My supervisor researches NiTi and wants me to focus on corrosion studies. My senior is working on bare NiTi materials, conducting corrosion tests in simulated proton exchange membrane fuel cell electrolytes with good performance. Now, my supervisor wants me to find a surface modification method and conduct experiments. Since most literature is in the medical field, focusing on corrosion tests in simulated body fluids, I can't find references applicable to bipolar plates. I would greatly appreciate any advice you can provide!
