steel surface by nitrogen diffusion into steel. An important parameter is the hydrogen mixture ratio. Images of plasma-jet plume and formed hard layer for several hydrogen mixture...
