Summary: Magnesium, zinc, or iron alloys without toxic elements are attractive as construction materials for biodegradable implants. The synergistic effects of mechanical stress and corrosive human body fluid can lead to sudden and catastrophic fractures of bioimplants, such as stress corrosion cracking and corrosion fatigue. However, there has been limited investigation into SCC and CF of zinc-based implants. This article provides an overview of the challenges, research needs, and future directions in understanding SCC and CF of zinc alloys in human body fluid.

Summary: Zn-Li-based alloys have high monotonic strength and better pitting resistance, but their response to dynamic loadings is still unknown. The corrosion fatigue behavior of Zn-Li binary alloys with different lithium addition amounts was tested, and it was found that the corrosion fatigue strength was not proportional to lithium content. Zn-Li binary alloys showed comparable fatigue strength to pure iron and pure titanium, confirming their loading capacity under dynamic conditions.

Summary: The study investigates the effect of hydrofluoric acid treatment on the corrosion and stress corrosion cracking (SCC) susceptibility of Mg-Zn-Ca alloy. It is found that the treatment significantly reduces the corrosion rate and SCC susceptibility of the alloy. The improvement in corrosion and SCC performance is attributed to the formation of a protective surface film, removal of surface contaminations, and dissolution of secondary phase particles.

Summary: Magnesium and its composites, including magnesium/hydroxyapatite (Mg/HA), were subjected to corrosion-fatigue tests in a high cycle regime. The composites exhibited better corrosion resistance and more promising fatigue behavior compared to pure magnesium. The composite containing 5 wt.% hydroxyapatite showed the highest tensile and compressive yield strengths, as well as the most promising high cycle fatigue behavior.

Summary: In this study, the surface of AZ80 Mg alloy was modified by two treatment methods, MAO and LSP/MAO, to improve its corrosion resistance and mechanical properties in simulated body fluid. The LSP/MAO composite coating showed superior stress corrosion cracking resistance compared to MAO alone, which could help extend the service life of Mg alloy implants.

Summary: By investigating the corrosion behavior of different orientation samples of magnesium alloy immersed in simulated body fluid, it was found that the P-TD sample exhibited the best corrosion resistance, while the P-ND30 and P-ND60 samples showed similar corrosion behavior. A degradation evolution model was established, and the influence of initial orientation on corrosion behavior was discussed.

Summary: The study demonstrates that stress-corrosion cracking (SCC) in magnesium and its alloys during slow-strain rate tensile testing in air is related to hydrogen embrittlement and the corrosion product layer. However, the complete recovery of mechanical response and elimination of harmful embrittling features can be achieved by removing corrosion products from the surface of pre-exposed specimens, which challenges the common viewpoint that SCC mechanism is solely governed by diffusible hydrogen.

Summary: This study focuses on the corrosion behavior of two Mg-Zn-Ag alloys (Mg7Zn1Ag and Mg6Zn3Ag) and the Mg1Ca alloy. The experimental results show that simulated body fluid solution (SBF) exhibits a more corrosive nature, and alloys with a higher percentage of silver (2.5 wt.%) demonstrate better corrosion resistance. We consider that the magnesium alloy Mg6Zn3Ag has valuable biodegradation characteristics that can be considered as raw materials for manufacturing small trauma implants.

Summary: This study characterized highly open-porous Mg-based scaffolds at different scales and found that they exhibited a higher connected structure and smaller spacing compared to trabecular bone. The Mg scaffolds showed lower local strain and highly ductile mechanical behavior, making them suitable for use as a treatment for critical-sized bone defects.

Summary: This study evaluates the corrosion inhibition efficiency of thioridazine hydrochloride (TH), an antipsychotic drug, on mild steel in 1 M hydrochloric acid. The results show that TH significantly enhances the polarization resistance and reduces the corrosion current density of mild steel. Long-term exposure tests demonstrate that TH has a highly effective corrosion inhibition effect on mild steel.

Summary: Magnesium is a promising candidate metal for biodegradable implants due to its biodegradation tendency and excellent biocompatibility. However, the high degradation rate and localized degradation in physiological conditions are major challenges for its successful implant applications. Recent research has focused on coating hydroxyapatite (HAp), a biocompatible ceramic material, on magnesium-based materials to improve degradation resistance and biocompatibility.

Summary: This study investigates the degradation pattern of magnesium (Mg) alloys used as bone substitutes. It found that in situ cyclic compression accelerated the corrosion rate, but no critical failures in mechanical integrity were observed. The accumulation of corrosion products led to structural changes and changes in mechanical properties.
