Effect of electro discharge machining (EDM) on the AISI316L SS white layer microstructure and corrosion resistance [PDF]

, 2012
The localised corrosion resistance of austenitic stainless steels is strongly influenced by the quality of finished surface. EDM machining induces substantial changes by the high thermal gradients generated by electric sparks.
