Growth and thermal stability of TiN/ZrAlN: Effect of internal interfaces
Yalamanchili, Kumar; Wang, Fei; Aboulfadl, Hisham; Barrirero, Jenifer; Rogstrom, Lina; Jiménez Piqué, Emilio; Mücklich, F.; Tasnadi, Ferenc; Odén, Magnus; Ghafoor, N (2016-12-01)
Article
Accés obertWear resistant hard films comprised of cubic transition metal nitride (c-TMN) and metastable c-AlN with coherent interfaces have a confined operating envelope governed by the limited thermal stability of metastable phases. ... -
Influence of microstructure and mechanical properties on the tribological behavior of reactive arc deposited Zr-Si-N coatings at room and high temperature
Yalamanchili, Kumar; Jiménez Piqué, Emilio; Pelcastre, L.; Roa Rovira, Joan Josep; Johansson Joesaar, M.P; Prakash, Bhanu; Ghafoor, N; Odén, Magnus (Elsevier, 2016-10-25)
Article
Accés obertVarying the Si-content in Zr-Si-N coatings from 0.2 to 6.3 at.% causes microstructural changes from columnar to nanocomposite structure and a hardness drop from 37 to 26 GPa. The softer nanocomposite also displays lower ...
