      Polychronopoulou, K.; Rebholz, Claus; Demas, N. G.; Polycarpou, A. A.; Gibson, P. N. (Affiliation: Department of Mechanical and Manufacturing Eng., University of Cyprus, Nicosia, CyprusAffiliation: Department of Mechanical Science and Eng., University of Illinois at Urbana-Champaign, Urbana, IL, United StatesAffiliation: Institute for Health and Consumer Protection, Joint Res. Centre of the European Commission, Ispra (VA), ItalyCorrespondence Address: Polychronopoulou, K.Department of Mechanical and Manufacturing Eng., University of Cyprus, Nicosia, Cyprus, 2010)
      Cr-N and Cu-Cr-N coatings with Cu content between 3-65 at.%, Cu/Cr ratios in the 0.04-4.5 range and 21-27 at.% N, synthesized by twin e-beam Physical Vapor Deposition (EBPVD) at 450°C, were investigated. Using X-ray ...
