| Abstract Scope |
The aim of this work was to investigate whether the same positive effect of nitriding could be obtained for austenitic stainless steel AISI 316 L and maraging steel MS300 that were both additive manufactured using selective laser melting and appropriate heat treatments or aging, selectively, and low-temperature plasma nitriding at different temperatures. This study was designed to better understand the microstructure of additive-manufactured and low-temperature plasma-nitrided surface as well as developing a nitride and a diffusion layer. The comparison of the wear and corrosion resistance, the microhardness and the microstructure changes of the additive-manufactured steels in different post-treated conditions with commercial steels was carried out. It was found that the post-treated low-temperature plasma nitriding improves the wear and corrosion resistance of the additive-manufactured samples. Finally, we were able to explain the microstructures at the nano level as well as correlating the wear and corrosion properties. |
