![عکس صفحه اول مقاله: Microstructural study of a titanium-based biocomposite produced by the powder metallurgy process with TiH2 and nanometric β-TCP powders Microstructural study of a titanium-based biocomposite produced by the powder metallurgy process with TiH2 and nanometric β-TCP powders](/preview/png/1429659.png)
A titanium-based composite with Ca-P phases was prepared in situ by powder metallurgy processing with TiH2 and nanometric β-TCP powders. Crystal phases of the as-fabricated composite are found to be α-Ti, CaTiO3 and TixPy phase(s). The TixPy and CaTiO3 phases resulted from the reaction between titanium and β-TCP at about 1135 °C. The composite presented a mean compressive strength of 635 MPa and a lower contact angle than pure titanium.
► TiH2/10% β-TCP composite was prepared by powder metallurgy in vacuum.
► The starting powders were mixed uniformly by friction milling.
► The decomposition of β-TCP took place at about 1135 °C.
► Ti, CaTiO3 and TixPy phases were found in the composite.
► The composite is not ductile and presented a lower contact angle than pure titanium.
