The main method for production of structural materials from metallic powders with addition or without addition of non-metallic powders is powder metallurgy (PM). This method is based on forming and sintering processes. The PM method consists of a small number of process steps and insignificant energy consumption, which allows to production of complex shape components, with great precision in dimensions and surface quality. Taking into account the above advantages, interest in sintered duplex stainless steels (SDSSs) is growing, which are characterized by two-phase microstructure consisting of ferrite and austenite. Such combination of properties makes the SDSS a very attractive material for numerous applications. As is well known, the chromium carbide coatings improve functional properties (e.g. hardness and wear resistance). The main purpose of this study was to examine the effect of chromium carbide coating on the properties of SDSSs. The multiphase sinters were prepared from two types of water-atomized steel powders: 316L and 409L. The technique of atmospheric plasma spraying (APS) was used to deposit Cr3C2–NiAl powder on SDSS surface. Additionally, it was carried out alloying the surface of the SDSS by gas tungsten arc welding (GTAW) process at current intensity 50 A. Light microscopy and scanning electron microscopy (SEM/EDS) were performed in order to determine the microstructure of SDSSs. The results of hardness and wear resistance measurements are also presented. The applied chromium carbide coatings cause hardening in SDSSs and modification of surface layer properties, such as coefficient of friction. Furthermore, the main assumption for this investigate was to analysis the microstructure and hardness of surface layer of SDSSs with different proportions of powders as a result the alloying process.

Powłoki z węglika chromu poprawiają właściwości funkcjonalne materiałów takie jak twardość i odporność na zużycie. Głównym celem pracy była analiza wpływu powłoki z węglika chromu oraz stopowanej warstwy wierzchniej na właściwości spiekanych stali nierdzewnych typu duplex (SDSSs). W celu wytworzenia powłoki z proszku Cr3C2–NiAl na powierzchni SDSS zastosowano natryskiwanie plazmowe w warunkach atmosferycznych (APS). Dodatkowo przeprowadzono stopowanie powierzchni SDSS łukową metodą spawalniczą GTAW przy natężeniu prądu o wartości 50 A. W celu określenia mikrostruktury SDSS wykonano badania za pomocą mikroskopii świetlnej i skaningowej mikroskopii elektronowej (SEM/EDS). Przeprowadzono analizę wyników pomiarów twardości i odporności na zużycie w powiązaniu z analizą mikrostruktury i warstwy powierzchniowej SDSS powstałej w wyniku procesu stopowania.
