Study of the synergistic effects of fatigue and corrosion in CA6NM steels and welds for hydraulic turbine applications

In this project we propose to evaluate the synergistic effects of fatigue and corrosion to further understand the degradation mechanism of the alloys used by our partner. This will help the partner defining their total cost of ownership & develop mitigating corrosion strategies to ensure long term sustainability of their infrastructure. Specifically, we will i) study two types of soft martensitic stainless CA6NM (13%Cr-4%Ni) cast low carbon steel (as received and welded), ii) quantify their localized corrosion properties, iii) study the synergistic effect that static applied mechanical stress has on the corrosion behavior.
