Assessment of corrosion-induced changes on the mechanical integrity of cemented carbides at small length scales
(2019-11-01)
Article
Accés obertIn this work, the effect of corrosion-induced damage on the mechanical response of hardmetals was evaluated at small length-scale by means of nanoindentation and nanoscratch techniques. Damage was introduced in a controlled ... -
Contact fatigue behaviour of CVD coated cemented carbides in dry and wet conditions
(2022-03-15)
Article
Accés obertCycling contact fatigue indentation tests in dry and wet conditions were conducted in cemented carbides CVD-coated with Ti(C,N)/a-Al2O3 and Zr(C,N)/a-Al2O3 systems. In dry contact experiments, all imprints presented a ... -
