In situ modulation of crystallinity and nano-structures to enhance the stability and osseointegration of hydroxyapatite coatings on Ti-6Al-4V implants

Maintaining the high crystallinity and tailoring the nano-structured surface of hydroxyapatite (HA) coatings on Ti-6Al-4V implants play critical roles in realizing their long-term service life span and fast osseointegration for biomedical implants. Herein, a nanorod structured HA (nHA) coating with a pure phase and high crystallinity was successfully developed by combining atmospheric plasma spraying (APS) with hydrothermal treatment (HT). The...
