Influence of NaCl solid deposit on the high-temperature corrosion behavior of additively manufactured alloy 625
Source abstract
Abstract
Additive manufacturing (AM) process is used to elaborate deposits of alloy 625 on a low-alloy ASTM A387 steel substrate. The effect of NaCl deposit on the alloy corrosion behavior is investigated at 800°C. The presence of NaCl deposit conduct to an important corrosion of the alloy with the formation of a thick corrosion scale and numerous voids in the metal beneath the scale. The presence of gaseous metal chlorides lead to the establishment of a self-sustaining active corrosion mechanism. Thermodynamic calculations allow to assess chlorine influence on alloying elements and to understand their contribution in oxide layers and voids formation.
