Biodegradable Metals
Supervisor: myself :)
Over the last years, biodegradable metals on magnesium and iron basis advanced into various clinical applications in different markets. The theoretical models on clinical performance derived from preclinical experiments seem to be confirmed by clinical reports. Also, aspects of safety are confirmed by clinical reports, which will be presented and discussed in detail. Additionally, promising research on zinc-based products will be presented and even molybdenum is critically considered as a biodegradable metal. Especially additive manufacturing has become an increasing topic for production of biodegradable metals and a short summary will be presented. Moreover, an inherent part of biodegradable metals performance seems to be its surface modification and coating to control the corrosion process. Over the years, various surface modification techniques have been proposed to improve the corrosion resistance and surface properties of Mg and other degradable alloys. Low pressure plasma contains highly energetic and reactive species able to induce the required physiochemical surface changes. For example, magnetron sputtering was used to improve consistently the radiopacity of tiny Fe-Mn-C-based alloys, mainly by including W in the outermost layers, without affecting its structural properties. Overall, results from physical vapour deposition, plasma–enhanced chemical vapour deposition, plasma immersion ion implantation are topics to be discussed.
