Developing amorphous alloys with good corrosion resistance have attracted wide interests recently. In this work, a series of Fe71 ? xCrxMo3.5Ni5P10C4B4Si2.5 (x = 0, 4, 8, 10, 12, 14 at.%) amorphous alloys are fabricated. Thermal stability of this alloy system increases slightly with appropriate Cr content. The corrosion resistance in 3.5 wt.% NaCl solution is sensitive to the minor addition of Cr (≤4 at.%) whereas higher Cr does not significantly improve the corrosion resistance according to the results of electrochemical measurements, SEM and XPS. These Fe-based amorphous alloys show comparable corrosion resistance with the well-known amorphous steel (Fe48Mo14Cr15Y2C15B6) despite the low Cr and Mo content, making them good candidates as corrosion- resistant coating materials.

Subjects: Physics >> General Physics: Statistical and Quantum Mechanics, Quantum Information, etc.

SnOx films were fabricated by reactive rf magnetron sputtering under various oxygen partial pressures (PO = 1.6%–50%) and then annealed in an air ambient. Four operating window regions of the SnOx films are demonstrated such as metallic Sn dominated films with n-type conduction, polycrystalline SnO dominated films with p-type conduction, SnO-SnO2 composite films with high resistivity, and amorphous SnO2 dominated films with n-type characteristics. TFT devices using the SnO dominated films as channels are investigated. The TFTs with the channels of a hole concentration over 1018 cm?3 show depletion p-type characteristics. The hole concentration can be tunable by changing PO, the channel thickness, and the annealing durations. An ambipolar operating mode is obtained by modulating the hole concentration.

Magnetoinductance and magnetoimpedance response of Co-based multi-wire arrays

The magnetic circular permeability extracted from impedance measurements of arrays composed of Co- based amorphous wires was studied as a function of the number and distance between the wires. The results showed that a linear array with higher number of wires increased the permeability and thereby magnetoimpedance (MI) response up to 10 MHz. It was also proposed that such variation in circular permeability originated from the magnetostatic interaction among the wires gave rise to a change in the skin depth and finally in impedance. Increasing the distance between the wires had a detrimental effect on permeability and MI ratio due to a weaker mutual interaction. These observations provide support to the complex inductance formalism as an alternative approach to explain MI change in wire arrays.
