Effect of Cold Work on Cavitation Resistance of an Austenitic Stainless Steel Coating Open
Machining procedures of welding deposits are usual and result on cold work hardened surfaces. The cold work effect on cavitation erosion of an austenitic stainless steel surface is assessed. FeCrMnSiB coatings were processed by PTA on AISI…
