“…Nonequilibrium approaches, such as rapid solidification, could be an option to form a passivated Mg matrix phase(a metastable alloy). Among those non-traditional metallurgic methods [43][44][45][46], magnetron sputtering can produce single-phase, non-equilibrium Mg alloys in a wide composition range. It can thus be used to fabricate single-phase Mg-passivating element alloys to simulate the Mg matrices for studying the corrosion and passivation of Mg alloys.…”

This study explored the possibility of forming a "stainless" Mg-Ti alloy. The electrochemical behavior of magnetron-sputtered Mg-Ti alloys was measured in a NaCl solution, and the surface films on the alloys were examined by XPS, SEM and TEM. Increased corrosion resistance was observed with increased Ti content in the sputtered Mg-Ti alloys, but passive-like behavior was not reached until the Ti level (atomic %) was higher than the Mg level. The surface film that formed on sputtered Mg-Ti based alloys in NaCl solution was thick, discontinuous and nonprotective, whereas a thin, continuous and protective Mg and Ti oxide film was formed on a sputtered Ti-Mg based alloy.

“…This film could retard the formation of magnesium hydroxide . Similar corrosion behavior was observed for binary Mg‐Ti thin films . Moreover, it is necessary to obtain a homogeneous distribution of Ti element throughout the microstructure to attain good corrosion properties; otherwise, heterogeneous distribution of Ti could give rise to micro‐galvanic corrosion pairs between Ti‐rich and Ti‐poor regions .…”

SUMMARY Magnesium – nickel alloys have been considered an alternative for AB5 and AB2‐type alloys in nickel–metal hydride batteries due to their larger maximum discharge capacities, but their low stability in alkaline solution has hindered their use in commercial cells. Aiming to improve the electrode performance of the Mg55Ni45 alloy, we investigated the simultaneous addition of Ti and a noble metal (Pd and Pt) as alloying elements. The investigated system has general composition Mg49Ti6Ni(45‐x)Mx, where M is Pd or Pt, and x assumed values of 0, 2.0 and 4.0 at.%. The electrochemical measurements showed that the Mg49Ti6Ni41Pd4 alloy has the best electrode performance among the studied alloys, reaching 431 mA h g−1 of maximum discharge capacity at the first cycle of charge/discharge. After 10 and 20 cycles, this alloy presented relative discharge capacities of 84 and 77% of the initial one, respectively. The electrode performance of the investigated alloys is discussed in light of results of structural characterization by transmission electron microscopy and X‐ray diffraction.

“…Magnesium and magnesium alloys are considered as one of the lightest and attractive materials in the field of automotive, aerospace and medical industries for different applications. They are in need for the society due to the properties like low density, improved thermal and electrical conductivity, high specific stiffness, good machinability and vibration damping characteristics [1][2][3][4]. Some of the limitations that are included are poor tribological and corrosion properties which hindered the usage of magnesium and its alloys for different engineering applications [5].…”

The current study examines the wear performance of deformed AM90 magnesium alloy using pin-ondisc wear test apparatus under varying load of 30 and 40 N with the sliding distance of 2500 m and 5000 m at constant sliding speed of 3 m s −1 . The samples were processed through equal channel angular pressing were subjected to microstructural, wear studies and are characterized by optical and scanning electron microscopy. Vickers microhardness was carried out to evaluate the relation between the wear behavior of homogenized and ECAP processed samples. Increment in number of ECAP passes increased the grain refinement as observed in the microstructure with reduction in grain size from ∼70 μm (homogenized sample) to ∼4 μm (ECAP 4 pass sample). Increase in wear resistance and hardness were observed for processed samples and the worn faces are analyzed by scanning electron microscopy and energy-dispersive x-ray spectrometer. The worn surfaces revealed the occurrence of wear debris, delamination, ploughing in the direction of sliding and the predominant wear mechanism was considered to be the combination of oxidation and abrasive wear.
