“…The observed formation of intermetallic Al-Cr phases is in agreement with the phase diagram, e.g. reported in [31]. As the cathode surface is repeatedly heated by the localised plasma in the cathode spots and then cooled down after extinction of the individual spot, the Al Cr hence, similar peak positions in the XRD patterns.…”

AlxCr1−x composite cathodes with Al contents of x = 0.75, 0.5 and 0.25 were exposed to cathodic arc plasmas in Ar, N2 and O2 atmospheres and their erosion behaviour was studied. Cross-sectional analysis of the elemental distribution of the near-surface zone in the cathodes by scanning electron microscopy revealed the formation of a modified layer for all cathodes and atmospheres. Due to intermixing of Al and Cr in the heat-affected zone, intermetallic Al-Cr phases formed as evidenced by X-ray diffraction analysis. Cathode poisoning effects in the reactive N2 and O2 atmospheres were non-uniform as a result of the applied magnetic field configuration. With the exception of oxide islands on Al-rich cathodes, reactive layers were absent in the circular erosion zone, while nitrides and oxides formed in the less eroded centre region of the cathodes.

“…In the Al-Cr-Nb-Ti-Zr system, four out of ten binaries have eutectic points, namely Al-Nb, Al-Zr, Cr-Zr, and Cr-Nb [64][65][66][67] . However, the absence of eutectic points in Al-Cr [68] , Nb-Zr [69] , and Ti-X (X = Al, Cr, Nb, Zr) [70][71][72][73] binaries suggests (in accord with the simple mixture approach [35] , frequently used for 3d transition metals EHEAs) that there are no eutectic compositions in quinary Al-Cr-Nb-Ti-Zr system. Moreover, only in the Cr-Zr and Cr-Nb binaries, eutectics are composed of the bcc and Laves phases.…”
