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; Oden, M (Elsevier, 2016-10-25)
Open AccessVarying 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 ...
