To this end, micro-computed tomography and scanning electron microscopy with energy-dispersive X-ray spectroscopy were used, followed by a tree regression analysis. A non-linear relationship was found between degradation rate and the precipitation of calcium salts. The mean absolute error for predicting the degradation rate was 1.35 mm/yr. This comparatively high value indicates that ionic interactions were exceedingly complex or that an unknown parameter determining the degradation may exist.en0010-938XCorrosion science2021Elsevier Sciencehttps://creativecommons.org/licenses/by/4.0/Magnesium degradationMicroCTSimulated body fluidTree regressionMLE@TUHHTechnikExploring key ionic interactions for magnesium degradation in simulated body fluid – a data-driven approachJournal Article10.15480/882.348610.1016/j.corsci.2021.10927210.15480/882.348610.15480/336.2862Journal Article
