Coating biologically inert metallic implants with biologically active materials, like hydroxyapatite (HA), combines the mechanical benefits of metals with the biocompatibility of HA. Moreover it is an attempt to accelerate bone formation at initial stages of osseointegration, to improve implant fixation and to prevent the release of metal ions from the implant into the body. This book (PhD dissertation) provides information and presents some studies about producing of nano and submicron sized HA powders, densification behavior of produced HA powders, and bioceramics coating on metal...
