摘要：
This work presents corrosion resistance results of duplex stainless steels obtained through powder metallurgy starting from austenitic X2CrNiMo17-12-2 (AISI 316L), martensitic X6Cr13 (AISI 410) powders by controlled addition of alloying elements in the right quantity to obtain the chemical composition of the structure similar to biphasic one. In the mixes preparations the Schaffler's diagram was taken into consideration. Prepared mixes of powders have been sintered in a vacuum furnace with argon backfilling. After sintering rapid cooling was applied using nitrogen under pressure. Produced duplex stainless steels have been studied by SEM with EDS and light optical microscopy and X-rays analysis to determine obtained structures. Corrosion properties have been studied through electrochemical methods in 1M NaCl. (C) 2007 Elsevier B.V. All rights reserved.
