Stability of hydroxyapatite coating of different crystallinities on a titanium alloy implant material after cyclic fatigue
Autor: P.N. Hale, D.P. Mukherjee, S.A. Napper, S. Ashroff, U. Siriwardane
Publikováno v: Proceedings of the 1996 Fifteenth Southern Biomedical Engineering Conference.
Plasma-sprayed hydroxyapatite (HA) coatings of three different crystallinities on titanium alloy (Ti-6Al-1V) substrate were analyzed for fatigue-induced changes in their stability. The HA starting powder and the coatings were characterized using X-ra

Cyclic fatigue of hydroxyapatite-coated titanium alloy implant material--effect of crystallinity
Autor: S, Ashroff, S A, Napper, P N, Hale, U, Siriwardane, D P, Mukherjee
Publikováno v: Journal of long-term effects of medical implants. 6(3-4)
Titanium alloy (ASTM F-136) rods were coated with hydroxyapatite (HA) of 3 levels of crystallinity, which were determined by X-ray diffraction (XRD) analysis to be 60.5%, 52.8%, and 47.8%. Fourier Transform Infrared (FTIR) spectroscopy analysis showe
