Abstract
For applications of degradable magnesium implants in medicine the knowledge of the degradation is very necessary. There are many methods to investigate the degradation process. In this study a method especially for small magnesium samples and low degradation rates are evaluated. Therefore seven magnesium alloys were immersed in plasma for 45 days. The magnesium emitted by the sample during degradation process was measured photometrically. These values were compared with the weighted mass loss which is a commonly used method to determine the degradation. The results show that the photometrical measurement of the degradation is an adequate method and allows a time-dependent investigation of degradation.
