    • Grinding effects on surface integrity and mechanical strength of WC-Co cemented carbides 

      Yang, Jing; Odén, Magnus; Johansson-Jõesaar, M.P.; Llanes Pitarch, Luis Miguel (Elsevier, 2014)
      Article
      Open Access
      In this study, the correlation existing among grinding, surface integrity, and flexural strength is investigated for WC-Co cemented carbides (hardmetals). A fine-grained WC-13 wt % Co grade and three different surface ...

    • Implementation of advanced characterization techniques for assessment of grinding effects on the surface integrity of WC-Co cemented carbides 

      Yang, Jing; Roa Rovira, Joan Josep; Schwind, Martin; Odén, Magnus; Johansson-Jõesaar, M.P.; Esteve, Joan; Llanes Pitarch, Luis Miguel (2018-02-21)

      Grinding 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 ...

    • Mechanical strength of ground WC-Co cemented carbides after coating deposition 

      Yang, Jing; Odén, Magnus; Johansson-Jõesaar, M.P.; Esteve Pujol, Joan; Llanes Pitarch, Luis Miguel (2017-03-24)
      Article
      Open Access
      Manufacturing of hardmetal tools often involves surface grinding, ion etching and final coating. Each stage throughout the manufacturing chain introduces surface integrity changes which may be critical for defining the ...

    • Thermally induced surface integrity changes of ground WC-Co hardmetals 

      Yang, Jing; Roa, Joan Josep; Schwind, Martin; Odén, Magnus; Johansson-Jõesaar, M.P.; Esteve, Joan; Llanes Pitarch, Luis Miguel (Elsevier, 2016)
      Article
      Open Access
      Ground hardmetals are exposed to high temperatures during both processing (e.g. coating deposition) and use (e.g. as a cutting tool). However, studies on thermally induced changes of surface integrity are limited. Here we ...
