TI  - Crystallographic characteristics of plasma-sprayed calcium phosphate coatings on 
      Ti-6Al-4V.
PG  - 661-72
AB  - The purpose of this study was to investigate the crystallographic characteristics 
      of 3 sets of plasma-sprayed hydroxyapatite (HA) coatings prepared with different 
      degrees of crystallinity on Ti-6Al-4V substrates. X-ray diffraction analyses were 
      performed on the coatings to determine mean percent crystallinity, calcium 
      phosphate phases present, average crystallite size, and residual strain. The mean 
      percent crystallinity for the 3 sets of coatings ranged from 49 to 60%. The 
      coatings that achieved the highest crystallinity consisted almost entirely of HA. 
      As the coating crystallinity decreased, increasing amounts of alpha- and 
      beta-tricalcium phosphate and tetracalcium phosphate were detected. The mean HA 
      crystallite size for the 3 sets of coatings ranged from 0.02 to 0.05 micron. 
      Differences in mean interplanar spacing for selected crystallographic planes of 
      HA, compared with the pure ICDD (International Center for Diffraction Data) 
      powder standards, implied that the coatings were in an uneven state of tensile 
      strain.
