Plasma Surface Metallurgy of Materials Based on Double Glow Discharge Phenomenon [PDF]
arXiv, 2020 Plasma Surface Metallurgy/Alloying is a kind of surface metallurgy/alloying to employ low temperature plasma produced by glow discharge to diffuse alloying elements into the surface of substrate material to form an alloy layer. The first plasma surface metallurgy technology is plasma nitriding invented by German scientist Dr.
