Tribological performance of AlCrN and TiAlN coatings in aluminum forming process at high temperature

Panuwat Soranansri, André Dubois, Philippe Moreau, Tatsuya Funazuka, Kuniaki Dohda, Laurent Dubar

Material transfer is a critical tribological issue in aluminum forming processes, particularly at high temperatures. Although applying PVD or CVD coatings on the forming tool surface could be a solution to alleviate the material transfer issue, selecting an appropriate coating with sufficient...

POSTER

Surface Topography: An indicator for the Authentication of Painters’ artworks

François Berkmans, Ludovic Nys, Michal Wieczorowski, Maxence Bigerelle

The aim of the analysis is to examine Van Gogh's paintings using fractal measurements, showing that authentic works exhibit a high fractal dimension (between 2.7 and 2.8). Specific cases, such as Sunset at Montmajour and The Ploughmen, are discussed to either confirm or reject their...

A Process-Centered Approach of lubrication and wear in cold and hot metal forming

Laurent Dubar, Mirentxu Dubar, Philippe Moreau, André Dubois

Cold and hot metal forming processes are families of manufacturing processes where tools apply compressive forces to shape a workpiece to a given geometry. These compressive forces generate high contact pressures and high plastic strains near the workpiece surface. They lead to shear stresses due...

REPORT

Management des risques éthiques au travail : Études de cas

Hiba Belgziz, Lucas Dancoisne, Romane Paquez, Soulayma Sabri, Damien Trentesaux

Ce rapport présente différentes études qui ont été menées sur des cas de conflits éthiques en entreprise. L’étude démontre quels sont les facteurs qui participent à l’émergence de ces conflits, comment ils ont été gérés en interne et la méthode qui aurait pu être appliquée. Différentes catégories...

Materials-Processes connections under extreme dynamic conditions, Couplages Matériaux-Procédés en conditions dynamiques extrêmes

Benjamin Zielinski

The objective of this thesis was to investigate the influence of the Magnetic Pulse Welding (MPW) process on the materials properties, and characteristics of the obtained joint. Several material couples were examined, with a specific focus on the Copper/Copper (Cu/Cu), and Aluminum/Copper (Al/Cu)..., L'objectif de ce travail de thèse était d'étudier l'impact du procédé du magnéto-soudage sur les propriétés des matériaux, ainsi que des caractéristiques du joint obtenu. Différents couples de matériaux ont été étudiés, une attention particulière a été portée sur le couple Cuivre/...
