چکیده

A nanostructured hydroxyapatite (HA) feedstock was thermally sprayed on Ti–6Al–4V substrates via high velocity oxy-fuel (HVOF process). The particle temperature and velocity for the HA particles in the HVOF jet were monitored during spraying and found to be 1826± 346 ◦C and 638± 82 m/s, respectively. The bioactivity of the coating was investigated in a simulated physiological environment, as an attempt to simulate the real incubation condition of an implant in the human body, via immersing the coating in a simulated body fluid ( e h c K c G s C

Loading Drug on Nanostructured Ti6Al4V-HA for Implant Applications

Arrayed Ti6Al4V nanotubes (TNT) coated with hydroxyapatite (HA) were synthesized via electrochemical anodization method. Paracetamol was loaded onto TNT-HA electrode. Effects of anodization, nanotube formation and hydroxyapatite deposition on sorption and release of the drug were investigated. Saturation time of paracetamol on the anodized samples was 30% shorter than the hydroxyapatite-coated ...

Investigation of oxidation behavior and Thermal spray of mechanically milled CoNiCrAlY–YSZ powders

In this study, the effects of mechanical milling and YSZ reinforcing on oxidation behavior of CoNiCrAlY coatings were investigated. Various amounts of YSZ particles (0%, 5%, 10% and 15 wt.%) were mixed with commercial CoNiCrAlY powder and milled for 24 hrs. Then, the mechanically milled and commercial powders were deposited on Inconel 617 substrate using High Velocity Oxygen-Fuel (HVOF) process...
