Sintered duplex stainless steels (SDSSs) appear to be very interesting and promising materials that can be used in many industrial sectors. Ferrite improves material strength while austenite increases hardness and corrosion resistance. This study proposes a method to improve functional properties (e.g. hardness and wear resistance) by means of alloying the surface of the sintered duplex steel with Cr3C2 + 10% NiAl powder. The results of optical microscope metallography, SEM/EDX, XRD analysis and microhardness and wear resistance measurements are also presented. The surface alloying with Cr3C2 is a manufacturing method of surface layer hardening in sintered stainless steels and modification of surface layer properties such as hardness and coefficient of friction. |
