摘要：

Pulsed laser deposition was used to deposit thin films of calcium hydroxylapatite (Ca10(PO4)6(OH)2), or HA, on polished substrates of Ti-6Al-4V. Thin films of pure, crystalline HA, uncontaminated by other calcium phosphate phases, were deposited over a range of temperatures between 400 and 800-degrees-C. The HA films were polycrystalline with a preferred (001) crystallographic orientation, as determined by transmission electron microscopy and x-ray diffraction. Adhesion of the HA films to the Ti-6Al-4V substrates was excellent when films were deposited at temperatures less-than-or-equal-to 600-degrees-C; in a scratch test, mean pressures of ca. 10(10) Nm-2 produced conformational cracking in a film deposited at 600-degrees-C, but no decohesion from the substrates.
