“…8a) [46]. The micro-galvanic corrosion promoted the evolution of localized corrosion [47,48]. To further understand the effect of FISS on localized corrosion, we statistically analyzed the localized corrosion coverage ratio ( LCCR ) and corrosion product removal coverage ratio ( CPRCR ) of samples at 50 μm depth intervals by 2-D cross section slices of CT data using Image-Pro ® Plus, as shown in Fig.…”

An in-situ and real-time electrochemical study in a vascular bioreactor was designed to analyze corrosion mechanism of magnesium alloy (MgZnCa) under mimetic hydrodynamic conditions. Effect of hydrodynamics on corrosion kinetics, types, rates and products was analyzed. Flow-induced shear stress (FISS) accelerated mass and electron transfer, leading to an increase in uniform and localized corrosions. FISS increased the thickness of uniform corrosion layer, but filiform corrosion decreased this layer resistance at high FISS conditions. FISS also increased the removal rate of localized corrosion products. Impedance-estimated and linear polarization-measured polarization resistances provided a consistent correlation to corrosion rate calculated by computed tomography.

“…In general, the corrosion rate of Mg alloys is affected by the precipitated phases significantly. Heat treatment is one of the effective methods to adjust the second phases and therefore to affect the mechanical properties, as well as corrosion properties of Mg alloys [13][14][15]. According to our previous work, it was confirmed that the mechanical properties were closely linked to the different precipitated phases in Mg 95.8 Gd 3 Zn 1 Zr 0.2 alloy with LPSO structure before and after heat treatment [3].…”

The microstructure of the precipitated phases of Mg 95.8 Gd 3 Zn 1 Zr 0.2 alloys with long-period stacking ordered structure before and after heat treatment is discussed. The corrosion properties of the as-cast (F), solid-solution (T4) and aging-treated (T6) alloys in 1% NaCl solution are studied. The hydrogen evolution and electrochemical measurements display that the as-cast Mg 95.8 Gd 3 Zn 1 Zr 0.2 alloy with the continuous network eutectic phase exhibits the greatest corrosion resistance, while T6 sample with some needle-like phases and the particle phases is the worst among the three alloys. It is proposed to be mainly related to the amount, composition, microstructure and distribution of the precipitated phases.

“…Therefore, it can be concluded from Figure 2 that the corrosion resistance of the alloy is improved with increasing aging times. Recent reports show that the corrosion resistance of Mg alloys subjected to solution and aging maybe related to many factors, including the morphology and distribution of precipitates, oxidation film on the surface, grain size etc [6][7][8][9][10]. The improved corrosion resistance of the present Mg-7%Li-4%Al-1%Zn alloy samples should also be attributed to the combined effects of above factors.…”

Abstract. Casting Mg-Li alloy samples were subjected to solid solution treatment with different temperatures and aging with different times, and the corrosion resistance of different samples was investigated by potentiodynamic polarization measurements in 3.5% NaCl solution. The results show that the corrosion resistance of the Mg-Li alloy is improved with increasing solution temperatures and aging times.
