“…In the ATR–IR spectra, the bare alloy showed a peak at 624 cm –1 , which signifies the presence of Mg–O. In the coating, the broad peak at 3240 cm –1 indicates the presence of stretching vibration of −OH . Specifically, the absorption of water on the coating’s surface is identified at 1384 and 1502 cm –1 by the stretching mode of −OH .…”

The removal of tumors in the osseous tissue leads to functional disorders. To overcome this issue, biodegradable implants are used to replace the damaged part of the system. In the study, samarium oxide was coated on the anodic layer of AZ31 magnesium alloy. The potentiodynamic polarization, electrochemical impedance, and localized electrochemical impedance spectroscopy studies were carried out for the samarium-coated magnesium alloy. The corrosion resistance of the coating improved several folds than the bare alloy. The apatite formed on the 3rd day of immersion in the simulated body fluid showed cuboid and triangular structures, whereas on the 7th day, it exhibited a sea sponge-like appearance. The coating exhibited inherent anticancer and antibacterial properties. Our work suggests that the samarium coating is expected to be a promising orthopedic implant for preventing tumor relapse and metastasis.

“…In this way, the 2FI model is the best choice for Ca/P. Analysis of variance (ANOVA) was utilized in the evaluation of the developed models (El Ouahli et al, 2019), as summarized in Tables 4 and 5 for Ca/P molar ratio and the size of deposited HA crystals, respectively. As can be seen, both models have a p-value <0.05 indicating that the models are significant.…”

PurposeThis study aims to investigate the effect of electrodeposition parameters (i.e. time and voltage) on the properties of hydroxyapatite (HA) coating fabricated on Ti6Al4V surface.Design/methodology/approachA full factorial design along with response surface methodology was utilized to evaluate the main effect of independent variables and their relative interactions on response variables. The effect of electrodeposition voltage and deposition time on HA coatings Ca/P molar ratio and the size of deposited HA crystals were examined by structural equation modeling (SEM). The formation of plate-like and needle-like HA crystals was observed for all experiments.FindingsThe results obtained showed that the higher electrodeposition voltage leads to lower Ca/P values for HA coatings. This is more significant at lower deposition times, where at a 20-minute deposition time, the voltage increased from 2 to 3 V and the Ca/P decreased from 2.27 to 1.52. Full factorial design results showed that electrodeposition voltage has a more significant effect on the size of the deposited HA crystal. With increasing the voltage from 2 to 3 V at a deposition time of 20 min, the HA crystal size varied from 99 to 36 µm.Originality/valueThe investigation delved into the impact of two critical parameters, deposition time and voltage, within the electrodeposition process on two paramount properties of HA coatings. Analyzing the alterations in coating characteristics relative to variations in these process parameters can serve as a foundational guide for subsequent research in the domain of calcium-phosphate deposition for implants.
