Developing hydroxyapatite CAPS coatings on metallic implants for tissue replacement

Developing hydroxyapatite CAPS coatings on metallic implants for tissue replacement

Hydroxyapatite (HA) is an appropriate ceramic for artificial teeth or bones due to its excellent biocompatibility and bioactivity. Unfortunately, the mechanical properties of pure HA ceramics are poor and these make them unsuitable as high load-bearing implants. A solution to this problem is the use...
