The advantages of modified air plasma jet method in the process of deposition of hydroxyapatite coatings on the titanium surface

Abstract

The advantages of modified plasma jet construction and its main characteristics were investigated in the process of the hydroxyapatite (CHA) deposition on the surface of titanium substrate. Calculation of the CHA particles velocity and residence time inside of plasma torch PJ-100 were made. The depth of CHA coating, its morphology and its bond with the titanium substrate were investigated. Special care was paid to the extraordinary coating adhesion properties. All the obtained results showed that this plasma jet installation and process of deposition are very promising for obtaining satisfying coatings on the implants for hips, knees and teeth.
