“…The DSC data for Zr 40.5 Ni 59.5 (Fig. 3a) shows a peak temperature at 467°C, lower than the reported crystallisation temperatures for Zr 36 Ni 64 (around 550°C) [9,14]. The lower crystallisation temperature observed in the present work may be due to the internal stress in the thin film structure and an increased Zr content of this alloy, both of which have a known effect in lowering the thermal stability [14,16,20].…”

“…The use of amorphous materials for hydrogen separation membrane can address several problems associated with the use of crystalline materials such as hydrogen embrittlement and high cost [6]. Some of the amorphous zirconium-based membranes, and in particular Zr 36 Ni 64 , Zr 54 Cu 46 , and Zr 30 Cu 60 Y 10 alloys, have been shown by computational [7,8] and experimental studies [9,10] to have hydrogen permeability values close to that of Pd.…”

“…In addition, the use of low bias voltage on the work piece allows the deposition of films at a low temperature, which could be beneficial when attempting to produce amorphous alloys. This work will investigate the possibility of using this particular type of magnetron sputtering, (CFUMSIP) [19], to fabricate thin amorphous films of Zr 36 Ni 64 , Zr 54 Cu 46 , and Zr 30 Cu 60 Y 10 alloys, due to their comparable hydrogen permeability to Pd [7][8][9][10]. Structure, composition, surface morphology and thermal stability of the alloys will be assessed.…”

a b s t r a c tAmorphous hydrogen separation membranes are under development because of their resistance to hydrogen embrittlement, improved mechanical properties, resistance to corrosion and most importantly lower intrinsic cost. The Closed Field Unbalanced Magnetron Sputter Ion Plating (CFUBMSIP) is a versatile technique for deposition of high quality thin-films of almost any composition, while enabling the control of film size, thickness and shape. In this work, it was demonstrated that thin-films ($3-6 lm) of amorphous Zr 40.5 Ni 59.5 , Zr 54 Cu 46 and Zr 30 Cu 57.5 Y 12.5 could be deposited onto glass substrates by the CFUBMSIP technique. XRD measurements only showed one broad peak for each alloy, with a peak centred between 36°and 42°2h, indicating that the films were amorphous. Surface analysis by SEM and confocal microscopy suggest deposition of continuous films. The thermal stability of the films appears to be mainly governed by the alloying elements and their compositions. However, the measured activation energies indicated that the nucleation and growth mechanism in the magnetron sputtered films may be different from that reported for melt-spun amorphous alloys with similar compositions.

Developments in the Ni–Nb–Zr amorphous alloy membranes

Most of the global H2 production is derived from hydrocarbon-based fuels, and efficient H2/CO2 separation is necessary to deliver a high purity H2 product. Hydrogen-selective alloy membranes are emerging as a viable alternative to traditional pressure swing absorption processes as a means for H2/CO2 separation. These membranes can be formed from a wide range of alloys, and those based on Pd are the closest to commercial deployment. The high cost of Pd (USD ~31,000 kg -1 ), however, is driving the development of less-expensive alternatives, including inexpensive amorphous (Ni60Nb40)100-xZrx alloys. Amorphous alloy membranes can be fabricated directly from the molten state into continuous ribbons via melt spinning, and depending on the composition, can exhibit relatively high hydrogen permeability between 473 and 673 K. Here we review recent developments in these low-cost membrane materials, especially with respect to permeation behavior, electrical transport properties, and understanding of local atomic order. In a quest to further understand the nature of these solids, atom probe tomography has been performed, revealing amorphous Nb-rich and Zr-rich clusters embedded in, majority Ni matrix, whose compositions deviated from the nominal overall composition of the membrane.
