“…Solid state processing methods involve the use of metal powders and are especially preferred when the alloy of the foam (e.g., Ni) to be produced has a high melting temperature [1]. Among the solid state processing methods, the slurry coating technique can produce open-cell metal foams with the lowest relative densities [2][3][4][5][6]. In this method, an open-cell polymeric sacrificial template is first coated with the metal slurry.…”

“…It was found that the viscosity of metal powder slurries (e.g., pure titanium [2], Ti6Al-4V [8] and aluminium [9]) increases with powder concentration. However, the effect of slurry composition on the resulting foam properties remains largely unknown.…”

“…Note that the fine metal powders are suggested for the slurry because the use of metal powder particles exceeding 25 µm for the slurry often results in structural defects and voids deep within larger foam pieces [5]. Open-cell foams of stainless steel [5], carbonyl iron [5], Fe-Cr-Al [5,10], aluminium [9], titanium [2], Ti-6Al-4V [5,8,11] and molybdenum [5] have been successfully fabricated using the slurry coating method. However, the production of foams for applications involving exposure to high temperature environments requires that superalloys be used as foam materials.…”

Open-cell nickel-based alloy foams are attractive materials for applications such as sound damping and heat exchange, especially those involving exposure to high temperature environments. This study demonstrated the potential of a developed slurry coating technique for manufacturing open-cell Inconel alloy foams, and then investigated the effect of slurry composition on the microstructure and mechanical properties of the foams. It was found that the compressive properties of the foam can be quantitatively related to its relative density using the empirical equations. The deformation behaviour of the foam is bending-dominated; and unit cell struts undergo brittle fracture after the elastic region. Increasing the slurry solid loading leads to a higher average bulk foam density and more non-uniform crush bands in the foam under compression. Compared to other fabrication processes, this slurry coating technique is able to to produce open-cell Inconel foams with relatively higher strength-to-weight ratios. This study also revealed that the sound absorption capability of the foam increases when its unit cell size is reduced.

[**] One of the authours (MMS) would like to acknowledge a studentship from the Iraqi Ministry of Higher Education and Scientific Research.Among the porous metals, those made of titanium attract particular attention due to the interesting properties of this element. This review examines the state of research understanding and technological development of these materials, in terms of processing capability, resultant structure and properties and the most advanced applications under development. The impact of the rise of additive manufacturing techniques on these materials is discussed, along with the likely future directions required for these materials to find practical applications on a large scale.

Scaffolds having appropriate mechanical strength and providing a proper microenvironment for osteogenesis are expected to be effective alternatives to autografts for bone regeneration. In this study, ant‐nest type porous (ANP) scaffolds consisting of CO3Ap were fabricated using calcium carbonate powder or slurry and two types of polyurethane foam through a dissolution–precipitation reaction. ANP‐type, three‐dimensional, interconnected porous CO3Ap scaffolds were fabricated by burning out the struts of polyurethane foams embedded in CaCO3, followed by compositional transformation from CaCO3 to CO3Ap. The types of polyurethane foam and impregnation methods of CaCO3 into polyurethane form affected the geometry of the resulting ANP structures. Mechanical and in vivo biological performances of these scaffolds relied on the geometry of the ANP structures. The ANP structures displayed had a clear structural advantage in bone regeneration, owing to the promotion of cell and tissue migration throughout the scaffolds. In particular, ANP‐structured scaffolds, which had highest porosity, interconnectivity, and smallest strut thickness, had a mechanical strength comparable to cancellous bone, formed more new bone, were highly resorbed, resulting in cancellous bone‐like bone tissue regeneration at 12 weeks of healing. The results suggest that bone regeneration after the migration of cell and tissue into the entire scaffolds is affected by strut thickness preferentially over porosity and interconnectivity. ANP‐structured CO3Ap scaffolds are attractive for bone regeneration.
