In this paper, three goals are attacked, namely synthesis of nanostructured hydroxyapatite (HA) powder, obtaining HA phase constitution close to that of the bone hydroxyapatite, and preserving the initial HA composition and crystal structure in the sprayed coating. HA-aluminum composite coatings are produced using the cold gas dynamic spray method (CGDS). It is observed that the CGDS process enables the application of coatings without changing the phase composition of the HA, whereby the HA biocompatibility is retained. Paper includes a German-language abstract.
