Abstract
Nitrided 304L stainless-steel coatings were deposited on low carbon steel substrates by dc-magnetron sputtering in a reactive atmosphere of argon and nitrogen. The nitrogen partial mass flow (pN2) was varied linearly from 0% to 100% resulting in a nitriding of the stainless-steel coatings with nitrogen concentrations up to 46 at%. Positron annihilation spectroscopy is used to characterize the defect structure of the coatings. The remarkable evolution of the defect structure with increasing pN2 is discussed.
