An Investigation into the Potential of Turning Induced Deformation Technique for Developing Porous Magnesium and Mg-SiO2 Nanocomposite

A new and novel method of synthesising porous Mg materials has been explored utilising a variant of a processing method previously used for the synthesis of dense Mg materials, namely the turning-induced deformation (TID) method combined with sintering. It was found that the Mg materials synthesised possessed comparable properties to previously-synthesised porous Mg materials in the literature while subsequent sintering resulted in a more consistent mechanical response, with microwave sintering showing the most promise. The materials were also found to possess mechanical response within the range of the human cancellous bone, and when reinforced with biocompatible silica nanoparticles, presented the most optimal combination of mechanical properties for potential use as biodegradable implants due to most similarity with cancellous bone properties.

Automated summary

A new method of synthesising porous Mg materials has been successfully explored by incorporating the turning-induced deformation (TID) method with sintering. The synthesized Mg materials exhibited comparable properties to previously-synthesised porous Mg materials, with subsequent sintering resulting in a more consistent mechanical response, especially with microwave sintering. The materials showed mechanical response within the range of human cancellous bone and, when reinforced with biocompatible silica nanoparticles, presented an optimal combination of mechanical properties for potential use as biodegradable implants due to their similarity to cancellous bone.
