The project “Laser Implantation Surface Texturing (LITex)— Fundamentals and Applications” aims towards a breakthrough manufacturing system for the fabrication of functional surfaces. The two main research activities underpinning the system surround the prediction (and opitimization) of the added volume, microstructure and stresses in the laser-based AM for the development of tailored surface properties of metallic components and secondly, the development of a pulsed powder delivery system.
To predict the relationship between processing conditions (laser parameters and material parameters) and resulting added material you will:

  • develop numerical models of Laser-Material Interaction and Micro Melt Pool dynamics:
    • numerical simulation of rapid pool forming
    • micro-stresses and strains
    • choose appropriate advanced numerical techniques and optimize them for simulation of micro-scale manufacturing;
    • validate your simulation models by measurements on actually produced samples;

Utilising the results above, a pulsed powder delivery system will be realised based on:

  • Definition of process requirements and limitations
  • Design and build of application system
  • Testing of pulsed powder deposition technology

In addition you will take initiative and responsibility in that:

  • You will closely collaborate with your research-team colleagues at University of Twente, as well as with the industrial partner;
  • You will mentor BSc and MSc students, who do graduation projects in support of your research;
  • You will aim at finishing your research with a PhD thesis.

Benefits

The university offers a dynamic, international workplace with enthusiastic colleagues in a stimulating scientific environment. The PhD salary is € 2.325 in the first year and increases to € 2.972 in the fourth year. Additional benefits are:

  • A holiday allowance of 8% of the gross annual salary and a year-end bonus of 8.3%;
  • A solid pension scheme;
  • Minimum of 29 holidays in case of full-time employment;
  • Professional and personal development programs.

  • You are willing and able to collaborate closely with other researchers and the Industrial partner;
  • You are aware of:
    • fundamental aspects of high power laser-material processing, such as laser cladding,
    • analysis technologies/techniques such as SEM, EDX, AFM, confocal microscopy, etc;
  • You like to present your results to colleagues, industrial partners and at international conferences;
  • You are fluent in English and express yourself easily both in speech and in writing. We require a TOEFL > 90 or IELTS > 6.5 score.
