Calcium phosphate coatings ( 50 mm thick), especially those made with hyd- xyapatite (HA), produced by the plasma-spraying process have been succe- fully used on orthopedic and dental implants to improve fixation of these implants in bone. Thin calcium phosphate coatings ( 10mm thick) formed by various techniques other than plasma spraying may be the successor of the current thick plasma-sprayed coatings because of their improved properties. Like plasma-sprayed HA coatings, these alternative calcium phosphate thin coatings are capable of enabling bone formation on their surfaces and forming a...
