Abstract

Hot pressed and sintered stainless steel samples are usually active in a H₂SO₄ environment, at ambient temperature and corrode up to total loss. The double pressing, double sintering (DPDS) process results in a closed, round pore morphology. Samples obtained by this process exhibit a clear passive behavior in a 1 N H₂SO₄ environment. The pore morphology of the sintered stainless steel has a crucial role in its environmental behavior. When a closed pore morphology is achieved, its behavior is similar to wrought stainless steel. The noble alloying elements enhance the self passivation processes, and enable passivation in samples with some degree of open porosity.
