“…The tool is displaced upwards by a predetermined level to deposit a subsequent layer leading to fabrication of 3D geometries. This technique is similar to friction surfacing in which a consumable feed rod is used instead of hollow tool which gets deposited as a layer [111,112]. There is a possibility of [37] composite fabrication through usage of hollow rods filled with ceramic powder as a feed-stock [113].…”

Magnesium based alloys are attractive materials for biomedical applications as a result of their similar properties to the human bone and vital nature of the Mg ions during various functions of the human body. However, these materials suffer from poor corrosion resistance in chloride containing physiological environments. As a result, surface modification of biomedical alloys is needed to not only enhance the corrosion resistance but also biointegration characteristics. The current review article mainly focuses on beam and friction stir based techniques for surface processing of biomedical Mg alloys and composites. Each technique is further divided into sub-methods. Under the beam based processing, surface melting and bioceramic coating synthesis are discussed in detail. In the case of friction based methods, friction stir processing for grain refinement and techniques of surface modification to produce surface bioceramic composites are discussed. Furthermore, latest developments in the area of beam as well as friction stir additive manufacturing of biomedical Mg alloys and composites are elucidated. Lastly, possible directions for future progress and scaling up the lab level developments to actual applications in these materials processing areas for biomedical Mg alloys are provided.

“…1. Schematic diagram of friction surfacing process [3] Kumar et al [4] examined the effect of axial force, spindle speed and table speed on bonding strength and bend ductility for the deposition of AA6063 on the mild steel surface. The authors concluded that 1.25-1.3 mm deposition thickness provides maximum strength and ductility.…”

Surface roughness plays an essential role in friction surfacing deposition as a smooth substrate surface polishes both consumable and substrate tools, resulting in a lack of deposition. Hence, an attempt is made to investigate the effect of substrate surface roughness while friction surfacing of AA6061-T6 coating on CR01 low carbon steel and its performance is compared through push-off strength. It is revealed that with an increase in substrate surface roughness, more rubbing action occurs between consumable tool and substrate, which results in higher heat generation and reduction in deposition thickness. The grain refinement is observed at the coating region due to dynamic recrystallisation, which results in fine grain microstructure. The substrate with Ra roughness values 1.5-2.5, 5.5-6.5 and 7.5-8.5 µm showed 26, 32 and 45 MPa push-off strength, respectively. Hence, it is inferred that the push-off strength increases substantially with an increase in the substrate surface roughness.

“…Similar to FSW, additive friction stir deposition (AFSD) is a thermo-mechanical process derived from FSW, friction surfacing (FS) [13][14][15][16][17], and the friction stir forming technique [18]. The AFSD process utilizes frictional heat generated by a rotating tool and severe plastic deformation physics to plastically deform the material, inducing material flow to form a layer-by-layer AM process [19][20][21].…”

In this research, we explore the preliminary effects of processing conditions using a novel additive manufacturing (AM) process, known as additive friction stir deposition (AFSD), on resulting build direction (BD) mechanical performance. Using the AFSD process, a feasibility study of three AM builds of identical size are created using differentiating processing parameters. A relationship referred to as the deposition pitch, exhibiting similarities to weld pitch, is determined to be a simple but effective predictor of the interlayer bonding in AFSD processing of AA7020. The deposition pitch directly correlates the necessary temperature, time, and pressure required for effective solid-state bonding. Using this correlation, increased mechanical performance in the BD is achieved through an increase in deposition pitch. A reduction in the deposition pitch from 4.46 rev/mm to 1.08 rev/mm resulted in a significant decrease in failure strain from 24.4% to 0.82%, with the failure mechanism shifting from a ductile failure to brittle failure. The inverse relationship between grain refinement and BD failure strain at high deposition pitches suggests deposition pitch and heat input are the dominant factors in the resulting BD mechanical properties.
