“…Magnesium (Mg) alloys have been widely applied as lightweight engineering materials due to their unique properties [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 ]. As commercial Mg-Zn-based alloys, ZK60 (Mg–Zn–Zr) alloys [ 9 ] have attracted great interest from researchers due to their high strength [ 10 , 11 , 12 ].…”

In this work, the effects of the microstructure and phase constitution of cast magnesium alloy ZK60 (Mg-5.8Zn-0.57Zr, element concentration in wt.%) on the corrosion behavior in aqueous NaCl (0.1 mol dm−3) were investigated by weight-loss measurements, hydrogen evolution tests, and electrochemical techniques. The alloy was found to be composed of α-Mg matrix, with large second-phase particles of MgZn2 deposited along grain boundaries and a Zr-rich region in the central area of the grains. The large second-phase particles and the Zr-rich regions were more stable than the Mg matrix, resulting in a strong micro-galvanic effect. A filiform corrosion was found. It originated from the second-phase particles in the grain boundary regions in the early corrosion period. The filaments gradually occupied most areas of the alloy surface, and the general corrosion rate decreased significantly. Corrosion pits were developed under filaments. The pit growth rate decreased over time; however, it was about eight times larger than the general corrosion rate. A schematic model is presented to illustrate the corrosion mechanism.

“…The corrosion behaviours of alloys were investigated in Hank's solution at 37°C. The composition of Hank's solution, details of the procedure, design and the corrosion rate of the specimen can be found elsewhere [25]. The samples with Φ 20 × 10 mm for the weight loss and the hydrogen evolution experiments were polished to #3000.…”

To develop a biomedical magnesium alloy with desirable mechanical properties and corrosion resistance, Mg-6Zn-8.16Y-2.02Mn and Mg-6Zn-8.16Y-2.02Mn-0.3Mo alloy were prepared. Then the alloys were solution-treated at 500°C for 40 h and cooled in the furnace. The results showed that partly 18R-long-period stacking ordered (LPSO) phase transformed to 14H-LPSO phase during solid-solution treatment. The hollowed-out W phase vanished and spherical W phase was formed. And the volume fraction of 18R-LPSO and the average size of the spherical W phase particles were reduced. Corrosion behaviour of the alloy in Hank's solution under each condition was studied by immersion test and electrochemical test. The solution-treated Mg-6Zn-8.16Y-2.02Mn-0.3Mo alloy exhibited the best mechanical property (ultimate tensile strength, UTS 270 MPa and elongation, EL 23%) and corrosion resistance (P W 1.03 mm/year and I corr 0.20 mm/year) due to fine and homogeneous microstructure.

“…[10] To compensate for lithium volatility, some research groups add 15 wt.% excess Li 2 O to PLD targets. [11] A number of studies have focused on LiCoO 2 , impurities and its high temperature polymorph or HT LiCoO 2 , [12] understanding the growth conditions (e. g. 600°C for HT [12] and 250-330°C for LT [13] ) and the type/quality of films synthesized. [14a,b,c] Additionally work has shown failure mechanisms including dissolution of the cations, mechanical failure and phase transitions, e. g. in the case of HT LiCoO 2 to the spinel Co 3 O 4 or LiCo 2 O 4 .…”

Emerging applications for robust small format or distributed devices feature a need for power and rechargeable lithium-ion batteries could play a significant role. This review focuses on a high precision technique to controllably grow thin-film electrodes or full all-solid-state batteries, that is, pulsed laser deposition (PLD). The technique and solidstate batteries are introduced followed by a detailed showcase of the depth of PLD-based growth undertaken on cathodes, electrolytes, anodes and whole microbatteries. Emphasis is placed on the various characterization techniques available to study PLD grown components and devices, and how interfaces become both critical and arguably easier to probe in PLD grown films or devices. This work provides a perspective on the techniques, its opportunities for electrodes and devices, and how to probe the resulting growth and its evolution in batteries.
