Interstitial Hardening of Stainless Steel for Enhanced Corrosion Resistance for Naval Applications
Abstract
Collaborative work between the Corrosion Science group at NRL and the Dept. of Materials Science and Engineering at CWRU had demonstrated that a novel low temperatures "paraequilibrium" interstitial hardening process led to a dramatic improvement in corrosion resistance of austenitic stainless steels in marine environments. This prior work had beenconcerned with carburization, mostly using carbon monoxide (CO) as the carbon somce.Inasmuch as many commercial hardening processes involve nitridation or nitrocarburization, one of the principal aims of the program was to establish whether interstitial hardening treatments using nitrogen in isolation, or in combination with carbon, could likewise enhance corrosion resistance of austenitic stainless steels, and if so, to define the optimum treatment conditions.
