Resorbable magnesium alloys are promising materials for osteosynthesis systems. The work describes the influence of the manufacturing process on the degradation of Mg implant systems at different zones. To figure out if the degradation process can be influenced by surface properties, deep-rolling and ball-end milling processes are applied to machine a variety of surface integrity conditions. Corrosion behaviour is analysed by conventional immersion test as well as by drip testing. The latter process is developed in order to acquire timely results, and is based on measuring material loss during corrosion by using a profilometer.
