Abstract

Procédé de pulvérisation dans un jet de plasma de revêtements biologiquement actifs consistant à produire un jet de plasma turbulent (2), à y introduire des poudres d'oxyde d'aluminium et d'hydroxylapatite d'une granulométrie comprise entre 0,5 et 5 νm et à soumettre l'implant (8) au jet de plasma (2) contenant les particules en poudre. On place l'implant (8) de manière que la distance entre sa surface à revêtir et le point d'introduction de la poudre d'oxyde d'aluminium dans le jet de plasma (2) corresponde au degré de dépôt des particules fusées et accélérées d'oxyde d'aluminium sur la surface de l'implant (8) et de manière qu'elle soit égale, le long du plan croisant le jet de plasma (2) au niveau du point d'introduction dans ce dernier de la poudre d'hydroxylapatite, à 5 à 7 diamètres du jet de plasma turbulent (2) dans ce plan, la poudre d'oxyde d'aluminium étant introduite dans le jet de plasma turbulent (2) pas plus loin de la sortie de la buse (4) du plasmatron, dans le sens d'écoulement du jet de plasma (2), que la poudre d'hydroxylapatite. Le poids de l'hydroxylapatite introduit dépasse celui de l'oxyde d'aluminium.
