Mechanical and corrosion behaviour of hydroxyapatite reinforced Mg-Sn alloy composite by squeeze casting for biomedical applications

Effect of Hydroxyapatite on the Mechanical Properties and Corrosion Behavior of Mg-Zn-Y Alloy

Mg-Zn-Y alloys with a long period stacking ordered (LPSO) phase are potential candidates for biodegradable implants; however, an unfavorable degradation rate has limited their applications. Hydroxyapatite (HA) has been shown to enhance the corrosion resistance of Mg alloys. In this study, Mg97Zn₁Y₂-0.5 wt% HA composite was synthesized and solution treated at 500 °C for 10 h. The corrosion behav...

Synthesis of Peculiar Structure of Hydroxyapatite Nanorods by Hydrothermal Condition for Biomedical Applications

      In the present work, the effect of Ca(NO3)2.4H2O and (NH4)2HPO4 primary solutions as the beginning materials in synthesis of a calcium phosphate phase, was examined. So, we investigated the wet chemical reactions in solution at different temperatures by a hydrothermal condition aimed at hydroxyapatite (Ca10(PO<su...

Mechanical properties of hydroxyapatite whisker reinforced polyetherketoneketone composite scaffolds.

The apparent mechanical properties of hydroxyapatite (HA) whisker reinforced polyetherketoneketone (PEKK) scaffolds were evaluated in unconfined, uniaxial compression to investigate the effects of the porosity (75%, 82.5% and 90%), HA content (0, 20 and 40 vol%) and mold temperature (350, 365 and 375 ( composite function)C). Increased porosity resulted in a non-linear decrease in the elastic mo...

Fabrication of TiC particulate reinforced Ni-50Fe super alloy matrix composite powder by mechanical alloying

Mechanical alloying is a powder metallurgy processing technique involving cold welding, fracturing, and rewelding of powder particles in a high-energy ball mill. In this work, NiFe-TiC composite powders were prepared by mechanical alloying process using planetary high-energy ball mill. The effect of TiC addition by weight percent on the NiFe solid solution formation, grain size, lattice paramet...
