Title: Nitrogen enrichment of AISI 409 stainless steel by solution heat treatment after plasma nitriding
Author: E. M. BERTON, J. C. K. das NEVES, M. MAFRA, P. C. BORGES

Abstract: This work presents a new treatment for ferritic stainless steels. The Solution Heat Treatment after Plasma Nitriding (SHTPN) of AISI 409 samples resulted in a nitrogen-rich martensitic layer, thicker than 600 μm, and with 500 HV (4.90 GPa) until 200 μm. Polarization curves prove that surface hardening has not compromised corrosion resistance.

Keywords: AISI 409 stainless steel, nitrogen enrichment, surface engineering, Solution Heat Treatment after Plasma Nitriding (SHTPN)
