Structure and Mechanical Properties of Three-Dimensional Capillary-Porous Titanium Coatings on Intraosteal Implants

摘要

We developed a process of plasma wire spraying of three-dimensional capillary porous titanium coatings for intraosteal implants with the use of two additional arc discharges between the plasma gun and the wire and between the plasma gun and the substrate. By raising the temperature of sprayed particles and activating the substrate, we enhanced the shear strength up to 120 MPa for a titanium coating having the porosity of 46%.
