The aim of the current work was to analyse impact salt bath nitriding on behavior tribological characteristics and surface microstructures AISI 316L stainless steels. Nitriding carried out at 580°C for 10 h. tribological, structural before after compared. microstructures, characteristics, as well its hardness, were investigated using optical microscopy (OM), X-ray diffractometer (XRD), profilom...
