Austenitic stainless steels produced by laser powder bed fusion (L-PBF) are quite interesting materials owing to their specific microstructure consisting of dendrite walls built dislocations pinned many nano-oxides that involves significant strengthening without loss ductility. In this work, different plasma treatments were performed harden the surface 316 L steel manufactured L-PBF. The sample...

In this study carburizing and boronizing processes were applied to powder metallurgy steel specimens and the mechanical and tribological properties of the substrate and coatings were evaluated under various process conditions.&#10The specimens, made from industrial test pieces, were carburized in a powder pack for a duration of 2-5 hrs at 850-950 ˚C. Similar specimens were pack boronized for 4 ...

Aluminide coatings have been studied for many years because of their excellent corrosion resistance in oxidizing, sulfidizing and carburizing environments. One of the factors that inhibits their application is a lack of sufficient data about their potential benefits. In order to address this issue, model coatings are being fabricated using a chemical vapor deposition (CVD process on ferritic (F...
