Systematic materials characterization of the Quench-Polish-Quench complex salt bath heat-treatment process (QPQ) surface modified 316L steel was investigated. The results reveal that the nitro-carburized sample surfaces consist of Cr 2 N/Ξ³Β΄-Fe 4 N and CrN/Ξ³-Fe, while the post-oxidized sample surface
