Magnesium alloys have been considered to be favorable biodegradable metallic materials used in orthopedic and cardiovascular applications. We introduce NH + 2 to the AZ31 Mg alloy surface by ion implantation at the energy of 50 KeV with doses ranging from 1×10 16 ions/cm 2 to 1×10 17 ions/cm 2 to improve its corrosion resistance and biocompatibility. Surface morphology, mechanical properties, corrosion behavior and biocompatibility are studied in the experiments. The analysis confirms that the modified surface with smoothness and hydrophobicity significantly improves the corrosion resistance and biocompatibility while maintaining the mechanical property of the alloy.

“…Aer 7 days of immersion, the two time constants seem to be inextricable, which suggests that the silane coating has lost its barrier property. 31 According to the phase angles in Fig. 3b, the bare sample reveals positive angles aer an hour of immersion in low frequencies (between 10 À1 and 10 À2 ), which is eloquent of an inductive loop.…”

“…As shown in Figure 3b,c, the strong absorption peaks at 3695 cm −1 on the LPS/Mg surfaces and CWRSs were related to the O–H stretching in the Mg(OH) 2 layer, and the intensity of the peak was proportional to the increase in ambient temperature. [ 27,28 ] In particular, this absorption peak was not observed on the LPS, indicating the formation of Mg(OH) 2 on the LPS after HM. The diffraction peaks corresponding to –CH 3 and –CH 2 were observed at 2923 and 2853 cm −1 of the four groups of CWRSs.…”

Magnesium (Mg) alloys have poor corrosion resistance, higher requirements for corrosion resistance of the coating, and the changes in the environment in the actual application are complicated and diverse. Therefore, it is urgent to develop bio‐inspired water‐repellent surfaces (WRSs) with long‐lasting corrosion resistance and multiple excellent properties for Mg alloys. In this study, a composite water‐repellent surface (CWRS) with long‐lasting corrosion resistance and self‐cleaning behavior is prepared by combining laser processing, hydrothermal treatment, and immersion method on the Mg alloy surface. The effect of ambient temperature changes on the wettability and corrosion resistance of the CWRS is investigated. The experimental results showed that a uniform and dense CWRS with a film thickness of 36 μm could be prepared on the Mg alloy surface at an ambient temperature of 180 °C, demonstrating excellent corrosion resistance and self‐cleaning behavior. In addition, in the harsh salt spray test, it is found that even if the superhydrophobicity of the CWRS was lost, the surface still has good corrosion resistance. Multifunctional CWRSs have become a research hotspot, and it is of great significance to promote the application of Mg alloys in actual working conditions.
