Abstract Scope |
Adapted corrosion rates are necessary for a time-defined dissolving of absorbable implants such as ZnMg alloys. For triggering the corrosion rate, a combination with a polymer seems suitable.
Therefore, a leaching technology and chemical treatment had been developed for Zn1.5Mg and PLA to fix the polymer proper onto the surface of the metal, outside and inside. Besides developing the chemical conditions for a good bond between the two materials, the challenge is to produce pores as big as necessary to infiltrate the metal by the polymer but also as small as possible to avoid too strong weakening of the leached, open structured metal. Moreover, depending on the volume of the pores, forming processes are necessary to adapt the parts to their needs. The technology is introduced as well as boundary conditions for filling the inside of the metal. |
