[Rotational bending test of hydroxylapatite plasma-coated models of TiAl6V4].
Plasma spraying of hydroxyapatite coatings onto hip joint and knee endoprosthesis implants and dental implants is state of the art. Nevertheless, there is still a lack of data on the long-term behavior of such coatings. Using the rotating-bending test DIN 50,113 it is shown that parts plasma-sprayed with 200 microns OSPROVIT exhibit delamination only after fracture of the metallic component. At a load of 400 MPa more than 1.10(9) loading cycles were achieved.
