The Characteristic of Surface Layers on Austenitic Stainless SteelAfter Glow-discharge Nitriding Process.
Abstract
This paper presents investigation of surface layers. The diffusion layers were produced by using different parameters of reactive atmosphere (N2:H2). The research of the surface layers was performed using scanning electron microscope (SEM). The results of energy dispersive X-ray (EDX) analysis and X-ray diffraction (XRD) analysis are presented. Research reveals the influence of chemical constitution of reactive atmosphere on the change of properties of nitrided layers. Technology of low-temperature glow-discharge nitriding process in case of austenitic stainless steel provides a possibility to achieve the most effective strengthening of austenite influence on mechanical properties. In case of glow-discharge nitriding process,present work is oriented to low-temperature processes of treatment. The aim of this approach is to obtain supersaturated microstructure of nitrogen with elimination of nitride precipitates. This nitriding process is intended to provide a beneficial influence not only on the microhardness and abrasion resistance but also on the corrosion resistance. Research works indicate beneficial influence on abovementioned properties of austenitic stainless steel at temperature of 450 [0C]. Present work analyses nitrided layers by using different parameters of treatment. The aim of this research is to optimize parameters of the considered process.
