Abstract:
Metallic implants are the most commonly used implants in biomedical applications. Calcium
phosphate bioceramics, especially hydroxyapatite (HA) coatings are used to improve the
osseiointegration and bonding between the implant and the bone interface. A number of techniques
have been suggested in literature to develop implant coatings. The thermal spray methods such as
plasma spray and high velocity oxy-fuel spray coating techniques shows great potential for biomedical
applications. The focus of present paper is to describe the thermal spray techniques for coating metallic
implants, highlighting various issues related to thermally sprayed HA coatings on metallic implants
with the help of existing literature.
