“…The coating added a corrosion barrier where its resistance and stability were higher for the OCP coating than those of the HA coating ZM21 Mg alloy spin-coated with four different biodegradable polymers: PLGA, poly(l-lactide acid) (PLLA), poly(3-hydroxybutyrate) (PHB), poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHH) [32] Method: Electrochemical impedance spectroscopy and immersion tests in DMEM supplemented by 10% (v/v) fetal bovine serum (FBS) pre-conditioned at 37 • C up to 28 days. Results: The weight loss (in µg/mm 2 ) decreased from~55 for uncoated sample to~30 for PLGA-coated, and to~15 for other coated samples (PLLA, PHB, PHH)…”

In-Vivo Corrosion Characterization and Assessment of Absorbable Metal Implants

Absorbable metals have been introduced as materials to fabricate temporary medical implants. Iron, magnesium and zinc have been considered as major base elements of such metals. The metallurgical characterization and in-vitro corrosion assessment of these metals have been covered by the new ASTM standards F3160 and F3268. However, the in-vivo corrosion characterization and assessment of absorbable metal implants are not yet well established. The corrosion of metals in the in-vivo environment leads to metal ion release and corrosion product formation that may cause excessive toxicity. The aim of this work is to introduce the techniques to assess absorbable metal implants and their in-vivo corrosion behavior. This contains the existing approaches, e.g., implant retrieval and histological analysis, ultrasonography and radiography, and the new techniques for real-time in-vivo corrosion monitoring.

“…16 Degradable polymers, such as PLLA, PLGA, have good plasticity, mechanical properties, and biocompatibility, which are most commonly used biomaterials for surface modication of alloys to enhance the corrosion resistance of alloys. [17][18][19][20][21] Therefore, PLLA is considered as a coating material to improve the corrosion resistance of magnesium alloy surface in this paper. At present, there are many ways to improve the corrosion resistance of the alloy surface, besides polymer coating, micro-arc oxidation (MAO) process is also one of the surface modication technologies of magnesium alloys.…”

“…Consequently, the CPC film coated on Mg provided an effective protection, which was even continually enhanced with the immersion time. This characteristic of corrosion resistance of the CPC film is really unusual compared to the oxidation films [49], fluoride conversion coatings [50], apatite coatings [51] and polymer coatings [52] on Mg-based materials surfaces. The corrosion resistance of those previously reported films on Mg or Mg alloys was usually high at the initial tests but decreased with immersion time.…”
