Structure and Properties of Modified Plasma-Sprayed Composite Coatings on a Titanium Base

  • Published:
Mechanics of Composite Materials Aims and scope

The structure and properties of hydroxyapatite (HA) plasma-sprayed coatings modified by Al2O3 and AlOOH nanoparticles have been investigated using different methods. It is found that the impregnation of HA particles before forming the coating ensures their most uniform distribution in the coating and increases its adhesion to 17.6 MPa. Agglomeration and milling of the powder mixture before spraying contribute to the formation of a uniform porous structure of the coating and a developed surface morphology with an increased adhesion from 10.4 to 17.8 MPa.
