Fatigue susceptibility under contact loading of hardmetals coated with ceramic films
(2010-04)
Article
Restricted access - publisher's policyThe contact fatigue behavior of a fine-grained hardmetal coated with two distinct ceramic films, either a TiN monolayer or a WC/C multilayer, is studied by means of indentation testing techniques. Spherical indentation ... -
Fatigue testing and properties of hardmetals in the gigacycle range
(2017-01-01)
Article
Open AccessHardmetal products are frequently fatigue loaded in service, such as e.g. cutting tools for milling or percussion drills. In the present work, the fatigue behaviour of hardmetals was investigated into the gigacycle range ... -
FIB/FESEM experimental and analytical assessment of R-curve behavior of WC-Co cemented carbides
(2015-10-01)
Article
Open AccessExceptional fracture toughness levels exhibited by WC-Co cemented carbides (hardmetals) are due mainly to toughening derived from plastic stretching of crack-bridging ductile enclaves. This takes place due to the development ... -
