“…Every time we raise the temperature, we stimulate a greater amount of carbon atoms to migrate to the film, which leads to the observed increase of the zirconium carbide peaks intensities. This is in good agreement with other works, where coatings of transition metal carbides have been successfully manufactured from transition metals thin films deposited on high carbon steel [19][20][21].…”

AbstractZirconium thin films were grown on high carbon steel substrates EN C100 (1 %wt. of carbon) by RF magnetron sputtering. In order to study the reactivity of the film/substrate system as a function of the temperature, one hour vacuum annealing was carried out for different temperatures between 600°C and 1100°C. The films were then analyzed by X-ray diffraction, scanning electron microscopy, glow discharge optical emission spectroscopy (GDOES) and nanoindentation.The obtained results showed a progressive transformation of zirconium film to zirconium carbide.Carbon atoms diffusion from substrate toward the film induced this transformation. The sample annealed at 900°C exhibited the best mechanicals properties (H =17 GPa and E = 220 GPa).Samples treated at higher temperature were affected by oxidation and high microporosity. Even if the conversion is uncomplete, annealing significantly promotes adhesion of the film on the substrate.

“…43 Recently in respect of physiochemical characteristics, as well as morphology, BAG and HA coatings were compared. 114 Surface roughness (Ra = 9.9 0.6 m) was found to be more consistent in BAG coatings than in HA coatings. This may lead to greater levels of osteoblast cell adhesion.…”

“…BAG’s increased solubility levels in comparison to highly crystalline HA can result in an increased rate of osteogenesis throughout the coating . When compared to HA coating, BAG coating with a more homogeneous microarchitecture, improved microhardness, and lower modulus leads to greater adherence and proliferation of MG-63 cells . Moreover, an investigation revealed that the BAG coating of poly( L -lactic acid) (PLLA)-based scaffolding successfully stimulated osteogenesis of ASCs.…”

Baghdadite: A Novel and Promising Calcium Silicate in Regenerative Dentistry and Medicine

et al. 2022

For several years, ceramic biomaterials have been extensively utilized to rebuild and substitute for body tissues. Calcium silicates have been proven to exhibit excellent bioactivity due to apatite formation and cell proliferation stimulation, in addition to degradability at levels adequate for hard tissue formation. These ceramics' excellent biological characteristics have attracted researchers. Baghdadite is a calcium silicate incorporating zirconium ions that enhances human osteoblast multiplication and development, increasing mineralization, and ossification. It has currently received much interest in academic institutions and has been extensively explored in the form of permeable frameworks, varnishes, bone adhesive and gap fillings, microparticles, and nanospheres, particularly in a wide range of biomedical applications. This review article aims to summarize and analyze the most recent research on baghdadite's mechanical characteristics, apatite-forming capability, dissolution pattern, and physiochemical qualities as a scaffold for dentofacial tissuèregeneration purposes.

“…[ 8–10 ] The commonly used metal AM technique is based on arc plasma heat sources such as gas metal arc welding(GMAW) or gas tungsten arc welding(GTAW) and exhibits various advantages, including low manufacturing costs, high productivity, [ 11,12 ] and dissimilar deposition. [ 13–15 ] Moreover, recent advances have substantially supported the use of various wire materials such as aluminum, [ 16–18 ] titanium, [ 19–21 ] and nickel alloys. [ 22–25 ] However, the path generation in the arc‐based metal AM is still based on a point‐by‐point or layer‐by‐layer manufacturing approach.…”

High‐Throughput Metal 3D Printing Pen Enabled by a Continuous Molten Droplet Transfer

et al. 2022

In metal additive manufacturing (AM), arc plasma is attracting attention as an alternative heat source to expensive lasers to enable the use of various metal wire materials with a high deposition efficiency. However, the stepwise material deposition and resulting limited number of degrees of freedom limit their potential for high-throughput and large-scale production for industrial applications. Herein, a high-throughput metal 3D printing pen (M3DPen) strategy is proposed based on an arc plasma heat source by harnessing the surface tension of the molten metal for enabling continuous material deposition without a downward flow by gravity. The proposed approach differs from conventional arc-based metal AM in that it controls the solidification and cooling time between interlayers of a point-by-point deposition path, thereby allowing for continuous metal 3D printing of freestanding and overhanging structures at once. The resulting mechanical properties and unique microstructures by continuous metal deposition that occur due to the difference in the thermal conditions of the molten metal under cooling are also investigated. This technology can be applied to a wide range of alloy systems and industrial manufacturing, thereby providing new possibilities for metal 3D printing.
