Borosilicate fiber reinforced aluminum matrix composite for wound healing and bone regeneration implants

Aluminum metal matrix composite is produced via new emerging processing. Direct metal oxidation, DIMOX, is applied on aluminum alloy 6xxx to produce alumina phase intrinsically reinforce residual aluminum. Parametric study focused on temperature, time and alloying elements are controlled. Alloying elements addition established by the addition of boric acid at different percentage 2, 5, 10 and 25 wt. %. The control of shape and size of composite constituents is established via rheocasting at 700°C. The control of porosity produced Aluminum foam reinforced with alumina and aluminum borosilicate bulk fiber and micro fibers. In addition, Aluminum borosilicate Nano fibers dispersed in residual aluminum is controlled to produce coating on aluminum metal matrix composite. Microstructural characterization, with energy dispersive X-ray spectroscopy is applied along with mechanical characterization. Modulus of rupture reveals the effect of addition of boric acid in DIMOX and rheocasting. The application of aluminum borosilicate coating is recommended for wound healing and bone regeneration implants.
