Fast testing of ambient temperature pitting corrosion in type 2205 duplex stainless steel by bipolar electrochemistry experiments

Electrochemistry Communications, 2020
Commercial grade type 2205 duplex stainless steel is resistant to localised corrosion at room temperature. With the application of bipolar electrochemistry, pitting and crevice corrosion can be probed at room temperature, with corrosion pits nucleated in

Pit growth kinetics of additively manufactured MoNi over-alloyed type 316L stainless steel

Journal of Materials Research and Technology, 2023
The microstructure and corrosion performance of wrought, laser powder bed fusion (LPBF), and MoNi over-alloyed LPBF type 316L stainless steel is compared. Adding Mo and Ni to LPBF 316L stainless steel resulted in ẟ-ferrite.
