Abstract

AISI 316L sintered samples, with porosities ranging from 9 to 40 %, and without alloying losses at the surface, have been prepared. Those samples, along with conventional (rolled) steel samples, have been subjected to electrochemical and immersion corrosion tests. According to porosity size quantitative measurements, before and after corrosion tests, two corrosion mechanisms, general and pitting, are proposed depending on the initial porosity.
