Postdoc position offer:

«Ceramic/Metal Multi-Material Assembly : Densification study by Spark Plasma Sintering»

 

Job location: CIRIMAT, Toulouse

Starting date: January 2021

Duration: 21 months

Employer: Université Toulouse 3 Paul Sabatier

Responsible: Dr Claude ESTOURNES; 0626616528; estournes@chimie.ups-tlse.fr

Please send C. ESTOURNES a CV and a cover letter before 19 November 2021

Context

SAFRAN ADDITIVE MANUFACTURING CAMPUS (SAMC) called on CIRIMAT to study the separate and combined implementation of non-conventional sintering (i.e. Spark Plasma Sintering: SPS) and Additive Manufacturing (i.e. Binder Jetting) processes on different powder materials to develop Ceramic/Metal assemblies for use in electrical applications. In particular, the influence of the material characteristics and the parameters of the two processes on their densification and the elaboration of related multi-material Ceramic/Metal assemblies will be studied. The optimizations will allow realizing coils of complex 3D shape by co-densification and meeting the electrical specifications for the intended application.

Position

  • Perform the bibliographic search on the defined project. Supply in connection with SAMC and characterize the selected materials (ceramic and metallic),
  • Define SPS densification parameters for the selected materials,
  • Define parameters for the production of green bodies by the Binder Jetting additive manufacturing technique and optimize their densification by SPS.
  • Co-densify by SPS the powder raw materials and green bodies by SPS on simple and complex geometries to obtain parts that meet the intended application.
  • Perform Physical, Chemical and mechanical characterizations of the materials and assemblies obtained.
  • Demonstrate rigor, high autonomy level, teamwork, responsiveness and adaptability.

Many characterization techniques will be used (XRD, SEM, Raman spectroscopy, electrical measurements, mechanical tests)

Position details

The candidate must hold a PhD in Materials Science. He/Her should have good knowledge’s on Spark Plasma Sintering and Additive Manufacturing processes.

Application

Please send C. ESTOURNES a CV and a cover letter before 19 November 2021
