Abstract

In this study, AISI 420 grade martensitic stainless steel was subjected to low temperature gas nitriding in a fluidized bed reactor. Penetration of nitrogen into the steel produced a CrN free surface layer (about 15 μm thick) consisted of iron nitride (ε and γ ′) and expanded martensite (α_N). Formation of this surface layer accompanied not only by remarkable increase in the surface hardness, but also caused significant improvement in wear and corrosion resistances.
