Abstract Scope Resorbable magnesium alloys are promising materials for osteosynthesis systems. This work describes the influence of manufacturing on the degradation process of Mg implants. To prove the assumption that the degradation process can be controlled by surface properties, deep-rolling and ball-end milling processes were applied to machine a variety of surface integrity conditions. To analyse the corrosion behaviour a conventional immersion test as well as drip test is used. The latter process was developed in order to acquire more timely results, and is based on measuring material loss during corrosion by use of a profilometer. It is observed that deep-rolling with 200 bar and an overlap of 75 % is an effective process to protect the surface from the simulated body fluid attack.
