Ti–Al–Co (6 wt% of Al and varying amount of Co content) alloys foams of different space holder contents (40 ± 2.5 to 70 ± 5% by volume with an increment of 10%) were fabricated using ammonium bicarbonate (NH₄HCO₃) as space holder. These foams were analysed in terms of cell morphology, microstructure, mechanical and corrosion properties. The cell sizes were almost invariant to the Co content and space holder content. The cell wall thickness increased with increase in relative density. It was found that with increase in Co contents in the Ti–Al–Co alloys, compressive strength, Young's modulus, energy absorption capacity and microhardness increases. Empirical relations were established to correlate these mechanical properties with Co wt%, strain rate (έ) and relative density. The experimentally obtained results were also verified with the existing analytical relation. It was observed that the openness of the foams increases with increase in space holder content. It was found that the Co concentration in the samples does not influence degree of openness but it influences the corrosion behaviour of the investigated foams. The corrosion rate (in mmpy) and electrochemical potential parameters were also obtained in simulated bio fluid, and compared with those of other Ti-alloys and found to be in close agreement with each other.To examine the suitability for bone implant application, the investigated Ti–Al–Co alloys foams were compared with human cortical as well as cancelleous bone in terms of macrostructural, microstructural, corrosion behaviour and mechanical properties. In every aspects these foams were found to be suited for bone implant application.

使用碳酸氢铵（NH）制造了不同占位符含量（体积分数为40±2.5至70±5％，增量为10％）的Ti–Al–Co（Al的6 wt％和不同的Co含量）合金泡沫₄ HCO ₃）作为空格。从泡孔形态，微观结构，机械和腐蚀性能方面对这些泡沫进行了分析。像元大小几乎不变于Co含量和空间保持剂含量。细胞壁厚度随相对密度的增加而增加。研究发现，随着Ti-Al-Co合金中Co含量的增加，抗压强度，杨氏模量，能量吸收能力和显微硬度也随之增加。建立了经验关系，以将这些机械性能与Co重量％，应变率（έ）和相对密度相关联。实验获得的结果也用现有的分析关系进行了验证。观察到，泡沫的开放度随着空间容纳物含量的增加而增加。发现样品中的Co浓度不影响开孔度，但是影响所研究的泡沫的腐蚀行为。还获得了在模拟生物流体中的腐蚀速率（单位：mmpy）和电化学势参数，并与其他钛合金进行了比较，发现它们之间具有密切的一致性。在宏观结构，微观结构，腐蚀行为和机械性能方面，将Ti-Al-Co合金泡沫与人的皮质以及松质骨进行了比较。在各个方面，发现这些泡沫适用于骨植入物的应用。在模拟的生物流体中还获得了腐蚀速率（单位为mmpy）和电化学势参数，并与其他钛合金进行了比较，发现它们之间具有密切的一致性。在宏观结构，微观结构，腐蚀行为和机械性能方面，将Ti-Al-Co合金泡沫与人的皮质以及松质骨进行了比较。在各个方面，发现这些泡沫适用于骨植入物的应用。在模拟的生物流体中还获得了腐蚀速率（单位为mmpy）和电化学势参数，并与其他钛合金进行了比较，发现它们之间具有密切的一致性。在宏观结构，微观结构，腐蚀行为和机械性能方面，将Ti-Al-Co合金泡沫与人的皮质以及松质骨进行了比较。在各个方面，发现这些泡沫适用于骨植入物的应用。腐蚀行为和机械性能。在各个方面，发现这些泡沫适用于骨植入物的应用。腐蚀行为和机械性能。在各个方面，发现这些泡沫适用于骨植入物的应用。
