This study presents the findings concerning the effect of remelting on microstructure and selected properties of sintered duplex steel. It was demonstrated that the methods of processing lead to homogenization and elimination of porosity in the surface layer of sinters, which substantially affects their properties (surface roughness, microhardness and resistance to friction wear). It was found that the degree of tribological wear in the steel used in the study depends primarily on the microstructure and phase composition and less on porosity.
