“…[90] MGs also have no multiphase structures such as second phases, precipitates, and segregates which are associated with chemical heterogeneity and galvanic effects. [91] Investigation of metallic glassy ribbons, [90,93] electrodeposited amorphous alloys, [90,94] and BMGs [95] has confirmed the excellent electrochemical properties of MGs. MGs offer much greater range of solubility for alloying elements than crystalline alloys which could further extend electrochemical properties.…”

[91] Investigation of metallic glassy ribbons, [90,93] electrodeposited amorphous alloys, [90,94] and BMGs [95] has confirmed the excellent electrochemical properties of MGs. In addition to amorphous structure and complicated composition, the amount of surface area plays a very important role in electrochemical properties of MGs.…”

A large number of metallic glasses (MGs) with high mechanical and functional performance that cannot be achieved by traditional metals in various alloy systems have been developed. At the same time, people realized that micro-and nanoscale wires can improve properties and extend functionality of bulk materials. Therefore, intensive effort has been made to fabricate micro-and nanoscale MG wires, and study their mechanical and physical behavior to achieve high performance. This article reviews fabrication, properties and applications of the wires, and presents technical and theoretical challenges, which must be tackled to achieve high-performance MG wire devices and understand physical mechanisms of mechanical and functional behaviors of the wires.

“…Podesta et al [31] have studied amorphous NieCoeP alloys as electrocatalyst materials for water electrolysis in strongly alkaline solutions. CoO(OH), bCo(OH) 2 , as well as the amorphous products of oxidation of NieP alloy were found to play a major role during the oxygen evolution reaction [32]. The increased real surface area of NieCoeP alloys containing Fe and W greatly decreases the polarization for hydrogen evolution reaction in KOH solution [33].…”

“…Among magnetic amorphous materials, Cobased alloys are important and have been produced by various techniques including rapid quenching, 18,19) physical vapor deposition, 20) chemical or electroless plating 21,22) and electrodepostion. [23][24][25][26][27][28][29] The alloys produced by electrodepostion include Co-P, Co-W and Co-Ni-P etc. It is known that these Co-based magnetic alloys have relatively low saturation magnetization values below 1.0 T. Recently, Myung et al 30) have produced Co-Ni-P crystalline alloys having high cobalt and low phosphorus contents.…”

The composition, structure and magnetic properties of high cobalt-containing Co-Ni-P alloys have been examined by controlling electrodepostion parameters. The alloys were deposited at 323 K from an electroplating solution consisting of nickel and cobalt chlorides and sodium hypophosphite. The current density and pH of the solution were controlled to determine the conditions of forming amorphous films. The alloys prepared at a current density of 150 A/m 2 and pH of 5.20 include both amorphous and crystalline phases. The increase of pH to above 5.20 results in the formation of amorphous alloys without crystalline phase. The conditions of 220 A/m 2 for current density and 5.24 for pH were optimum to prepare the amorphous alloy at the highest deposition rate of 5:19 Â 10 À5 kg/m 2 /s. These amorphous alloys exhibited high saturation magnetization up to 1.3 T with coercivity of about 20 kA/m.
