Assessment of corrosion-induced damage in the mechanical contact response of cemented carbides at different length scales Zheng, Yafeng (Universitat Politècnica de Catalunya, 2020-12-11)
Open AccessCemented carbides, also referred to as hardmetals, are composite materials consisting of brittle refractory carbide phase (generally WC) embedded in a metallic matrix. Such microstructure leads to an outstanding combination ...

Restricted access - publisher's policyIn this study, the influence of corrosion on the mechanical response and damage induced under Hertzian indentation is assessed for three cemented carbides with metallic binders of different chemical nature. Corrosion ...
Corrosion-induced damage and residual strength of WC-Co,Ni cemented carbides: influence of microstructure and corrosion medium Zheng, Yafeng; Fargas Ribas, Gemma; Armelín Diggroc, Elaine Aparecida; Lavigne, Olivier; Llanes Pitarch, Luis Miguel (Multidisciplinary Digital Publishing Institute (MDPI), 2019-09-19)
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 ...
Indentation and scratch testing of a WC-6%wtCo cemented carbide: Corrosion effects on load-bearing capability and induced damage Zheng, Yafeng; Fargas Ribas, Gemma; Lavigne, Olivier; Llanes Pitarch, Luis Miguel (2020-04-10)
Open AccessIn this work, corrosion effects on the indentation and scratch response of a WC-6%Co hardmetal are investigated. Experimental variables include relative long corrosion times as well as indentation and scratch testing ...
Zheng, Yafeng; Fargas Ribas, Gemma; Besharatloo, Hossein; Roa Rovira, Joan Josep; Lavigne, Olivier; Llanes Pitarch, Luis Miguel (2019)
Open AccessIn this work, the effect of corrosion-induced damage on the mechanical response of hardmetals was evaluated at small-scale level by means of nanoindentation and nanoscratch. Damage was introduced in a controlled way through ...
