Surface Treatment of Tool Steel in Controlled Plasma Nitriding Environment

Nitriding of tool steel was investigated in a controlled electron beam excited nitrogen plasma environment. The samples were nitrided in two distinct regions, a region with high plasma density and a region with low plasma density called the irradiated and non-irradiated region, respectively. The exp...
