FUMERO PEREZ, Abel et al. A preliminary study about HAP-200 hydroxyapatite coatings obtained by atmospheric plasma. Rev Cubana Invest Bioméd [online]. 2011, vol.30, n.2, pp.280-291. ISSN 0864-0300.

Hydroxyapatite is classified as a bioactive material whose ability of interaction with bone allowed its use in a satisfactory way for orthopedic and dental application. In present paper the hydroxyapatite produced by the National Center of Scientific Researches, was projected by means of an atmospheric plasma torch on an austenitic stainless steel substrate. The particles' size was determined by laser dispersion and the projection distance fluctuates between 20 and 60 mm. The microstructure and the powder phase composition, as well as the coating achieved were examined by optical microscopy, scanning electron microscopy and X-rays diffraction (XRD). The coating's point chemical composition was analyzed by energy-dispersion spectrometry (EDS) and the hardness, layer thickness and crystallization were measured. Results showed that crystallization decreases according to the increase of projection distance, but not its hardness and layer thickness.

Keywords : Projection distance; hydroxyapatite; microstructure; thermal plasma.
