Hi everyone, Noob to the forums, but forum junkie in different hobbies. Anyways, my senior project is to identify appropriate bench test to characterize degradation behaviors of magnesium-based alloys (stents). Form of final device and complexities of an in vivo environment can impact results, so made assumptions whenever possible. Also to identify and test options to slow/or control corrosion rates of mg-based alloys. Currently were modeling different stent designs in COMSOL, and modeling the degradation rate(erosion corrosion) as a function of ion concentration, pH and flow velocity. Our team is having some trouble formulating equations to plug into COMSOL. The question is, does anyone have any suggestions on how I can arrive at a time dependent relationship for erosion corrosion of a metal as a functions of ion concentration, pH and flow velocity? Please feel free to ask any questions.
