The objective of this experimental work was to examine and characterise the route for obtaining demonstrative temporary biodegradable personalised implants from the Mg alloy Mg-10Zn-0.5Zr-0.8Ca (wt.%). This studied Mg alloy was obtained in its powder state using the mechanical alloying method, with shape and size characteristics suitable for ensuing 3D additive manufacturing using the SLM (selective laser melting) procedure. The SLM procedure was applied to various processing parameters. All obtained samples were characterised microstructurally (using XRD—X-ray diffraction, and SEM—scanning electron microscopy); mechanically, by applying a compression test; and, finally, from a corrosion resistance viewpoint. Using the optimal test processing parameters, a few demonstrative temporary implants of small dimensions were made via the SLM method. Our conclusion is that mechanical alloying combined with SLM processing has good potential to manage 3D additive manufacturing for personalised temporary biodegradable implants of magnesium alloys. The compression tests show results closer to those of human bones compared to other potential metallic alloys. The applied corrosion test shows result comparable with that of the commercial magnesium alloy ZK60.

“…Previous studies have revealed that the nanoscale modified layer differs from the bulk particles due to its unique physical and chemical properties [39][40][41]. In order to obtain a satisfied nanoscale modified layer, a high implantation dose range from 10 17 to 10 19 /cm 2 is required during implantation process [42][43][44][45]. The higher the implantation dose required, the faster the implantation efficiency caused, the better the properties achieved and the lower the production cost.…”

In this study, the effect of microstructure under various dose rates of plasma immersion ion implantation on 8Cr4Mo4V steel has been investigated for crystallite size, lattice strain and dislocation density. The phase composition and structure parameters including crystallite size, dislocation density and lattice strain have been investigated by X-ray diffraction (XRD) measurements and determined from Scherrer’s equation and three different Williamson–Hall (W-H) methods. The obtained results reveal that a refined crystallite size, enlarged microstrain and increased dislocation density can be obtained for the 8Cr4Mo4V steel treated by different dose rates of ion implantation. Compared to the crystallite size (15.95 nm), microstrain (5.69 × 10−3) and dislocation density (8.48 × 1015) of the dose rate of 2.60 × 1017 ions/cm2·h, the finest grain size, the largest microstrain and the highest dislocation density of implanted samples can be achieved when the dose rate rises to 5.18 × 1017 ions/cm2·h, the effect of refining is 26.13%, and the increment of microstrain and dislocation density are 26.3% and 45.6%, respectively. Moreover, the Williamson–Hall plots are fitted linearly by taking βcosθ along the y-axis and 4sinθ or 4sinθ/Yhkl or 4sinθ(2/Yhkl)1/2 along the x-axis. In all of the W-H graphs, it can be observed that some of the implanted samples present a negative and a positive slope; a negative and a positive slope in the plot indicate the presence of compressive and tensile strain in the material.

“…Several studies showed that nitrogen ion implantation could increase tribology properties such as hardness, wear resistance, fatigue life and corrosion resistance [4][5][6][7]. Some elements such as N, Ti, and Cr increase occurrence of new phase formation and microstructure alteration as well as the chemical and mechanical properties [8]. However, among those ions, the ion that is an interstitial solute which can contribute to the formation of Aluminium nitride phase on the surface [8].…”

However, among those ions, the ion that is an interstitial solute which can contribute to the formation of Aluminium nitride phase on the surface [8]. The importance of Aluminium nitride (AlN) is due to its excellent strength-to weight ratio, reasonably good corrosion resistance [9], extreme hardness, its electrical insulating properties (a band gap approximately 6.3 eV) and its high melting point (about 2400°C [10]).…”

The weakness of aluminium and its alloys are relative low hardness and wear resistance. To improve this weakness a nitrogen ion implantation technique has been carried out. For the purpose, an ion implantation process was carried out for various of dose such as 0.578×10 16 ion/cm 2 , 0.706×10 16 ion/cm 2 , 0.842×10 16 ion/cm 2 , 0.970×10 16 ion/cm 2 , and 1.106×10 16 ion/cm 2 at a certain energy and beam current, 60 keV and 75 µA, respectively. Hardness test was performed using microhardness tester, the corrosion resistance was tested using the electrochemical method, and the crystal structure was analyzed using X-ray diffraction. From the hardness test result, it can be concluded that the optimum hardness in order of 37.5 VHN was achieved at an ion dose of 0.83×10 17 ion/cm 2. While the hardness for the untreated sample was 18.70 VHN. It meant, there is an increasing hardness by a factor of 100,53%. At these conditions, the corrosion rate reduces from 0.012 mmpy to 0.011 mmpy or reduce by a factor of 8.3%. Based on the XRD analysis, it can be obtained the AlN phase is formed through the peaks at 2-theta was 39.37° (111), 45.76° (200), and 66.88° (202).
