      Article scientifique
      Abstract : "Yttrium oxide tetragonal zirconia polycrystals (Y-TZP) is an inert bioceramic used for many bio-implantable applications that request a high accuracy which is difficult to achieve with the current technologies. Laser machining of hard ceramic is difficult because the interaction of the laser beam with the material can lead to microcracks and surface modifications of the microstructure. ...

    • Green Ceramic Machining: Determination of the Recommended Feed Rate for Y-TZP MillingPeer reviewedOpen access 

      01 septembre 2021, DEMARBAIX, Anthoninorcid-id; Mulliez, Marylou; Rivière-Lorphèvre, Edouard; Spitaels, Laurent; Duterte, Charles; Petit, Fabrice; Ducobu, François, HE Condorcet
      Article scientifique
      Abstract : "Manufacturing of advanced ceramic parts exhibiting complex geometries is laborious and expensive. Traditionally, the machining is carried out on a so-called ‘green ceramic’: a compact composed of ceramic powder held with the help of a binder. This difficulty is due not only to the composition of the material, but also to the lack of methods that determine optimal machining parameters. ...

    • Impact of Green Ceramic Hybrid Machining (GCHM) on Reliability and Repeatability of the Properties of Sintered Yttrium-Tetragonal Zirconia Polycrystal PartsPeer reviewedOpen access 

      20 juin 2023, Ducobu, François; DEMARBAIX, Anthoninorcid-id; Rivière-Lorphèvre, Edouard; Spitaels, Laurent; Petit, Fabrice; Preux, Nicolas; Duterte, Charles; Mulliez, Marylou; Lauwers, Bert, HE Condorcet
      Article scientifique
      Abstract : "The innovative Green Ceramic Hybrid Machining (GCHM) process sequentially combines milling with a cutting tool (GCM, Green Ceramic Machining) and laser beam machining (GCLBM) of a ceramic material (black Y-TZP in this study) at the green stage mainly to increase productivity, avoid taper angle limitations of laser beam machining, and obtain micro-features. The study focuses on ...
