Surface properties of nitrided layer on aisi 316l austenitic stainless steel produced by varied time low-temperature thermochemical treatments
Recently, there are several attempts to improve the surface properties of AISI 316L by the mean of thermochemical treatments. The expected result is a layer on the surface termed expanded austenite which is supersaturated with nitrogen and carbon and this structure is responsible for the higher hard...
