Examining the HAP+ Fe2O3 Response in the Magnetic Field, Radiation Protection and Mechanical Properties

Abstract

HAP (Hydroxyapatite) bio-composite has been used extensively to repair and replace bone and teeth tissues in the human body. However, because of the poor mechanical features of HAP bio-composites, significant enhancements in the strength and toughness of pure HAP have been achieved by the insertion of various alloys and materials into HAP. Accordingly, the present study evaluates the radiation shielding and mechanical features of the Fe2O3 -reinforced HAP composite as an implant for 0.0, 2.5, 5.0, and 7.5 wt.% Fe2O3. Also, the composite response in a magnetic field has been investigated. Employing FLUKA Monte Carlo Code, radiation shielding factors are obtained. In addition, the mechanical characteristics of the studied composites are evaluated using the theoretical method. Findings reveal that increasing the Fe2O3 contents in HAP bio-composite enhances the preferred samples’ radiation shielding and mechanical qualities. Furthermore, in the absence of a magnetic field, the particles' spatial map exhibits symmetric behavior along the x-axis, however, a different trend is observed in the presence of a magnetic field with a value of Bx=5 microT.
