Advanced biodegradable Mg/Mg alloys implants with corrosion protection and antimicrobial shielding by hybrid coatings

project no.  PN-II-RU-TE-2014-4-0396

             The production of biodegradable Mg-based metal implants is a challenging topic. There are still several involved processes that are not fully understood. The investigation of these phenomena will enable the development of a new generation of biomedical implants. One of the most effective ways to protect metal implants from corrosive media is to coat the base materials with innovative bioactive biomaterials which are expected to promote synergic interactions between implant and tissue. The innovative solution proposed in this project is to obtain by pulsed laser technologies, thin coatings with different characteristics. Our approach will permit a shortening of patients healing time and provide a solution for the long-term modification of biodegradable metallic implant-like surfaces.

1. Development of advanced pulsed laser technologies suitable for thin films deposition;

2. Selecting the optimal composition with highest corrosive action and efficiency antimicrobial activity.  
3. Further research on MAPLE depositions on the selected compositions in objective 2.
4. Development of technologies for anticorrosive and antimicrobial coatings on large surfaces to be used on Mg/Mg alloys MIs.

Expected Results :

1.Development of a new generation of biodegradable MIs based on Mg/Mg alloys which is expected not to be unaffected by dysfunctions encountered in the research reported in recent studies.
