Influence of the test configuration and temperature on the mechanical behaviour of WC-Co
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-03-01)
Article
Open AccessIn this work, the effect of the test configuration and temperature on the mechanical behaviour of cemented carbides (WC-Co) with different carbide grain sizes (dWC) and cobalt volume fractions (VCo), implying different ... -
3M en pantalla (mitos y mentiras sobre metales en pantalla)
(Sociedad Española de Materiales, 2020-05)
Article
Open AccessLos metales han formado parte de la evolución de la humanidad desde la antigüedad. Han sido objeto de culto, por escasos y exclusivos, y han sido la clave del desarrollo de armas, para, progresivamente, formar parte de los ... -
Contact damage investigation of CVD carbonitride hard coatings deposited on cemented carbides
(2020-01-01)
Article
Restricted access - publisher's policyThe evolution of damage induced as contact load is increased has been investigated on single- and multilayered coated cemented carbides by means of spherical indentation. The main objective of the study was to assess the ... -
Micromechanical investigations of CVD coated WC-Co cemented carbide by micropillar compression
(Elsevier, 2020-01-15)
Article
Open AccessDeformation behavior of an industrial coated cemented carbide (WC-Co substrate coated with CVD multilayer of TiN/Zr(C,N)/Ti(C,N,O)/Al2O3) was investigated by means of micropillar compression method. In addition to the WC-Co ... -
Corrosion-induced damage and residual strength of WC-Co,Ni cemented carbides: influence of microstructure and corrosion medium
(Multidisciplinary Digital Publishing Institute (MDPI), 2019-09-19)
Article
Open AccessThe corrosion behavior of cemented carbides with binders of different chemical nature (Co and Ni) and carbides with distinct mean grain size (ultrafine and coarse) was studied. The investigation also included corrosion ... -
Implementation of advanced characterization techniques for assessment of grinding effects on the surface integrity of WC-Co cemented carbides
(2018-02-21)
Article
Restricted access - publisher's policyGrinding 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 ... -
Laser surface texturing of a WC-CoNi cemented carbide grade: surface topography design for honing application
(2018-06)
Article
Open AccessAbrasive effectiveness of composite-like honing stones is related to the intrinsic surface topography resulting from the cubic boron nitride (CBN) grains protruding out of the metallic matrix. Within this framework, Laser ... -
Low temperature degradation of laser patterned 3Y-TZP: enhancement of resistance after thermal treatment
(Elsevier, 2018-04)
Article
Open AccessThe aim of this study is to characterize the resistance to low temperature degradation (LTD) of the surface of dental-grade zirconia (3Y-TZP) patterned with a Nd:YAG laser (532. nm harmonic and pulse duration of 10. ns) ... -
Scale effect in mechanical characterization of WC-Co composites
(2018-04-01)
Article
Open Access© 2017 Elsevier LtdThe study of mechanical response of materials at small length scales has gained importance due to the recent advances in micro- and nano-fabrication as well as testing systems. However, most of the ... -
Evaluation of damage in front of starting notches induced by ultra-short pulsed laser ablation for the determination of fracture toughness in zirconia
(Elsevier, 2017-12-01)
Article
Open AccessMachining a very sharp notch on the surface of ceramics for fracture toughness testing has been a critical issue during many years. In this work, we explore a novel method capable of inducing sharp features with negligible ... -
Human primary osteoblast behaviour on microrough zirconia-toughened alumina and on selectively etched microrough zirconia-toughened alumina
(Elsevier, 2018-03-01)
Article
Restricted access - publisher's policyHip arthroplasty cementless acetabular components require excellent mechanical properties, biocompatibility, low friction and good osseointegration with surrounding bone tissue. Zirconia-toughened alumina (ZTA) fulfils ... -
Effect of calcia co-doping on ceria-stabilized zirconia
(Elsevier, 2018-01-01)
Article
Open Access© 2018 Elsevier Ltd. Ceria-stabilized zirconia ceramics are characterised by excellent hydrothermal stability and high fracture toughness, but the fracture strength and hardness are lower than that of conventional 3Y-TZP, ...
