Resumo
Pre-sintering for removal of lubricants is one of the most important steps in processing of
powder metallurgy materials to achieve corrosion resistance. This is often the most neglected step
in the sintering process. Incomplete removal of these organic compounds may result in sensitization
of sintered parts. The aim of this study is to investigate the effect of lubricant removal process on
the corrosion resistance of sintered AISI 304 L stainless steel filters. Pre-sintering was carried out at
450° C and sintering at 1150° C. As lubricant, 1% wax was used. The corrosion resistance of
sintered samples was evaluated by polarization and tests, optical and scanning electron microscopy.
The results showed that lubricant removal was not complete and during sintering sensitization of the
stainless steel occurred decreasing the localized corrosion resistance of the stainless steel.
