“…There are numerous materials that can be used as placeholders. Researchers employed ammonium bicarbonate [14], urea [15], sodium chloride [16], polymer granules [17], and magnesium as placeholders [18]. The material that can be utilized as a space holder should have certain features, such as no reactivity with the matrix powder, little or no residue after removal, ease of processing, and so on.…”

The greatest challenge in making biocompatible metals implantable is anticipating the push protecting impact, which suggests that the metal and bone cells will not bond as well as they ought to. In any case, there are ways to overcome this problem. One way is to form the metal hardened, repressing the stress-shielding impact. Another way is to use porous materials, allowing the metal and the cells to bond better. Titanium powder is used to make titanium foam structures, which can help to stop bone growth and improve the attachment of dental implants. These applications involve load bearing in the aerospace and ship manufacturing industries in addition to trabecular implants in the biomedical industry which is the focus in this paper where biocompatibility and mechanical properties of titanium are extremely critical. Although implants are extremely rigid in comparison to the host bone, they still need to be designed meticulously to avoid stress-shearing or overloading the connected bone and promote bone regeneration. Additionally, several coating and roughening processes are applied toward enhance foam and bone attachment to the implant surface. This research intends to bring attention to the significance of porosity in the Titanium foam dental implant fusion with bone tissue, as well as the many production methods that are presently under investigation. For the best possible biological characteristics in Titanium foam, it has been shown that the preservative built-up approach is effective in controlling both the pore size and shape.

“…Table 2 shows the mechanical properties of various metal foams with varying porosities and strain rates. The plateau stress has been found to have higher values at porosity varying from 60 to 70%, while energy absorption capacities are higher for higher porosity values [ 59 , 60 , 61 , 62 ]. The effect of pore morphology on the compressive strength of Al foam concluded that the pore shapes of foams had a greater influence on their mechanical properties than the pore size [ 63 ].…”

Metal foams possess remarkable properties, such as lightweight, high compressive strength, lower specific weight, high stiffness, and high energy absorption. These properties make them highly desirable for many engineering applications, including lightweight materials, energy-absorption devices for aerospace and automotive industries, etc. For such potential applications, it is essential to understand the mechanical behaviour of these foams. Producing metal foams is a highly challenging task due to the coexistence of solid, liquid, and gaseous phases at different temperatures. Although numerous techniques are available for producing metal foams, fabricating foamed metal still suffers from imperfections and inconsistencies. Thus, a good understanding of various processing techniques and properties of the resulting foams is essential to improve the foam quality. This review discussed the types of metal foams available in the market and their properties, providing an overview of the production techniques involved and the contribution of metal foams to various applications. This review also discussed the challenges in foam fabrications and proposed several solutions to address these problems.

“…From the literature survey, it can be summarized that a few studies [17,19,20] have used aluminum, zinc, magnesium and copper metals as foams, while some other studies [14,15,21] have used nickel alloys, aluminum alloys and titanium-based copper alloys as foams. In a few works [7,8,10], melt foaming, direct foaming with a blowing agent, and investment casting were used to fabricate metal or alloy foams.…”

Metal foams and alloy foams are a novel class of engineering materials and have numerous applications because of their properties such as high energy absorption, light weight and high compressive strength. In the present study, the methodology adopted to develop a Ni-Cr alloy foam is discussed. Polyurethane (PU) foam of 40PPI (parts per inch) pore density was used as the precursor and coating techniques such as electroless nickel plating (ELN), ultrasonic-assisted electroplating of nickel (UAEPN), and pack cementation or chromizing were used to develop the Ni-Cr alloy foam. The surface morphology, strut thickness and minimum weight gain after each coating stage were evaluated. It was observed from the results that the adopted coating techniques did not damage the original ligament cross-section of the PU precursor. The minimum weight gain and the coating thickness after the UAEPN process were observed to be 42 g and 40–60 μm, respectively. The properties such as porosity percentage, permeability and compressive strength were evaluated. Finally, the pressure drop through the developed foam was estimated and verified to determine whether the developed foam can be used for filtering applications.
