Effect of the poly l-lactic acid coating on the corrosion of Magnesium in Hank’s solution

To control the corrosion rate, the Magnesium (Mg) was coated with poly (l-lactic acid) (PLLA) using electrospinning technique. The effectiveness of the PLLA coating on the high purity Magnesium (HP Mg) and alloy AZ91 were tested in Hank’s solution immersion test. The corrosion behaviour of Mg coated...
