This paper proposes the bio-fabrication of a porous scaffold from a selection procedure of elements taking into account biological behavior, using magnesium (Mg) alloyed with calcium (Ca) and zinc (Zn). The proposed scaffold could work as a treatment for specific pathologies in trauma and oncology, on the one hand, in addition to possible applications in osteosynthesis, through contrib-uting to osseointegration and infection control through the release of drugs. Finally, another pos-sible attribute of this alloy could be its use as a complementary treatment for osteosarcoma; this is due to the basification produced by oxidative degradation (attack on cancer cells). The evaluation of cell viability of an alloy of Mg - 25 wt% Ca - 5 wt% Zn will strengthen current perspectives on the use of Mg in the clinical evaluation of various treatments in trauma and oncology. Considera-tions on the preparation of an alloy of Mg - 25 wt% Ca - 5 wt% Zn and its morphological charac-terization will help researchers understand its applicability for the development of new surgical techniques and lead to a deeper investigation of alternative treatments. However, it is very im-portant to bear in mind the mechanical effect of elements such as Ca and Zn on the degradation of the alloy matrix; the best alternative to predict the biological-mechanical potential starts with the selection of the essential-nutritional elements and their mechanical evaluation by mi-cro-indentation due to the fragility of the matrix. Therefore, the morphological evaluation of the specimens of Mg - 25 wt% Ca - 5 wt% Zn will show the crystallinity of the alloy; these results to-gether contribute to the design of biomedical alloys for use in treatments for various medical spe-cialties. The results indicated that cell viability is not affected, and there are no morphological changes in the cells.

“…According to the obtained results, it was found out that sample of Z1 has the least corrosion current density (8.2 nA/cm 2 ) and thus has the highest corrosion resistance (3.59 MΩ.cm 2 ) and sample of Z2 has the highest corrosion current density (25.49 nA /cm 2 ) and as a result has the least corrosion resistance (0.67 MΩ.cm 2 ). Porosity is one of the most important defects in coatings that plays a crucial role in the corrosion resistance of coatings, as the corrosive electrolyte can penetrate into the coating through these porosities and eventually reach the substrate by destroying the coating [68]. As can be seen in Table 3, the calculated porosity percentage is shown using Equation (8).…”

In this paper, the plasma electrolyte oxidation (PEO) technique was applied to modify the AZ31B Mg alloy surface. Effects of various concentrations of ZnO nanoparticles into an electrolyte with nanoparticles of hydroxyapatite (HAp) on the antibacterial and corrosion behavior of coatings were studied. Potentiodynamic polarization tests were done in Ringer's electrolyte to study the coatings corrosion behavior. Results of XRD indicated that the provided PEO films mostly have phases of HAp, MgO, and Mg 3 (PO 4 ) 2 and ZnO. The results indicated that increasing the concentration of ZnO nanoparticles raised the thickness, roughness, and wetting angle and also enhanced the coatings antibacterial activity. The inhibition percentage of bacterial growth for the specimen with the highest concentration of nanoparticles (4 g/L) after 6 h against E. coli and S. aureus was 23.5% and 45.5%, respectively. The concentration of nanoparticles had no major effect on the porosity size of the ceramic coating. Moreover, adding ZnO nanoparticles declined the corrosion current density and raised the corrosion potential with regard to the metal substrate. The formed coating in the solution containing 1 g/ L ZnO nanoparticles had the highest corrosion behavior among all of specimens that led to a 970 multiplication corrosion resistance of AZ31B Mg alloy.

“…CCC is the one of common and effective physical barriers for the surface protection of MA (Saji, 2021), and the main products of CCCs include chromate conversion coating (Zhou et al , 2019c), phosphate conversion coating (PCC) (Xiong et al , 2015), rare earth conversion coating (Zhou et al , 2021b), stannate conversion coating (Lu et al , 2021), silane conversion coating (Zhou et al , 2021a), fluoride conversion coating (Zhang et al , 2021), manganate conversion coating (Jian et al , 2020) and so on. Compared with other CCCs, the obvious advantage of PCC is that it takes both low cost and low harm into consideration at the same time (Chaharmhali et al , 2021).…”

“…Compared with other CCCs, the obvious advantage of PCC is that it takes both low cost and low harm into consideration at the same time (Chaharmhali et al, 2021). About PCCs, single phosphate conversion coating (SPCC), which contains only one metal element, is reported repeatedly, such as calcium (Ca)@SPCC (Su et al, 2016), magnesium (Mg) @SPCC (Ishizaki et al, 2009), manganese (Mn)@SPCC (Chen et al, 2013) and zinc (Zn)@SPCC (Xiong et al, 2017); in recent years, composite phosphate conversion coating (CPCC), which contains several metal elements, begins to be concerned (Liu et al, 2015;Zhang et al, 2020;Hafeez et al, 2020).…”

Purpose The aim of this work was to propose a method to prepare composite phosphate conversion coating (CPCC), including ternary phosphate conversion coating (TPCC) and binary phosphate conversion coatings (BPCC), with one-step chemical conversion and to reveal and compare the corrosion resistance between TPCC and BPCC. Design/methodology/approach In this work, a calcium–manganese–zinc (Ca–Mn–Zn) TPCC was prepared on the surface of magnesium alloy (MA) AZ91D with one-step chemical conversion method; for Ca-Mn-Zn@TPCC, its microstructure was characterized with scanning electron microscope observation and scanning tunneling microscope detection, and its composition was characterized with energy dispersion spectroscopy and X-ray photoelectron spectroscopy analyses. Particularly, the corrosion resistance of Ca-Mn-Zn@TPCC and its comparison with Ca–Mn, Ca–Zn and Mn–Zn BPCCs were clarified with electrochemical and immersion measurements. Findings Ca-Mn-Zn@TPCC, which was composed of Ca, Mn, Zn, P and O, exhibited a mud-shaped with cracks microstructure, and the average crack width, terrain fluctuation and coating thickness were 0.61 µm, 23.78 nm and 2.47 µm, respectively. Ca-Mn-Zn@TPCC provided good corrosion resistance to MA AZ91D; in NaCl solution, the total degradation of Ca-Mn-Zn@TPCC consumed eight days; corrosion products with poor adhesion peeled out from Ca-Mn-Zn@TPCC-coated MA AZ91D spontaneously. Besides, the corrosion resistance of Ca-Mn-Zn@TPCC was better than that of Ca-Mn@BPCC, Ca-Zn@BPCC or Mn-Zn@BPCC. Originality/value The successful preparation of Ca-Mn-Zn@TPCC on MA AZ91D surface confirmed the proposed method to prepare CPCC with one-step chemical conversion was feasible; at the same time, it was further confirmed that for phosphate conversion coating, ternary coating had better corrosion resistance than binary coating did.
