Abstract
The present invention relates to a process for making bioactive coatings on osseous prostheses, wherein a mist of particles containing calcium ions and orthophosphate ions is made from solutions and said mist is brought into contact with a substrate (notably an implant) made of inert material under such operational conditions that a hydroxyapatite coating is formed by reaction on the hot surface of said inert substrate, said process being characterized by the fact that the operating conditions to make the deposit are selected so that a liquid film forms on the hot surface of said substrate during the deposition.
