TLDR
Calcium phosphate coatings produced using the ion beam sputter deposition process are amorphous and a series of different post-deposition heat treatments were conducted to produce crystalline HA-type coatings, suggesting the formation of a new phase.About:

Material fundamentals and clinical performance of plasma-sprayed hydroxyapatite coatings: A review
TL;DR: A reflection on the results indicates that HA coatings can promote earlier and stronger fixation but exhibit a durability that can be related to the coating quality.
Journal ArticleDOI
A review on calcium phosphate coatings produced using a sputtering process--an alternative to plasma spraying.
TL;DR: This review will discuss the characterization of sputtered CaP coatings before and after post-deposition treatments and tissue responses to some of the characterized coating surfaces.

Plasma sprayed hydroxyapatite coatings on titanium substrates Part 1: Mechanical properties and residual stress levels
Y.C. Tsui,C. Doyle,T.W. Clyne +2 more
TL;DR: Hydroxyapatite (HA) coatings have been sprayed on to substrates of Ti-6Al-4V, using a range of input power levels and plasma gas mixtures, and the phase constitution, porosity, degree of crystallinity, OH ion content, microstructure and surface roughness of the HA coatings were made.

Apatite Crystallites: Effects of Carbonate on Morphology
TL;DR: The interference of carbonate with the good crystallization of apatite, and its weakening effect on the bonds in the structure, increase the dissolution rate and the solubility, thereby presumably contributing to the susceptibility to caries of dental apatites containing carbonate.
