      Article
      Open Access
      Atom Probe Tomography (APT) was used to obtain a direct evidence of chlor segregation and cobalt diffusion at the grain boundaries (GBs) of polycrystalline coatings deposited by moderate temperature chemical vapor deposition ...
    • Contact damage investigation of CVD carbonitride hard coatings deposited on cemented carbides 

      El Azhari, Idriss; García, José; Soldera, Flavio; Suárez, Sebastian; Jiménez Piqué, Emilio; Mücklich, Frank T.; Llanes Pitarch, Luis Miguel (2020-01-01)
      Article
      Restricted access - publisher's policy
      The 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 ...
    • Contact fatigue behavior of a-Al2O3-Ti(C,N) CVD coated WC-Co under dry and wet conditions 

      Sosa, Amadeo Daniel; Collado Ciprés, Verónica; García, José; Escalada, Lisandro; Roa Rovira, Joan Josep; Soldera, Flavio; Brühl, Elisabeth; Llanes Pitarch, Luis Miguel; Simison, Sílvia Noemí (2021-02-01)
      Article
      Open Access
      The response to cycling contact fatigue load of a WC-6%Co carbide coated with a Ti(C,N)/a-Al2O3 CVD multilayer was investigated in dry and wet conditions. Imprints in dry conditions were characterized by small thin cracks ...
    • Cyclic contact fatigue of cemented carbides under dry and wet conditions: Correlation between microstructure, damage and electrochemical behavior 

      Roa Rovira, Joan Josep; Simison, Sílvia Noemí; Grasso, J.; Arcidiacono, M.; Escalada, Lisandro; Soldera, Flavio; García, José; Sosa, Amadeo Daniel (2020-11-01)
      Article
      Restricted access - publisher's policy
      The correlation between the damage induced under cyclic contact fatigue and their electrochemical behavior (anodic polarization curves) for different WC-Co-based cemented carbides grades was investigated at the macrometric ...
    • Focused ion beam tomography of zirconia degraded under hydrothermal conditions 

      Jiménez Piqué, Emilio; Ramos, A.; Muñoz Tabares, José Alejandro; Hatton, A.; Soldera, Flavio; Mucklich, F.; Anglada Gomila, Marcos Juan (Elsevier, 2012-08)
      Article
      Restricted access - publisher's policy
      Three-dimensional tomography was performed on hydrothermal degraded zirconia by sequential focussed ion beam (FIB) sectioning and field emission scanning electron microscopy (FE-SEM) observation. By means of image analysis ...
    • Investigations on micro-mechanical properties of polycrystalline Ti(C,N) and Zr(C,N) coatings

      Article
      Open Access
      Micro-mechanical properties of Ti(C,N) and Zr(C,N) coatings deposited by chemical vapor deposition on a WC-Co cemented carbide substrate were examined by micro-compression testing using a nanoindenter equipped with a flat ...
    • Micromechanical investigations of CVD coated WC-Co cemented carbide by micropillar compression 

      El Azhari, Idriss; García, José Luis; Zamanzade, Mohammad; Soldera, Flavio; Pauly, Christoph; Motz, Christian; Llanes Pitarch, Luis Miguel; Mücklich, Frank T. (Elsevier, 2020-01-15)
      Article
      Open Access
      Deformation 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 ...
    • Microstructural and metallurgical assessment of the laser-patterned cemented tungsten carbide (WC-CoNi) 

      Fang, Shiqi; Soldera, Flavio; Rosenkranz, A.; Herrmann, T.; Bähre, Dirk; Llanes Pitarch, Luis Miguel; Mücklich, Frank T. (2018)
      Conference report
      Open Access
      Cemented carbide is difficult to machine using traditional chip-removal methods due to its hardness. Electrical discharge machining (EDM) is the common method applied to shape cemented carbides because high geometric ...
    • Surface topography quantification of super hard abrasive tools by laser scanning microscopy 

      Fang, Shiqi; Llanes Pitarch, Luis Miguel; Engstler, M.; Baehre, D.; Soldera, Flavio; Muecklich, F. (2016)
      Article
