Enhanced thermal stability and fracture toughness of TiAlN coatings by Cr, Nb and V-alloying
(Elsevier, 2018-05-25)
Article
Open AccessThe effect of metal alloying on mechanical properties including hardness and fracture toughness were investigated in three alloys, Ti~0.33Al0.50(Me)~0.17N (Me¿=¿Cr, Nb and V), and compared to Ti0.50Al0.50N, in the as-deposited ... -
Grinding effects on surface integrity and mechanical strength of WC-Co cemented carbides
(Elsevier, 2014)
Article
Open AccessIn this study, the correlation existing among grinding, surface integrity, and flexural strength is investigated for WC-Co cemented carbides (hardmetals). A fine-grained WC-13 wt % Co grade and three different surface ... -
Grinding-induced metallurgical alterations in the binder phase of WC-Co cemented carbides
(2017-12)
Article
Open AccessThe metallic binder phase dictates the toughening behavior of WC-Co cemented carbides (hardmetals), even though it occupies a relative small fraction of the composite. Studies on deformation and phase transformation of the ... -

Influence of microstructure and mechanical properties on the tribological behavior of reactive arc deposited Zr-Si-N coatings at room and high temperature
(Elsevier, 2016-10-25)
Article
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 ... -
Mechanical strength of ground WC-Co cemented carbides after coating deposition
(2017-03-24)
Article
Open AccessManufacturing of hardmetal tools often involves surface grinding, ion etching and final coating. Each stage throughout the manufacturing chain introduces surface integrity changes which may be critical for defining the ... -
