Abstract

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.

硼硅纤维增强铝基复合材料用于伤口愈合和骨再生植入物

铝基复合材料是一种新型的复合材料。采用直接金属氧化法(DIMOX)对6xxx铝合金进行氧化，生成氧化铝相本质强化残铝。参数化研究以温度、时间和合金元素为重点进行控制。通过添加不同比例的硼酸(2、5、10和25 wt. %)来确定合金元素的添加。复合材料成分的形状和尺寸的控制是通过700°C的流变铸造建立的。通过对孔隙率的控制，制备了氧化铝、硼硅酸铝本体纤维和微纤维增强泡沫铝。另外，控制硼硅酸铝纳米纤维分散在残铝中，制备铝金属基复合材料涂层。微观结构表征，与能量色散x射线光谱与力学表征一起应用。断裂模量揭示了硼酸的加入对DIMOX和流变铸造的影响。硼硅酸铝涂层被推荐用于伤口愈合和骨再生种植体。
