Surface modification of martensitic stainless steel AISI 420 was achieved using friction stir processing (FSP) with a W–Re pinless tool. The microstructure, hardness and corrosion resistance of the FSPed 420 fabricated at various traverse speeds (150 to 250 mm/min) of the tool were investigated and compared with annealed and conventionally …
Decarburization deteriorates the surface mechanical properties of steel. It refers to the loss of carbon from steel's surface when exposed to an open-air environment in elevated-temperature conditions. Despite the short interaction time and fast thermal cycle of the laser surface-hardening process, decarburization may still occur. This paper …
