Plasma nitrocarburizing of austenitic stainless steel at 420 °C is typically applied to improve the surface hardness and wear resistance without impairing the corrosion resistance of the material. Recently, based on the active screen technology a no

The feasibility of a novel approach of plasma nitrocarburizing with active screen (AS) made of carbon-fiber reinforced carbon (CFC) has been demonstrated in a comparative study of two types of AS material, steel and CFC, under similar process conditi

The active screen plasma nitrocarburizing (ASPNC) technology is an extension of the ASPN method in that carbon-bearing gases such as CH4 are admixed to the N2-H2 process gas. Besides process gas composition and working pressure, a bias power applied

Low-pressure pulsed DC N2-H2 plasmas with admixtures of CH4 were investigated in a comparative study in two different types of reactors, (i) a cylindrical industrial scale active screen plasma nitriding (ASPN) reactor and (ii) a laboratory scale plas
