Contact damage resistance of TiN-coated hardmetals: Beneficial effects associated with substrate grinding
(2015-08-15)
Article
Open AccessContact loading is a common service condition for coated hardmetal tools and components. Substrate grinding represents a key step within the manufacturing chain of these coated systems. Within this context, the influence ... -
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 ... -
Implementation of advanced characterization techniques for assessment of grinding effects on the surface integrity of WC-Co cemened carbides
(2018)
Article
Open AccessGrinding is a key step on the manufacturing process of WC–Co cemented carbides (hardmetals). In this work, an investigation of grinding effects on the surface integrity of hardmetals is conducted. It is done by combining ... -
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 ... -
Structure, deformation and fracture of arc evaporated Zr-Si-N hard films
(2014-11-15)
Article
Restricted access - publisher's policyZr-Si-N films with varying Si contents were grown on WC-Co substrates by reactive cathodic arc deposition technique. The resulting microstructures of the films correlate to dominant variation in mechanical properties and ... -
Substrate surface finish effects on scratch resistance and failure mechanisms of TiN-coated hardmetals
(Elsevier, 2015-03-15)
Article
Open AccessIn this study, the influence of substrate surface finish on scratch resistance and associated failure mechanisms is investigated in the case of a TiN-coated hardmetal. Three different surface finish conditions are studied: ...
