Abstract
The objective of this work was to determine the most appropriate temperatures for ion nitriding and nitrocarburising of AISI 316L austenitic stainless steel and ASTM A 890 Gr 5A super-duplex stainless steel, respectively, and to determine its influence on the corrosion resistance of these steels. Samples of steels were treated at 400 C, 450°C and 500°C and characterised by optical microscopy, X-rays diffraction and corrosion tests. Layer thickness increased with the treatment temperature for both steels. Potentiodynamic corrosion tests showed that for both steels, the nitrided and nitrocarburised layers at 400°C yielded either similar or superior corrosion behaviours when compared to the substrate, which is due to austenite or expanded ferrite presence (S phase).
