Abstract
The double-pressing, double-sintering process results in a closed, round pore morphology. Samples obtained by this process exhibit a clear passive behavior in an H2SO4 environment. The noble alloying elements: Au, Ag, Pd, Pt, Ni and Cu enhance the self-passivation process, and enable passivation even in samples with some degree of open porosity, obtained by a single process of hot pressing and sintering. Stainless steel samples without noble alloying additions were not passive after a single process of hot pressing and sintering. Some of the double-pressed, double-sintered samples exhibit a second anodic maximum at a potential range of +500-575 mv(SCE), which is attributed to a σ-phase and α-ferrite.
