“…The passivation layers of the representative regions (HAZ and SZ) were composed of metallic oxide mixtures, such as Al 2 O 3 , MgO, and ZrO 2 , which presented a mediate passivation effect. Moreover, there appeared to be some fluctuations in the OCP curves, which were caused by the dissolution–regeneration process of the passivation layers [30].…”

Friction stir welding (FSW) with a Zr interlayer was employed to join dissimilar alloys of 6061 Al and AZ31 Mg. The microstructures of Al/Mg and Al/Zr/Mg joints were investigated by optical microscopy (OM), scanning electron microscopy (SEM), and energy dispersive X-ray spectrometer (EDS). The results showed that the central part of the Zr interlayer was smashed and intermixed with the base materials in the stir zone, whereas the undamaged part remained stable at the Al/Mg interface. The formation of Al–Mg intermetallic compounds (IMCs) was suppressed by the Zr interlayer due to its synergetic effects of chemical modification and thermal barrier. The electrochemical measurements revealed a differentiated corrosion behavior for each joint, where the corrosion rate of representative regions increased in the order of Al alloy < Mg alloy < heat-affected zone < stir zone. The immersion tests indicated an enhancement in corrosion resistance for the Al/Zr/Mg joint compared with the Al/Mg joint, which is owing to the mitigated galvanic corrosion between the base materials by the Zr interlayer.

“…Surface modification can effectively enhance the corrosion performance of Mg alloy and, at the same time, can impart different biological properties to the surface. − Different surface modification methods such as electrodeposition, microarc oxidation (MAO), ion implantation, anodized oxidation, chemical conversion coating, and polymer coating have been widely used. Among these methods, chemical conversion coating, especially Ca–P conversion coating, is one of the most widely used and effective methods, which can simultaneously enhance the biocompatibility and corrosion resistance of Mg alloys. , …”

Magnesium (Mg) and its alloys have exhibited great potential for orthopedic applications; however, their poor corrosion resistance and potential cytotoxicity have hindered their further clinical applications. In this study, we prepared a calcium phosphate (Ca−P) coating with a micro−nanofibrous porous structure on the Mg alloy surface by a chemical conversion method. The morphology, composition, and corrosion performance of the coatings were investigated by scanning electron microscope (SEM), energy-dispersive spectrometer (EDS), X-ray diffraction (XRD), immersion tests, and electrochemical measurements. The effects of the preparation temperature of the Ca−P coatings were analyzed, and the results confirmed that the coating obtained at 60 °C had the densest structure and the best corrosion resistance. In addition, a systematic investigation into cell viability, ALP activity, and cell morphology confirmed that the Ca−P coating had excellent biocompatibility, which could effectively promote the proliferation, differentiation, and adhesion of osteoblasts. Hence, the Ca−P coating demonstrates great potential in the field of biodegradable Mg-based orthopedic implant materials.

“…Magnesium alloys are widely used in many fields because of their light weight, good damping capacity, and recycling potential [1][2][3]. Unfortunately, the corrosion resistance of magnesium alloys in many engineering applications is insufficient [4,5] and methods such as micro-arc oxidation [6,7], laser cladding [8,9], plasma electrolytic oxidation [10,11] and ion implantation [12][13][14][15] have been proposed to improve the corrosion properties. For example, Zn [16,17], Zr [18], Nd [19], C 2 H 2 [20] and Si [21] ion implantations have been conducted on Mg alloys to improve the surface properties [17,22].…”

Ti, Ni, and Ti/Ni plasma immersion ion implantation is carried out on the AM60 magnesium alloy with a 6 × 1016 ions/cm2 fluence and energy of 35 keV. The corrosion and wear properties of the ion-implanted samples are determined systematically by X-ray photoelectron spectroscopy, X-ray diffraction, scanning electron microscopy, electrochemical methods and wear tests. A Ni-rich layer composed of α-Mg, Ni2O3, and NiTi2 is formed on the surface after dual Ti/Ni ion implantation, and the ion implantation range is approximately 300 nm. The corrosion resistance of the Ni- and Ti/Ni-implanted AM60 samples is significantly reduced in the 3.5% NaCl solution. However, NiTi2 does not adhere well to the grinding ring during the wear test due to the bonding properties, and the sample implanted with both Ti and Ni shows the best wear resistance.
