Characterization of sputtering HA coating using powder and sintered HA targets

Synthesis and Structural Properties Characterization of HA/Alumina and HA/MgO Nanocomposite for Biomedical Applications

HAAlumina nanocomposite is biocompatible and has desirable mechanical and physical properties. Less cost, simple synthesis method, and fast production are the added advantages of this nanocomposite. Thus HA coatings on the surface of alumina substrates are used to combine excellent bioactivity of HA with superior mechanical properties of the alumina substrates. One of the elements associated wi...

Effect of Water-Glass Coating on HA and HA-TCP Samples for MSCs Adhesion, Proliferation, and Differentiation

Ca-P and silicon based materials have become very popular as bone tissue engineering materials. In this study, water-glass (also known as sodium silicate glass) was coated on sintered hydroxyapatite (HA) and HA-TCP (TCP stands for tricalcium phosphate) samples and subsequently heat-treated at 600°C for 2 hrs. X-rays diffraction showed the presence of β- and α-TCP phases along with HA in the HA-...

Hydroxylapatite (HA) Powder for Autovaccination Against Canine Non Hodgkin’s Lymphoma

Characterization of New PEEK/HA Composites with 3D HA Network Fabricated by Extrusion Freeforming.

Addition of bioactive materials such as calcium phosphates or Bioglass, and incorporation of porosity into polyetheretherketone (PEEK) has been identified as an effective approach to improve bone-implant interfaces and osseointegration of PEEK-based devices. In this paper, a novel production technique based on the extrusion freeforming method is proposed that yields a bioactive PEEK/hydroxyapat...

Effect of Alkali and Heat Treatment on Biomimetic HA Coating on Ti6Al4V

In this study, time of calcium phosphate formation on Ti6Al4V alloy with or without alkali and heat treatments was investigated. Specimens were soaked in 0, 5, 10 M solutions of NaOH at temperatures of 60 or 80 °C for 24, 72 h. Their surfaces were characterized using scanning electron microscopy and thin film X-ray diffraction. It was found that optimum condition is 72h soaking in 5 M NaOH in 8...
