Abstract. Sintered duplex stainless steels are characterized by a two–phase structure consisting of approximately equal content of ferrite and austenite, which makes them very interesting materials for numerous applications. This study proposes a method to improve functional properties by means of alloying the surface of the SDSSs by the gas tungsten arc welding (GTAW) process, which it is an efficient method of surface modification in engineering materials. The results of a SEM/EDX optical metallographic microscope, XRD analysis and hardness are presented. The main assumption of this study was to analyze the microstructure and hardness of a surface layer of SDSS with different proportions of individual powders subjected to the alloying process by means of the GTAW method.
